Ives 5BB1 NRP 5-Knuckle Ball Bearing Hinge, Standard Weight, 4-1/2" x 4-1/2", Non-Removable Pin

The Ives 5BB1 4.5" x 4.5" is an industry-standard, commercial-grade ball bearing hinge designed for medium-weight doors or doors requiring low-frequency service. When specified with Electrification Options, it becomes a critical component of an access control system, allowing power to be transferred from the frame to the door for hardware like electric strikes, exit devices, or electrified locks.

 

Product Specifications

  • Model: 5BB1 (5-Knuckle, Ball Bearing)

     

  • Size: 4.5" x 4.5" (The standard size for 1-3/4" thick commercial doors)

  • Weight: Standard Weight (designed for typical commercial foot traffic)

  • Base Material: Available in Steel (5BB1), Stainless Steel (5BB1SS), or Brass (5BB1BS)

     

  • Bearings: Two ball bearing races to reduce friction and prevent sagging

     

Electrification Options

When used in security applications, the 5BB1 can be modified with several power-transfer technologies:

  1. EPT (Electric Power Transfer) Prep: The hinge is prepared to work in conjunction with a separate power transfer unit.

  2. TWP (Through-Wire): The hinge barrel is modified to allow low-voltage wires to pass through.

    • TW4: 4-wire configuration.

    • TW8: 8-wire configuration.

    • TW12: 12-wire configuration.

  3. CON (Allegion Connect): Features a "plug-and-play" Molex-style connector. This eliminates the need for wire nutting and reduces installation time and errors when connecting to other Allegion electrified hardware (like Von Duprin exit devices or Schlage locks).

  4. MON (Monitor Switch): Includes an internal switch that signals whether the door is open or closed to a security console.

Ives 5BB1 4.5X4.5 626 NRP – Frequently Asked Questions

1) Will an Ives 5BB1 4-1/2 x 4-1/2 hinge work on a standard 1-3/4 inch commercial door?
Yes. The 5BB1 at 4-1/2 x 4-1/2 inches is the standard full mortise size for 1-3/4 inch thick commercial doors, and it's built for commercial use rather than residential. It's a five knuckle, ball bearing, square corner hinge, so the door leaf and frame prep both need square corner mortises, not radius corner. If your existing hinges have rounded corners you'll be filling and re-routing the mortise or using a corner shim.
2) What does NRP mean on a hinge and do I need it on an out-swinging exterior door?
NRP is a non-removable pin. A set screw in the barrel seats against the pin so it can't be driven out with the door closed. It matters on any out-swing door where the hinge barrel is on the outside of the opening, exterior entries, stair and tenant doors, unit entries in multi-family. Without it, someone knocks the pins out and lifts the door off regardless of what lock you have. On an in-swing door with the barrel on the secure side, NRP is optional.
3) Is a standard weight ball bearing hinge enough for my door, or do I need heavy weight?
The 5BB1 is standard duty, sized for medium weight doors or openings with lower traffic frequency. Two ball bearing races carry the load and keep the door from sagging. If you're hanging a heavy solid core or metal-clad door, or an opening that cycles constantly like a main entry or a corridor cross door, step up to a heavy weight hinge. The Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge in the same 4-1/2 x 4-1/2 size, and the Hager BB1168 NRP is a heavy duty full mortise ball bearing hinge that also carries the non-removable pin.
4) Which electrified option do I order to run power through the hinge for an electric lock or exit device?
Four routes on the 5BB1. TWP through-wire modifies the barrel to pass low voltage wire, ordered as TW4, TW8 or TW12 depending on how many conductors your hardware needs, four for a simple electric strike or latch retraction, eight or twelve when you're carrying request-to-exit, latch monitoring and door position back too. EPT prep means the hinge works alongside a separate power transfer unit rather than carrying the wire itself. CON is Allegion Connect, a Molex style plug-and-play connector that drops the wire nutting when you're landing on other Allegion hardware like Von Duprin exit devices or Schlage locks. MON adds an internal switch that reports door open or closed to the security console. Count your conductors before you specify, going back to change a hinge means pulling the door.
5) Can I swap an Ives 5BB1 straight into an existing 4-1/2 inch hinge mortise?
If what's in the door now is a 4-1/2 x 4-1/2 square corner full mortise hinge, the 5BB1 drops into the same prep. Two things to check first: corner style, since the 5BB1 is square corner and won't sit right in a radius corner mortise, and whether the existing hinge is standard or heavy weight, because heavy weight leaves are thicker and a standard weight hinge in that mortise will sit proud or shallow. In the same 4-1/2 x 4-1/2 square corner size, the Orca 3535 Series ball bearing commercial hinge and the Deltana CSB45N square hinge with non-removable pin are alternatives that share the footprint.
6) Can I use the Ives 5BB1 on residential 3-1/2 inch hinge cutouts?
No. At 4-1/2 x 4-1/2 the 5BB1 is a full inch taller and wider than a 3-1/2 inch residential hinge, so it won't drop into that mortise without recutting both the door and the jamb. For 3-1/2 inch residential and light interior prep, look at the Emtek 91013 residential plain bearing hinges, the Emtek 94013 heavy duty ball bearing version, the Deltana DSB35 square hinge, or the Schlage Residential S3P1010 3.5 inch square corner mortise hinges in a pack of three, which suits a whole door in one buy.
7) What is the alternative to a 5BB1 with a monitor switch if door position signaling is required?
Command Access builds door position sensing into the hinge itself. The ETM-BB68 is an energy transfer monitor hinge with an integrated door position switch on a heavy duty base, and the ETM-CB70 is an energy transfer monitor hinge with door position sensing on a three knuckle steel base at medium duty. Both combine the power transfer and the monitoring function in one hinge, so the door does not need a separate position switch in the frame. The Ives 5BB1 is a five knuckle ball bearing hinge with square corners; the Command Access ETM-BB68 is heavy duty where the ETM-CB70 is medium duty, so match the choice to the door weight.
8) What is the closest equivalent to an Ives 5BB1 4-1/2 x 4-1/2 five-knuckle ball bearing hinge from another manufacturer?
The McKinney MP79 MacPro full mortise hinge is the closest match in construction: it is a five-knuckle, standard weight full mortise hinge at the same standard duty level as the Ives 5BB1. The McKinney MPB79 MacPro is also a five-knuckle standard weight hinge. If you want to stay at 4-1/2 x 4-1/2 with square corners, the Orca Hardware 3535 Series is a 4-1/2 x 4-1/2 square corner ball bearing commercial hinge, and the Stanley Security FBB191 is a five-knuckle full mortise standard weight hinge in 4-1/2 x 4-1/2. All four are full mortise hinges that go into the same frame and door prep as the 5BB1.
9) The door is heavier than standard weight - what ball bearing hinge should be used instead of a standard weight 5BB1?
Step up to a heavy weight ball bearing hinge in the same 4-1/2 x 4-1/2 full mortise footprint. The Don-Jo HWBB74545 and HWBB84545 are heavy weight full mortise ball bearing hinges at 4-1/2 x 4-1/2. Where the door is wide as well as heavy, the Don-Jo HWBB75045 and HWBB85045 are heavy weight full mortise ball bearing hinges in 5" x 4-1/2", which gives more leaf on the door face. If the opening needs a non-removable pin for an outswing door, the Hager BB1168 NRP is a heavy duty full mortise ball bearing hinge with a non-removable pin.
10) What hinge should be used instead of an electrified 5BB1 when the power transfer needs to be concealed in the barrel?
For concealed conductor construction, the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect, and the Stanley Security CECB1900R54L is a three knuckle concealed bearing, concealed conductor architectural hinge, steel full mortise, standard weight, 4-1/2 x 4-1/2, square corner, left-handed, 4-wire. Command Access offers the ETH-BB68, a five knuckle heavy duty steel base energy transfer hinge, and the ETH-CB70, a three knuckle standard weight steel base energy transfer hinge. Note the Stanley CECB1900R54L is handed left, so confirm the swing before ordering; the Ives 5BB1 in its standard form is a five knuckle ball bearing hinge with square corners.
11) Which 4-1/2 x 4-1/2 hinge has a non-removable pin like the 5BB1 NRP?
The Deltana CSB45N is a 4-1/2" x 4-1/2" square hinge with a non-removable pin, sold as a pair, which matches the leaf size, the square corner and the NRP feature of the Ives 5BB1 NRP. For a heavier door, the Hager BB1168 NRP is a full mortise ball bearing heavy duty hinge with a non-removable pin. The Deltana DE44R5TA is also a security hinge but it is 4" x 4" with a 5/8" radius and uses tamper-resistant screws rather than a non-removable pin, so it is a different security approach on a different prep.
12) The door needs to self-close or swing both ways - is there an alternative to the 5BB1?
Those are different hinge types, not finishes of the same one. For self-closing, the Stanley Security 2060R is a spring hinge, full mortise, square corner, 4.5" x 4.5", ferrous steel base, heavy duty - it matches the 4-1/2 x 4-1/2 square corner full mortise prep of the Ives 5BB1 but adds the closing spring. For a door that swings both directions, the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors, which is a pivot set and needs pivot prep at the top and bottom of the door rather than hinge mortises in the edge.
13) What's the difference between a ball bearing hinge and a plain bearing hinge?
Ball bearing hinges put bearing races between the knuckles so the leaves ride on bearings instead of steel on steel. That's what keeps a heavier door swinging freely and stops it sagging over years of cycles. Plain bearing hinges have no races and are the cheaper choice for light interior doors that don't get much traffic. The 5BB1 is a ball bearing hinge. If you're doing light interior openings and don't need bearings, the Orca Hardware 4040 Series 4 x 4 square corner plain bearing commercial hinge or the Hager 1129 half mortise plain bearing hinge cover that end.
14) Do Ives 5BB1 hinges come with screws for both wood and hollow metal frames?
Both. The 5BB1 ships with wood screws and machine screws, so the same hinge covers a wood door into a wood jamb and a door into a tapped hollow metal frame. On hollow metal you use the machine screws into the frame's tapped holes; on wood you use the wood screws. Worth pulling one long screw per hinge into the stud behind a wood jamb on heavier doors.
15) What standard does the Ives 5BB1 hinge meet for a spec job?
ANSI/BHMA A156.1, the hinge standard. That's the line to put on the submittal for an institutional or government opening where the spec calls out a butt hinge standard. It's a commercial-rated hinge, not a residential one, and the model designation to write on the schedule is 5BB1 with NRP for the non-removable pin.
16) What finishes does the Ives 5BB1 hinge come in so I can match the rest of my door hardware?
Ten finishes: 606 satin brass, 633 satin brass, 613 oil rubbed bronze, 640 oil rubbed bronze, 619 satin nickel, 626 satin chrome, 652 satin chrome, 630 satin stainless, 695 dark bronze and 631 matte black. Order by the BHMA number, not the plain name, because the pairs differ in base material and plating even where the description reads the same. 626 and 652 are the usual matches for satin chrome lever and closer hardware, and 630 is the one to specify with stainless trim on exterior openings.
17) Is the Ives 5BB1 available in stainless steel or brass for a coastal or exterior opening?
Yes. The 5BB1 base material comes in steel, stainless steel as the 5BB1SS, and brass as the 5BB1BS. On coastal, pool room, or wash-down openings the stainless base is the one to specify, the plating on a steel hinge is what fails first in that environment. Note that finish and base material are separate decisions, so name both when you order.
18) Do I need to order a left hand or right hand Ives 5BB1 hinge?
No handing to specify. The 5BB1 is a full mortise butt hinge with a symmetrical five knuckle barrel, so the same part hangs a left hand or right hand door, you just flip it. Handing only enters the picture on the electrified versions where a concealed conductor exits one specific side, which is why a hinge like the Stanley CECB1900R54L is called out as left-handed. For the plain 5BB1 NRP, order quantity and finish and you're done.
19) I want the door to close by itself without a closer, will the 5BB1 do that?
No. The 5BB1 is a plain butt hinge on ball bearings, it swings freely and stays where you leave it. For self-closing without a surface closer you want a spring hinge, and the Stanley Security full mortise spring hinge comes in the same 4-1/2 x 4-1/2 square corner size so it drops into the same prep. Be aware that on a fire or life-safety opening a spring hinge is not automatically an acceptable self-closing device, so check what your local authority accepts before you substitute one for a closer.
20) What should I use instead of a five knuckle butt hinge on a detention or high-abuse door?
A standard duty five knuckle butt hinge like the 5BB1 is the wrong part for a detention or heavy-abuse opening. For those, the BEST BB855 is a heavy duty steel double weight concealed ball bearing prison hinge, the Stanley double weight prison hinge comes 5 by 6 inches furnished with no holes and not swaged so it can be welded and drilled to suit, and the Hager 990 STEEL is a full surface prison hinge 3 x 4 inches with a welded tip. Where a door needs to swing both directions, the BEST DAP-3 double acting pivot handles that instead of butt hinges entirely.
21) Is there a five knuckle standard weight full mortise hinge from another brand if I'm standardizing a building?
McKinney's MacPro line is the closest match on paper: the MP79 is a five knuckle standard weight full mortise hinge and the MPB79 is the five knuckle standard weight MacPro hinge, both standard duty like the 5BB1. Stanley's FBB191 is a five knuckle full mortise standard weight hinge in 4.5 x 4.5. If your building already runs Allegion hardware, Von Duprin devices or Schlage locks, staying on Ives keeps the CON plug-and-play connector option open on the electrified openings, which is the real argument for standardizing on one brand.
22) Can a plain bearing commercial hinge be used in place of a 5BB1 ball bearing hinge?
They are not the same thing. The Ives 5BB1 is a ball bearing hinge with two ball bearing races that reduce friction and prevent sagging. Plain bearing peers such as the Orca Hardware 4040 Series 4" x 4" square corner plain bearing commercial hinge, the Orca 4014 Series 4" x 4" x 1/4" radius corner plain bearing hinge, and the Hager 1129 half mortise plain bearing hinge use no bearing races. Plain bearing is generally specified for lower traffic or lighter doors. Also note the Orca 4040 and 4014 are 4" x 4" and the Hager 1129 is a half mortise, not a full mortise, so neither drops into a 4-1/2 x 4-1/2 full mortise prep without changing the door and frame.
23) Is a residential 3-1/2 inch ball bearing hinge an acceptable substitute for a 5BB1 on a commercial opening?
No. The Ives 5BB1 is a commercial hinge certified to ANSI/BHMA A156.1 at 4-1/2 x 4-1/2. Peers such as the Emtek 94013 heavy duty ball bearing hinges and the Emtek 91013 residential plain bearing hinges are 3-1/2 x 3-1/2 with square corners in plated steel and ship as a pair, and the Schlage Residential S3P1010 is a 3.5" x 3.5" square corner plain bearing mortise hinge sold in packs of three. Delaney's 3-1/2 x 3-1/2 bulk steel residential hinges are interior residential with a 5/8" radius. The leaf size, the corner radius on some of them, and the residential construction all differ from a 4-1/2 x 4-1/2 square corner commercial prep.
24) What ball bearing commercial hinge fits a 4 inch prep instead of the 4-1/2 inch 5BB1?
The Delaney CH401X is a 4" x 4" commercial ball bearing hinge with square corners, which keeps the ball bearing construction and the square corner of the Ives 5BB1 on a smaller leaf. If the prep is 4" x 4" with a radius corner, the Orca Hardware 4014 Series is a 4" x 4" x 1/4" radius corner commercial hinge, though it is plain bearing rather than ball bearing. Measure the existing mortise before ordering: a 4" hinge will not cover a 4-1/2" cut-out.
25) What is the difference between a 5-knuckle hinge like the 5BB1 and a concealed bearing hinge?
The Ives 5BB1 has five knuckles with the bearings visible in the barrel between them. Concealed bearing peers hide the bearing inside the knuckle and generally use fewer knuckles: the Hager 920 is a full mortise concealed bearing hinge of two knuckle steel construction at medium duty, and the BEST CB1969R is a concealed bearing heavy weight pivot-reinforced hinge at heavy duty. The McKinney SQ3331 is a square barrel two knuckle decorative hinge in 4-1/2 by 4-1/2 at standard duty, which shares the leaf size but presents a very different barrel. Knuckle count changes the look of the barrel on the finished opening, so match it across doors that sit in the same corridor.
26) For a brass or non-ferrous hinge rather than steel, what compares to the 5BB1?
The Ives 5BB1 is offered in brass and stainless steel substrate and in finishes from 606 satin brass and 633 satin brass through 630 satin stainless. The McKinney T2314 is a non ferrous hinge, standard weight, 5 knuckle, at medium duty, which keeps the five knuckle standard weight construction in a non-ferrous base. Among the heavy weight options, the Don-Jo HWBB85045 is a brass heavy weight full mortise ball bearing hinge in 5" x 4-1/2" with a satin chrome finish. Non-ferrous base material is what gets specified for exterior and coastal openings where a steel base would corrode.
27) Where do I get the mortise cutout dimensions and screw hole layout for the Ives 5BB1?
Ives publishes a hinge template index that carries the mortise cutouts and screw hole spacing for the architectural hinge line, and it's what a shop uses to prep a door or verify a frame before ordering. The Ives full line catalog covers the rest of the range. Both are posted with the 5BB1 product information, along with the Allegion Connect data sheet if you're specifying the CON connector version.
