Ives 5BB1 4.5x4.5 652 – Frequently Asked Questions

1) Will an Ives 5BB1 hinge hold a heavy commercial door, or do I need a heavy weight hinge?
150 lbs is the ceiling on the 5BB1, at up to 400 cycles per day. That is medium duty: hollow metal and wood doors in offices, classrooms, corridors, and unit entries. Over that weight, or on an entrance that gets hammered all day, step up to a heavy weight hinge. Don-Jo's HWBB74545 (4-1/2 x 4-1/2) and HWBB75045 (5 x 4-1/2) are heavy weight full mortise ball bearing hinges, and Hager's BB1168 is a heavy duty full mortise ball bearing hinge with a non-removable pin. Weigh or estimate the leaf before you commit, because an overloaded hinge sags the door and the closer never adjusts right afterward.
2) What size Ives 5BB1 hinge do I order for a 1-3/4 inch commercial door?
Six sizes are made: 3.5 x 3.5, 4 x 4, 4.5 x 4, 4.5 x 4.5, 5 x 4.5, and 5 x 5. Hinge sizes read height first, then the open leaf width, and leaf width is what has to cover the door thickness plus enough clearance for the door to swing past the trim. On a standard 1-3/4 inch commercial door up to roughly 36 inches wide, 4.5 x 4.5 is the usual call; wider doors go to 5 x 4.5 or 5 x 5. The 3.5 and 4 inch sizes belong on 1-3/8 inch interior doors. If you are replacing, pull one hinge and measure it rather than guessing from the door.
3) Will the Ives 5BB1 fit the hinge prep already cut in my frame and door?
Built to ANSI/BHMA A156.7 template hinge dimensions, so the leaf geometry and screw hole pattern match standard commercial prep for the same size. Corners are square, which is the prep on most hollow metal frames and factory-prepped hollow metal doors. Where it will not go is a radius corner pocket: if the hinge coming out has rounded corners, a square leaf will not seat, and you want a radius corner hinge instead. Orca's 3.5 x 3.5 and 4 x 4 commercial hinges are cut with a 1/4 inch radius corner for exactly that pocket. Take one existing hinge off and match size, corner, and finish code from it.
4) Do I need ball bearing hinges on a door with a closer, or will plain bearing hinges do the job?
Put ball bearings on anything with a closer. The 5BB1 carries two ball bearing assemblies between its five knuckles, and Ives recommends it on closer-equipped openings, because a closer loads the hinge on every single cycle and a plain bearing wears flat under that. Grade 2 at 1,500,000 cycles is the durability behind that recommendation. Plain bearing is the cheaper right answer only on light interior doors with no closer and low traffic: Orca's 4 x 4 square corner plain bearing commercial hinge or Hager's 920 two knuckle concealed plain bearing hinge cover that case.
5) What hinge carries power to an electric lock in place of the Ives 5BB1?
The Ives 5BB1 is a mechanical ball bearing full mortise hinge. When the opening needs power run through the hinge to an electric lock or exit device, the energy transfer builds are the Command Access ETH-BB68, a 5 knuckle energy transfer hinge on a heavy duty steel base, and the Command Access ETH-CB70, a 3 knuckle standard weight steel base version rated medium duty. The BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect, medium duty, and the Stanley CECB1900R54L is a three knuckle concealed bearing concealed conductor hinge, steel full mortise, standard weight, 4-1/2 by 4-1/2 square corner, left-handed, with 4 wires. Two things drive the pick: wire count, which has to cover the device you are feeding, and handing, since the Stanley is supplied left-handed.
6) What is the closest cross-brand equivalent to the Ives 5BB1 ball bearing hinge for a standard commercial opening?
The Ives 5BB1 is a 5-knuckle ball bearing full mortise hinge with square corners on a steel substrate, designated medium duty. The nearest builds from other makers are the Orca Hardware 3535, a 4-1/2 by 4-1/2 square corner ball bearing commercial hinge also rated medium duty, and the Delaney CH401X, a 4 by 4 commercial ball bearing hinge with square corners. Both match the 5BB1 on bearing type and corner style at those sizes, so square corner pockets already routed in the door and frame carry over without re-prep. The 5BB1 runs a broader size range, from 3-1/2 by 3-1/2 through 5 by 5, so a building standardized on 5 by 4-1/2 or 5 by 5 stays inside one model.
7) The door is heavier than 150 lbs. What ball bearing hinge should I use instead of the Ives 5BB1?
The Ives 5BB1 is built for commercial doors up to 150 lbs at medium-frequency use up to 400 cycles per day. Above that weight, the heavy duty full mortise ball bearing options are the Don-Jo HWBB74545 and HWBB84545 heavy weight hinges in 4-1/2 by 4-1/2, the Don-Jo HWBB75045 heavy weight hinge in 5 by 4-1/2 steel, and the Hager BB1168 full mortise ball bearing hinge, all four rated heavy duty. Each is a full mortise ball bearing hinge like the 5BB1, so the frame preparation type is unchanged; what changes is the heavy weight leaf and the duty rating. Confirm the leaf size you need matches, since the Don-Jo heavy weight offerings above are 4-1/2 by 4-1/2 and 5 by 4-1/2.
8) The existing hinge pockets have rounded corners. What takes the place of the Ives 5BB1 there?
The Ives 5BB1 is a square corner hinge, so it wants a square routed pocket. Where the door and frame are already cut with radius corners, the matching builds are the Orca Hardware 4014, a 4 by 4 hinge with 1/4 inch radius corners and plain bearing function, and the Orca Hardware 3514 at 3-1/2 by 3-1/2 with the same 1/4 inch radius, both medium duty. Delaney supplies 5/8 inch radius sets in 3-1/2 by 3-1/2 interior and 4 by 4 exterior, and the Deltana DE44R5TA is a 4 by 4 steel hinge with 5/8 inch radius corners. Radius is not one dimension: check whether the existing pocket is cut at 1/4 inch or 5/8 inch before ordering, because the two do not interchange.
9) For an out-swinging exterior door where the pin must not be pullable, what is the alternative to the Ives 5BB1?
The Ives 5BB1 is a ball bearing full mortise steel hinge with square corners. For an out-swing where the hinge barrel is on the exterior and the pin has to stay put, the Hager BB1168 is a non-removable pin full mortise ball bearing hinge rated heavy duty, which keeps the same full mortise ball bearing construction as the 5BB1. The Deltana CSB45N is a 4-1/2 by 4-1/2 square corner hinge supplied in pairs with a non-removable pin, and the Deltana DE44R5TA is a 4 by 4 security hinge in steel, supplied in pairs, with 5/8 inch radius corners. Corner prep is the deciding detail between them: the Hager and the Deltana CSB45N sit in square pockets like the 5BB1, while the DE44R5TA needs a 5/8 inch radius cut.
10) Do Ives 5BB1 hinges come with screws, or do I have to order fasteners separately?
Screws are in the box, and both kinds are there. Each 5BB1 ships with machine screws for tapped hollow metal (12-24 x 1/2 inch and 10-24 x 1/2 inch) and wood screws for wood doors and wood frames (12 x 1-1/4 inch and 10 x 1 inch). That covers the common commercial case of a hollow metal frame with a wood door without sending anyone back to the truck for a second box of fasteners.
11) Is there a non-removable pin option on the Ives 5BB1 for an out-swinging exterior door?
Not an option you can specify. The 5BB1 is ordered on size and finish, and a non-removable pin is not one of those choices. On an out-swinging exterior door, or a secured room where the barrel ends up on the unsecured side, that matters, because a removable pin is a way past the lock. Hager's BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge, and Deltana's CSB45N is a 4-1/2 x 4-1/2 square hinge sold in pairs with a non-removable pin. On an in-swinging door the barrel sits on the secure side and the 5BB1 is fine as is.
12) What finishes does the Ives 5BB1 hinge come in? I need to match hinges already hung on other doors.
Twelve finishes: 600 primed for painting, 631 matte black, 632 bright brass, 633 satin brass, 639 satin bronze, 640 satin bronze dark, 641 oxidized bronze, 643E aged bronze, 646 satin nickel, 651 bright chrome, 652 satin chrome, and 695 dark bronze. Match by the number stamped on an existing hinge, not by eye. 652 satin chrome and 646 satin nickel read almost the same on a hung door and look wrong the moment they are side by side in a corridor. Order 600 primed when the hinges get painted along with the frame.
13) What is the closest equivalent to the Ives 5BB1 from another brand?
On configuration, McKinney's MP79 and MPB79 MacPro hinges are the nearest match: five knuckle, full mortise, standard weight. If you are matching on size and corner instead, Orca's 4-1/2 x 4-1/2 square corner ball bearing commercial hinge is medium duty like the 5BB1, and Delaney's CH401X is a 4 x 4 commercial ball bearing hinge with square corners. Where the 5BB1 separates itself is on a spec-driven job: ANSI/BHMA A156.1 certified, Grade 2 at 1,500,000 cycles, and UL Classified for windstorm rated assemblies are what an architect writes into a hardware schedule.
14) Can I standardize on one Ives 5BB1 hinge across a whole building?
Mostly, and that is the point of it. One model covers six sizes from 3.5 x 3.5 up to 5 x 5 in twelve finishes, and A156.7 template dimensions keep the prep consistent from opening to opening, so a maintenance stock of two sizes in one finish services most of a building. Where it stops is the 150 lb and 400 cycles per day ceiling. Main entrances, high traffic stairwells, and oversized doors want a heavy weight hinge, and any opening with an electric lock needs a transfer hinge in one position. Offices, classrooms, unit entries, and corridor doors all take the same 5BB1.
15) Is a plain bearing commercial hinge the same thing as the Ives 5BB1?
They are different bearing arrangements. The Ives 5BB1 is a ball bearing hinge with two ball bearing assemblies and 5 knuckles, and it is recommended for use with door closers. The plain bearing commercial hinges alongside it are the Orca Hardware 4040, a 4 by 4 square corner plain bearing commercial hinge rated medium duty, the Orca Hardware 4014 in the same size with 1/4 inch radius corners, the Emtek 92013 plain bearing pair at 3-1/2 by 3-1/2 with square corners in plated steel, and the Schlage Residential S3P1010, a 3-1/2 by 3-1/2 square corner plain bearing mortise hinge supplied three to a pack. Leaf size and corner style can match exactly while the bearing type does not, so specify the bearing arrangement, not just the size, when you order against a 5BB1 opening.
16) I need door position monitoring at the hinge. What are the options next to the Ives 5BB1?
The Ives 5BB1 is a ball bearing full mortise hinge with 5 knuckles and no monitoring function built into it. Where the access control system needs to know the door is closed, the Command Access ETM-BB68 is an energy transfer monitor hinge with an integrated door position switch on a heavy duty base, and the Command Access ETM-CB70 is a 3 knuckle steel base energy transfer monitor hinge with door position sensing, rated medium duty. Both combine the power transfer path and the position signal in a single hinge, which is a different scope of work from hanging the door on a 5BB1 and running a separate door contact.
17) What replaces the Ives 5BB1 on a detention or correctional opening?
The Ives 5BB1 is a Grade 2 commercial hinge rated medium duty for doors up to 150 lbs. Detention openings are hung on a different class of hinge entirely: the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge in the detention hardware series, the Stanley BB855 is a double weight prison hinge at 5 by 6, furnished with no holes and not swaged, and the Hager 990 STEEL is a full surface prison hinge at 3 by 4 with a welded tip, rated heavy duty. Two of those change the install as well as the hinge: the Stanley arrives undrilled and unswaged so it is prepped to the opening, and the Hager 990 applies to the face of the door and frame rather than into a mortise pocket.
18) Can a spring hinge do the job of the Ives 5BB1 on a self-closing door?
They close the door by different means. The Ives 5BB1 is a ball bearing full mortise hinge recommended for use with a door closer, so the closing force comes from a separate device mounted to the door or frame. The Stanley 2060R is a full mortise spring hinge with square corners at 4-1/2 by 4-1/2 on a ferrous steel base, rated heavy duty, and it carries the closing spring inside the hinge itself. At 4-1/2 by 4-1/2 with square corners it shares the prep the 5BB1 uses at that size, so the pocket does not change; what changes is whether the opening also gets a closer and how the closing force is adjusted.
19) Which other 5-knuckle full mortise hinges are built the way the Ives 5BB1 is?
The Ives 5BB1 is a 5-knuckle full mortise hinge on a steel substrate, medium duty, ANSI/BHMA A156.1 and Grade 2. Peers with the same knuckle count and mounting type include the McKinney MP79 MacPro full mortise hinge, 5-knuckle standard weight, the McKinney MPB79 MacPro 5-knuckle standard weight hinge, and the Stanley FBB191, a 5-knuckle full mortise standard weight hinge at 4-1/2 by 4-1/2. The McKinney T2314 is also a 5 knuckle standard weight hinge, rated medium duty, but on a non ferrous base rather than steel. Knuckle count matters here beyond appearance: a five knuckle barrel lines up with an existing 5BB1 barrel in a fleet of openings where a two or three knuckle hinge will not.
20) The Ives 5BB1 is a steel hinge. Which comparable hinge uses a non-ferrous base?
The Ives 5BB1 is built on a steel substrate and is offered in twelve finishes, including 600 primed for painting, 630 and 652 satin chrome variants, 646 satin nickel and 695 dark bronze. Where the specification calls for a non-ferrous base material instead of steel, the McKinney T2314 is a non ferrous hinge, standard weight, 5 knuckle, rated medium duty, which matches the 5BB1 on knuckle count and duty level while changing the base metal. Base material and finish are separate decisions: a finish applied over steel is not the same specification as a non-ferrous hinge, so read the drawing carefully before substituting one for the other.
21) The frame will not take a full mortise pocket. What hinge works there in place of the Ives 5BB1?
The Ives 5BB1 is a full mortise hinge, which means both leaves sit in routed pockets, one in the door edge and one in the frame rabbet. Where the frame cannot be mortised, the Hager 1129 is a half mortise plain bearing commercial hinge at 4-1/2 in standard weight steel, mortised into the door and applied to the face of the frame, and the Hager 990 STEEL is a full surface prison hinge at 3 by 4 with a welded tip, rated heavy duty, which applies to the faces of both door and frame with no routing at all. Mounting type is the first thing to settle on a retrofit, because a full mortise hinge and a half mortise hinge of the same leaf size are not interchangeable in the same opening.
22) For a door that has to swing both directions, what takes the place of the Ives 5BB1?
The Ives 5BB1 is a full mortise butt hinge, which hangs a door swinging one way off pockets cut in the door edge and frame rabbet. A door that needs to push open in both directions runs on a pivot instead: the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors, in the emergency rescue hardware series. That is a different install rather than a different hinge, since the pivot carries the door at top and bottom rather than along the hinge edge, and the frame and floor preparation follow the pivot rather than the hinge template.
23) What is a lighter alternative to the Ives 5BB1 for interior residential doors?
The Ives 5BB1 is designated a commercial hinge, ANSI/BHMA A156.1 Grade 2, with a ball bearing barrel sized for openings running up to 400 cycles a day. On apartment interior doors that do not see that traffic, the residential-duty options are the Deltana DSB35, a 3-1/2 by 3-1/2 square corner residential hinge supplied in pairs, the Emtek 91013 residential plain bearing pair at 3-1/2 by 3-1/2 with square corners in plated steel, the Deltana DSB3 at 3 by 3 in pairs, and the Delaney bulk residential sets in 3-1/2 by 3-1/2 interior and 4 by 4 exterior with 5/8 inch radius corners. Match the corner style to the door: the Deltana and Emtek options above are square corner like the 5BB1, while the Delaney sets are cut for a 5/8 inch radius.
24) Can I use residential hinges on apartment corridor and unit entry doors instead of a commercial hinge?
Those are commercial openings, and the 5BB1 is what belongs on them: steel, five knuckles, two ball bearing assemblies, ANSI/BHMA A156.1 certified at Grade 2 for 1,500,000 cycles. Residential hinges are a different product. Emtek's 91013 and Schlage's S3P1010 are plain bearing residential hinges in 3-1/2 x 3-1/2, which are right for closet and bedroom doors inside a unit, and wrong under a corridor door on a closer that swings a few hundred times a day. Multi-family owners who mix the two end up replacing the residential ones twice.
25) Which hinge do I use if I need door position monitoring on a commercial opening?
Not the 5BB1, which is a mechanical hinge with no switch in it. Command Access ETM-BB68 is an energy transfer monitor hinge with an integrated door position switch, and ETM-CB70 is the 3 knuckle version with door position sensing. Both put the contact inside the hinge instead of surface mounting a magnetic contact at the head, which keeps it out of reach and out of sight. One monitor hinge goes in a single position and the remaining hinge positions on that door take standard 5BB1s in the matching size and finish.
26) What is the difference between the Ives 5BB1 and a concealed bearing hinge?
The Ives 5BB1 carries its bearings in a visible 5-knuckle barrel: two ball bearing assemblies, square corners, steel substrate, medium duty. A concealed bearing hinge hides the bearing inside the barrel and often changes the knuckle count with it. The Hager 920 is a full mortise concealed plain bearing hinge with 2 knuckle steel construction, rated medium duty, the BEST CB1969R is a concealed bearing heavy weight pivot-reinforced hinge rated heavy duty, and the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge, medium duty. Where a run of openings is already hung on 5BB1 hinges, the visible barrel of a 2 or 3 knuckle concealed bearing hinge will read differently in the same corridor even at the same leaf size.
27) At 3-1/2 by 3-1/2 with square corners, which ball bearing hinges compare to the Ives 5BB1?
The Ives 5BB1 is offered at 3-1/2 by 3-1/2 with square corners, ball bearing, on a steel substrate, and is designated commercial. At that same leaf size and corner style, the Emtek 94013 is a heavy duty ball bearing pair in plated steel with square corners, and the Emtek 96213 is a heavy duty pair, also 3-1/2 by 3-1/2 square corner. The Emtek pairs share the pocket dimensions and the bearing type, so they drop into a 3-1/2 square pocket the same way; the difference to check is packaging, since those are supplied as pairs, and whether the opening is specified as a commercial application.
28) Is the McKinney SQ3331 square barrel hinge a substitute for the Ives 5BB1?
They are built differently despite both being offered at 4-1/2 by 4-1/2. The McKinney SQ3331 is a square barrel 2-knuckle decorative hinge at 4-1/2 by 4-1/2, rated standard duty. The Ives 5BB1 at that leaf size is a 5-knuckle ball bearing hinge with square corners, medium duty, ANSI/BHMA A156.1 Grade 2 at 1,500,000 cycles. The knuckle count and the bearing arrangement are the substance of the difference: a two knuckle decorative barrel and a five knuckle ball bearing barrel will not read alike in a run of openings, and the duty designations are not the same.
