This 5-knuckle hinge features a removable pin for convenient installation and maintenance, with ball bearing mechanism ensuring smooth, quiet operation while reducing friction and wear. The wide throw configuration positions doors further from the frame when open, making it ideal for applications requiring 180° door opening or accommodating door stops and thick weather stripping.

  • 5-Knuckle Configuration: Five knuckle design distributes load evenly across the hinge for enhanced stability and durability.

BEST BEST-FBB179WT-652-4.5x5 – Frequently Asked Questions

1) What does a wide throw hinge like the BEST FBB179WT actually do that a standard hinge won't?
Wide throw means the leaves are wider than a standard hinge, so the door swings further away from the frame as it opens. That extra clearance is what lets a door reach a full 180 degrees when it's set in a reveal, and it's what gets the door past a stop or thick weather stripping instead of binding on it. If your door hits the frame, the trim, or the wall before it lays flat, this is the hinge that fixes it. If your door already opens freely, a standard-throw full mortise hinge is the simpler order.
2) Will the BEST FBB179WT drop into my existing hinge mortise?
It's a full mortise hinge with square corners, so it goes into a routed pocket in both the door edge and the frame, one leaf each side. If what's in your door now is a square corner mortise of the same height, the prep matches. Rounded-corner mortises will not take it without rework. The wide throw only adds width on the open dimension, not to the leaf that sits in the pocket, so the mortise depth and hinge height are what you measure before ordering.
3) I need the door to clear the opening for a wheelchair or a gurney. Is a wide throw hinge the right part?
It depends which problem you have. Wide throw gets the door swung further out of the way, past stops and stripping, up to 180 degrees, but the door leaf still sits in the opening at 90 degrees. If you need the full clear width at 90 degrees, with the door pulled entirely clear of the frame, that's a swing clear hinge, not a wide throw. ZenSupply carries the Hager 1260 full mortise swing clear hinge for that. Healthcare corridors and tight door openings are usually a swing clear job.
4) What is the closest wide throw ball bearing hinge to the BEST FBB179WT if I need a heavier duty version?
The Hager WTBB1168 is the heavy weight counterpart. It is a 4-1/2 inch by 6 inch full mortise ball bearing wide throw hinge with 5 knuckles, so it keeps the same wide throw geometry and 5-knuckle ball bearing build as the FBB179WT, which is a medium duty full mortise ball bearing hinge with 5 knuckles. Use the WTBB1168 where the door weight or traffic calls for a heavy weight hinge, and the FBB179WT where a medium duty standard weight hinge suits the opening. The FBB179WT covers 4-1/2 inch by 6 inch as well, so a direct size-for-size swap is possible at that size.
5) Can I run power through the FBB179WT for an electric lock, or do I need a different hinge?
For a powered opening you need an electric through-wire hinge. The ACSI 5BB1 is an Ives 5 knuckle ball bearing full mortise hinge, 4-1/2 inch by 4-1/2 inch, with concealed electric through-wire in a 4 wire 28 gauge configuration, in the 1100 Series. The FBB179WT is a mechanical full mortise ball bearing hinge with a removable pin and no wiring provision, so on a door with an electrified lock the through-wire hinge takes one position in the hinge set and hinges like the FBB179WT fill the rest.
6) The opening needs the door to clear the frame so a wheelchair can pass. Is the FBB179WT the right hinge, or a swing clear?
Those solve two different clearance problems. The Hager 1260 is a full mortise swing clear hinge with a 5-knuckle plain bearing design, heavy duty; a swing clear hinge swings the door leaf out of the opening so the door thickness is not lost from the clear width. The FBB179WT is a wide throw hinge, meaning wider leaves push the door away from the frame so it can open a full 180 degrees and clear trim, door stops or thick weather stripping. If the goal is recovering clear opening width, the 1260 is the swing clear part; if the goal is swinging the door back flat against the wall, the FBB179WT wide throw is the one.
7) Can I take the door off without unscrewing the hinges?
Yes. The FBB179WT uses a removable pin, so you drive the pin out and lift the door off the frame leaf with the screws left alone. That matters on turnover work and anywhere you pull doors for painting or to move equipment through. It also means the hinge offers no non-removable-pin security, so on an outswing exterior door where the barrel is exposed, spec a security-stud or NRP hinge instead.
8) Ball bearing or plain bearing hinge, which do I need?
Ball bearing, like the FBB179WT, carries the load on races between the knuckles, so the door swings smoothly and stays quiet as the cycles pile up. That's what you want on a door that gets used all day, or one carrying a closer, since a closer keeps loading the hinge on every swing. Plain bearing is the cheaper choice for low-traffic openings with no closer, and ZenSupply carries the Hager 1279 as a medium duty plain bearing full mortise hinge if that's your situation.
9) Is a plain bearing hinge like the Hager 1279 the same thing as the FBB179WT?
No. The Hager 1279 is a full mortise commercial hinge with 5 knuckles at medium duty, but it is a plain bearing design, while the FBB179WT is a ball bearing hinge. Both are medium duty full mortise 5-knuckle hinges, so they can look interchangeable on a spec line. The difference is the bearing: the ball bearing in the FBB179WT is what carries the load with reduced friction on doors under frequent use, and the FBB179WT also carries the wide throw leaf geometry the 1279 does not.
10) How do the McKinney TCA hinges compare to the BEST FBB179WT for a commercial door?
The McKinney TCA2314 and TCA2317 are square corner 5 knuckle full mortise hinges at 4-1/2 inch by 4-1/2 inch, both standard duty, and the McKinney TCA3386 is the same square corner 5 knuckle full mortise size in heavy weight. All three share the FBB179WT's square corner, 5-knuckle, full mortise format, so they drop into standard hinge prep. The difference is leaf width: they are 4-1/2 by 4-1/2, while the FBB179WT is built wide throw in 4-1/2 by 5 inch, 4-1/2 by 6 inch and 4 by 7 inch to hold the door further off the frame.
11) Is the Hager 1541 an acceptable substitute for the FBB179WT on apartment corridor doors?
They are aimed at different service. The Hager 1541 is a full mortise residential hinge with stainless steel construction, 5 knuckle, plain bearing. The FBB179WT is a commercial ball bearing hinge at medium duty, and the ball bearing is what handles repeated cycling on traffic doors. On a corridor or common-area door in a multi-tenant building, the commercial ball bearing hinge is the one to spec; the 1541 suits residential unit doors.
12) I need a 4-1/2 by 4 inch ball bearing hinge in satin chrome. Does the FBB179WT cover that?
The FBB179WT is offered in 652 satin chrome, but in the sizes 4-1/2 by 5 inch, 4-1/2 by 6 inch and 4 by 7 inch. For a 4-1/2 inch by 4 inch leaf in satin chrome, the Don-Jo BB74540 is a full mortise ball bearing hinge in that exact size and finish at standard duty. Note that the BB74540 is a conventional leaf, not wide throw, so it will not hold the door out from the frame the way the FBB179WT does.
13) What finishes does the BEST FBB179WT come in, and how do I match the rest of my building?
Three finishes: 640 satin bronze dark oxidized oil rubbed, 651 bright chromium plated, and 652 satin chromium plated. Those are BHMA finish numbers, so match them to the number on the hardware you already have rather than to the name. 652 satin chrome is the usual match for satin chrome and brushed stainless lever and closer hardware in commercial buildings, 651 is the polished version, and 640 is the dark bronze option. Every finish is available in all three hinge sizes.
14) How many BEST FBB179WT hinges do I need per door?
Standard commercial practice is three hinges on a door up to 7 feet 6 inches tall, and one more for each additional 30 inches of height. The FBB179WT is sold as an individual hinge, so count the openings and multiply. Its 5-knuckle build spreads the load across the barrel, which is what you want when three hinges are carrying a solid core door plus a closer.
