Ives 5BB1SC 4.5 652 – Frequently Asked Questions

1) Can I use the Ives 5BB1 swing clear hinge on a door with a closer on it?
Yes, and that is exactly what it is built for. The 5BB1 SC/BSC carries dual ball bearing assemblies, and Ives specifically recommends it for doors fitted with closers. Closers put constant load on the knuckles, and plain bearing hinges wear and start binding under that. If you are hanging a door with a closer, do not substitute a plain bearing hinge to save a few dollars.
2) Do I need square edge or bevel edge hinges, and what happens if I order the wrong one?
The 5BB1 SC/BSC comes both ways, square edged and bevel edged, and it has to match the edge of the door you are hanging. Wood doors are commonly beveled on the lock edge and sometimes the hinge edge; hollow metal doors are typically square. Pull the old hinge or lay a square on the hinge edge before you order. Getting it wrong shows up as a leaf that does not sit flat in the mortise and a door that binds against the frame.
3) What grade is the Ives 5BB1 swing clear hinge certified to, and how many cycles?
BHMA Grade 2 under ANSI/BHMA A156.1, with a 1,500,000 cycle rating. It is also UL Classified for windstorm rated assemblies under R37965. For institutional and government spec work where the drawing calls out a certified hinge, those are the numbers to write down. Note it is Grade 2 rather than Grade 1, so if the spec explicitly demands Grade 1 heavy weight, this is not the hinge.
4) Can I run power through the door with an Ives 5BB1 hinge for an electric strike or electrified lock?
Electrified versions of the 5BB1 are available: TW4, TW8, TW12 through-wire configurations plus monitor options that report door position. TW4 handles a simple electrified lock, TW8 and TW12 cover locks with request-to-exit and status monitoring. These are factory-built options, not a field conversion, so the wire count has to be specified on the order. If you need a heavier duty energy transfer hinge, the Command Access ETH-BB68 is a heavy duty 5-knuckle energy transfer hinge, and the ETM-BB68 is the heavy duty version with an integrated door position switch.
5) I don't need the swing clear feature, I just need a commercial ball bearing hinge. What else could I buy?
Swing clear costs extra and only pays off when you are fighting for clear width, so if the opening is fine, a standard full mortise ball bearing hinge does the job. Orca's COM3535 is a 4-1/2 x 4-1/2 inch square corner ball bearing commercial hinge in medium duty, the same duty class as the 5BB1 SC/BSC. If the door is heavy or high traffic, Don-Jo's HWBB74545 is a heavy duty 4-1/2 x 4-1/2 inch full mortise ball bearing hinge, and the HWBB75045 is the 5 x 4-1/2 inch heavy duty version.
6) The door is heavier than 150 lbs. What ball bearing mortise hinge should be used instead of the Ives 5BB1 SC/BSC?
The Ives 5BB1 SC/BSC is rated medium duty for doors up to 150 lbs at up to 400 cycles per day. Above that weight, step to a heavy duty ball bearing full mortise hinge: the Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge at 4-1/2 inch by 4-1/2 inch, and the Don-Jo HWBB85045 is the same heavy weight ball bearing build at 5 inch by 4-1/2 inch. The Hager BB1168 is another heavy duty full mortise ball bearing hinge and comes with a non-removable pin for out-swinging exterior openings. None of these are swing clear, so the door leaf will still sit in the opening when the door is open.
7) What is the closest ball bearing full mortise hinge to the Ives 5BB1 SC/BSC if a swing clear leaf is not needed?
The Ives 5BB1 SC/BSC is a 5-knuckle ball bearing full mortise hinge in medium duty, and its swing clear wide throw leaf exists to pull the door fully out of the opening for clearance. On an opening that does not need that clearance, the Orca Hardware 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge rated medium duty, which matches the bearing type, the commercial rating, and the duty level of the 5BB1 SC/BSC with a conventional flat leaf. The Ives runs 4-1/2 by 4-1/2 and 5 by 5, so the Orca covers the smaller of the two sizes.
8) Can a plain bearing commercial hinge be used in place of the Ives 5BB1 SC/BSC?
The Ives 5BB1 SC/BSC uses dual ball bearing assemblies and is specifically recommended for openings with a door closer, where the closer load runs through the hinge every cycle. Plain bearing hinges such as the Orca Hardware 4040 Series 4 inch by 4 inch square corner commercial hinge and the Orca 4014 Series 4 inch by 4 inch quarter inch radius corner commercial hinge are both medium duty commercial hinges, but they are plain bearing rather than ball bearing. On a closered opening at 400 cycles per day, match the bearing type of the 5BB1 SC/BSC rather than substituting a plain bearing unit.
9) What is the difference between the Ives 5BB1 SC/BSC and a standard weight 5-knuckle mortise hinge like the Stanley FBB191 or McKinney MP79?
The Ives 5BB1 SC/BSC is a swing clear wide throw hinge: the leaf geometry carries the door clear of the frame so the full opening width is usable, which is why it is specified on accessibility openings. The Stanley FBB191 is a 5-knuckle full mortise standard weight hinge at 4.5 inch by 4.5 inch and the McKinney MP79 MacPro is a 5-knuckle full mortise standard weight hinge, both conventional flat-leaf hinges with the same 5-knuckle full mortise format but no swing clear throw. If clear opening width is what drove the specification, the swing clear geometry of the 5BB1 SC/BSC is the reason to keep it.
10) The existing doors have radius corner hinges. Does the Ives 5BB1 SC/BSC match, and what does if it does not?
The Ives 5BB1 SC/BSC has square corners across its 4-1/2 inch by 4-1/2 inch and 5 inch by 5 inch sizes, in bevel edged and square edged versions. Doors mortised for radius corners need a radius corner hinge instead: the Orca Hardware 4014 Series is a 4 inch by 4 inch commercial hinge with a 1/4 inch radius corner and the Orca 3514 Series is a 3-1/2 inch by 3-1/2 inch commercial hinge with a 1/4 inch radius corner, both medium duty and both plain bearing. The Delaney RH45xx is a 4 inch by 4 inch exterior residential hinge with a 5/8 inch radius, a different radius profile again, so confirm which radius the existing mortise was cut to before ordering.
11) Are the mounting screws included with the Ives 5BB1 hinge, or do I have to buy them separately?
Both sets come in the box. You get 12-24 x 1/2 inch undercut flat head machine screws for the hollow metal side and 12 x 1-1/4 inch flat head wood screws for wood doors and wood frames, so a wood door hung in a hollow metal frame is covered without a separate fastener order. Security fasteners are a factory option if the opening needs them.
12) Which finishes does the Ives 5BB1 SC/BSC come in, and does the base metal change with the finish?
Twelve finishes are offered: 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. Substrate is 1040 steel for the standard finishes; the 630 satin stainless finish is built on a 304 stainless base instead. For a wet or coastal opening, stainless is the substrate to ask for. Property managers matching a building standard usually land on 652 satin chrome, which is the common commercial default.
13) What options should I specify on an Ives 5BB1 order for a hospital or a psychiatric unit?
Hospital tip is the option to call out. It closes off the top and bottom of the barrel so nothing can be looped over the hinge, which is why behavioral health and detention-adjacent openings ask for it. Non-removable pin (NRP) is the one to add on any out-swinging exterior door, since it stops the pin being driven out from the unsecured side. Security studs and security fasteners are also available, along with rounded corners if the door prep is radiused rather than square. Standard corner style on the 5BB1 SC/BSC is square.
14) My door prep has radius corners, not square. Can I still use the Ives 5BB1 swing clear hinge?
The 5BB1 SC/BSC ships square cornered as standard, but rounded corners are a factory option, so it can be ordered to suit a radiused prep. If you would rather buy off the shelf, Deltana's DE44R5TA is a 4 x 4 inch steel hinge with a 5/8 inch radius, and Orca's COM4014 is a 4 x 4 inch with a 1/4 inch radius corner. Match the radius to the prep, since a 5/8 inch corner will not seat in a 1/4 inch routed pocket.
15) Can I swap an Ives 5BB1 swing clear hinge into the existing prep on my door, or does it need new routing?
Swing clear hinges use a different leaf geometry from a standard mortise hinge, so a straight drop-in is not something to assume. The 5BB1 SC/BSC is a full mortise hinge, meaning both leaves mortise into the door edge and the frame rabbet. Pull one existing hinge, confirm the pocket size against the 4-1/2 x 4-1/2 or 5 x 5 inch leaf and confirm the edge is square or beveled to match, then work off the Ives hinge templates before you cut anything.
16) Which hinge carries power to an electrified lock, since the Ives 5BB1 SC/BSC lists electrification options?
The Ives 5BB1 SC/BSC is offered with TW4, TW8, TW12 and monitor electrification options on a 5-knuckle ball bearing swing clear body. Where the opening does not require swing clear, purpose-built transfer hinges cover the same job: the Command Access ETH-BB68 is a 5-knuckle heavy duty steel base energy transfer hinge, the ETH-CB70 is a 3-knuckle standard weight medium duty energy transfer hinge, and the BEST CECB179-12C is a medium duty steel full mortise concealed bearing electrified hinge with a 12-wire quick connect. For door position monitoring rather than power transfer alone, the Command Access ETM-BB68 adds an integrated door position switch and the ETM-CB70 adds door position sensing on a 3-knuckle steel base.
17) Is a concealed bearing hinge an alternative to the Ives 5BB1 SC/BSC?
The Ives 5BB1 SC/BSC is a 5-knuckle hinge with visible dual ball bearings between the knuckles. Concealed bearing hinges hide the bearing inside the barrel for a cleaner knuckle line: the Hager 920 is a full mortise concealed bearing hinge with 2-knuckle steel construction rated medium duty, and the BEST CB1969R is a concealed bearing heavy weight pivot-reinforced hinge in heavy duty. The Hager 920 matches the medium duty level of the 5BB1 SC/BSC but changes the knuckle count from 5 to 2, so the door and frame prep and the visible barrel appearance both change.
18) The Ives 5BB1 SC/BSC is offered with security studs and non-removable pin. What other hinges cover a security opening?
The Ives 5BB1 SC/BSC lists hospital tip, non-removable pin, security studs and security fasteners as options on its swing clear ball bearing body. Where a higher security build is called for, the Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge, and the Deltana DE44R5TA is a 4 inch by 4 inch security hinge with a 5/8 inch radius corner in steel, sold as a pair. For detention work the BEST BB855 is a heavy duty steel double weight concealed ball bearing prison hinge and the Hager 990 STEEL is a 3 inch by 4 inch full surface prison hinge with a welded tip, both a different class of opening than the commercial doors the 5BB1 SC/BSC covers.
19) Does the Ives 5BB1 SC/BSC close the door on its own like a spring hinge?
No. The Ives 5BB1 SC/BSC is a ball bearing swing clear hinge that is specifically recommended for use with a door closer, meaning the closing force comes from a separate closer rather than the hinge. A spring hinge such as the Stanley Security 2060R at 4.5 inch by 4.5 inch is a full mortise square corner spring hinge in heavy duty that provides its own closing action. The two are not interchangeable: the 5BB1 SC/BSC carries the door and the closer load, and the 2060R supplies closing force but does not offer the swing clear throw.
20) Is a pivot the right substitute for the Ives 5BB1 SC/BSC when clear opening width matters?
The Ives 5BB1 SC/BSC gets its clearance from a swing clear wide throw leaf while remaining a full mortise hinge, so the door and frame keep standard hinge prep. A pivot is a different hanging method entirely: the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors, which swings the door both directions from a top and bottom pivot point rather than from a hinge edge. If the door prep is already cut for full mortise hinges, the 5BB1 SC/BSC keeps that prep; a pivot changes how the door hangs and what has to be prepared at the head and floor.
21) What is a non-ferrous alternative when the Ives 5BB1 SC/BSC steel base is not suitable?
The Ives 5BB1 SC/BSC is built on a steel or stainless steel substrate, with stainless used for the 630 finish. In an environment where a ferrous base is not wanted, the McKinney T2314 is a non-ferrous hinge in standard weight with 5 knuckles and a medium duty rating, matching the 5-knuckle format and the medium duty level of the 5BB1 SC/BSC on a non-ferrous base. It is not a swing clear hinge, so clear opening width would be given up in the swap.
22) Is a 5-knuckle hinge better than a 3-knuckle for a commercial door?
Knuckle count spreads the load. The 5BB1 SC/BSC is a 5-knuckle hinge with ball bearings between the knuckles, which is the standard commercial build for a door carrying a closer. Three knuckle hinges are typically standard weight and show up on lighter doors; Command Access's ETH-CB70, for example, is a 3-knuckle medium duty energy transfer hinge. For a 150 lb door running 400 cycles a day, the 5-knuckle is the right build.
23) Can I use the Ives 5BB1 SC/BSC on interior residential doors in my apartment buildings?
It will work, but it is overspecified for an interior residential door. The 5BB1 SC/BSC is a commercial rated hinge for doors up to 150 lbs at 400 cycles a day. For interior unit doors in a multi-family building, Delaney's RH35xx is a 3-1/2 x 3-1/2 inch bulk steel residential interior hinge sold in pairs with a 5/8 inch radius, and the RH45xx is the 4 x 4 inch bulk exterior version. Keep the 5BB1 SC/BSC for corridor and entry doors where the closer and the clear width actually matter.
