BEST BEST-FBB168WT-652-4.5x5 – Frequently Asked Questions

1) What does a wide throw hinge like the BEST FBB168WT actually do that a standard hinge doesn't?
Wide throw means the leaves are wider than normal, so the door swings out further from the frame when open. That's what you use when a door sits in a deep reveal and has to clear the trim or wall to reach a full 180 degrees. On a flush frame with no reveal, a standard-width hinge is the correct part; the extra throw just pushes the door out where you don't need it.
2) What size and finish does the BEST FBB168WT wide throw hinge come in?
The FBB168WT is sold in 4-1/2 by 5 inches, finish 652 satin chrome over steel. The 5 inch leaf dimension is the wide throw part, paired to the standard 4-1/2 inch height, so it drops into a normal 4-1/2 inch hinge height on the door edge while throwing the door further out.
3) Is the FBB168WT hinge heavy enough for a solid core or metal commercial door?
It's rated heavy duty and built for commercial use, with ball bearings and a 5-knuckle steel body. Ball bearings are what carry a heavy or high-traffic leaf without the knuckles wearing oval, which is why plain bearing hinges get spec'd on light interior doors and ball bearing ones on entrances and stairwells.
4) Will a square corner hinge fit my existing door mortise?
The FBB168WT has square corners, so it needs a mortise cut square, the standard prep on hollow metal frames and commercially machined doors. If your existing pockets are round cornered (typical of a router-cut wood door done with a hinge template), a square corner leaf will not seat without chiseling the corners out. Check the pocket before you order.
5) I don't need wide throw, just a heavy duty 4-1/2 x 4-1/2 hinge. What should I order instead?
Go to a standard-width heavy weight hinge. The McKinney TCA3386 is a square corner, 5 knuckle, full mortise heavy weight in 4-1/2 by 4-1/2. The Dormakaba CB199 is another heavy weight full mortise option, using concealed bearings rather than exposed ball bearings, which some architects prefer for the cleaner barrel. Ordering the FBB168WT for a flush frame just holds the door further off the jamb than the opening needs.
6) My door hits the wall or trim before it opens all the way. Is a wide throw hinge the fix?
That's exactly the case it's built for. A door set back in a reveal binds on the casing or the return wall long before 180 degrees, and moving the pivot point outboard with a wider leaf clears it. If instead your problem is clear opening width, a wheelchair gurney passing the hinge barrel, then a swing clear hinge is the right type, not wide throw. The Hager 1260 is a full mortise swing clear hinge, though it's plain bearing rather than ball bearing.
7) Can I run power through the FBB168WT to an electrified lock?
No. The FBB168WT is a mechanical hinge with a removable pin and no wire path. When the opening needs power transferred to an electric strike, mag lock, or electrified lockset, the ACSI 5BB1 is a 5 knuckle ball bearing full mortise hinge at 4-1/2 by 4-1/2 with a concealed electric through-wire, 4 wire at 28 gauge. It carries the current inside the barrel so no surface loop is needed. Plan the wire run through the frame before the mortise is cut.
8) Will a swing clear hinge do the same job as the FBB168WT?
They solve different problems and are not interchangeable. The Hager 1260 is a full mortise swing clear hinge with a 5 knuckle plain bearing design, heavy duty; a swing clear leaf moves the door out of the doorway opening so the full clear width is available, which is an accessibility move. The FBB168WT is a wide throw ball bearing hinge whose wider leaves push the door further out when open so it clears a reveal and reaches 180 degrees. Note also the bearing: the 1260 is plain bearing, the FBB168WT is ball bearing.
9) Can I take the door down without unscrewing the hinges?
Yes. The FBB168WT uses a removable pin, so you drive the pin out and lift the leaf off the frame with both mortised leaves still fastened. Note that a removable pin is not a security pin: on an out-swinging exterior door where the hinge barrel is on the outside, you want a non-removable pin or a set screw hinge instead.
10) Is this a full mortise hinge or a half mortise? What prep does it need?
Full mortise: both leaves are let into pockets, one in the door edge and one in the frame rabbet, so nothing shows but the barrel when the door is closed. Half mortise and half surface hinges mortise only one leaf and surface-apply the other, which is what you use on channel iron frames or doors that can't be routed. If your frame isn't prepped for a mortised leaf, this isn't the hinge.
11) Can I use a cheaper standard duty ball bearing hinge on a commercial door instead?
Only on lighter, lower-traffic leaves. The Don-Jo BB74545 (steel, square corner, 5 knuckle, 4-1/2 by 4-1/2) and the McKinney TCA2314 are standard duty ball bearing hinges. Standard duty is fine for an interior office door; on a heavy solid core, a lead-lined door, or a stairwell that cycles all day, stay with a heavy weight hinge like the FBB168WT. Neither of those standard duty options is wide throw, so they will not solve a reveal clearance problem either.
12) Will the FBB168WT hinge rust on an exterior or wet location door?
It's steel with a 652 satin chrome finish, which is a plated steel finish meant for interior commercial openings. For a pool room, a kitchen, a car wash, or a coastal exterior, move to stainless. The Don-Jo BB94545 is a stainless steel full mortise ball bearing hinge with square corners in 4-1/2 by 4-1/2, though it is standard duty and standard width, not wide throw.
13) How many wide throw hinges do I need per door, and do I have to match the others on the opening?
Standard commercial practice is three hinges on a door up to 7 feet 6 inches tall and a fourth above that, all the same size, throw, and finish on a given leaf. Mixing a 5 inch wide throw with standard 4-1/2 by 4-1/2 hinges on the same door will bind the swing. If you're standardizing a building, order the full set per opening in 652 satin chrome so the barrels match.
14) Does a wide throw hinge get handed, or is one part good for left and right doors?
A full mortise ball bearing hinge with a removable pin is non-handed, so the same part works on a left or right hand door. What does matter is which side the barrel ends up on: on an out-swing, the barrel and its removable pin sit on the unsecured face, so spec a security stud or non-removable pin hinge for exterior out-swing openings.
15) What is the difference between the FBB168WT and a concealed bearing hinge like the CB199?
The bearing is exposed on one and hidden on the other. The FBB168WT carries a ball bearing barrel between the knuckles, rated heavy duty with a removable pin. The Stanley Security CB199 is a full mortise concealed bearing heavy weight hinge, also heavy duty and in the same Architectural Hinges series, where the bearing sits inside the knuckle for a smoother barrel line. If the specification calls out a wide throw for reveal clearance, the CB199 does not cover that requirement.
16) The door is a light interior leaf, not a heavy commercial slab. What is a lighter alternative?
Step down in weight class rather than matching the FBB168WT, which is a heavy duty commercial hinge. The Stanley Security CB1960R is a full mortise concealed bearing standard weight hinge, medium duty, in the same Architectural Hinges series. The Hager 1279 is a full mortise plain bearing commercial hinge with 5 knuckles, medium duty. For a lower traffic leaf, the Don-Jo BB74540 is a 4-1/2 by 4 inch full mortise ball bearing hinge in satin chrome, standard duty.
17) I need a hinge that resists corrosion on an exterior or washdown opening. What are my options against the steel FBB168WT?
The FBB168WT is a steel hinge in satin chrome, 652. Where the base material matters, the Don-Jo BB94545 is a 4-1/2 by 4-1/2 full mortise ball bearing hinge in stainless steel with a square corner, and the Don-Jo BB84545 is the same 4-1/2 by 4-1/2 full mortise ball bearing size in brass finished satin chrome. Both are rated standard duty, so confirm the door weight and traffic before swapping off a heavy duty part.
18) Is a plain bearing hinge an acceptable substitute for the ball bearing FBB168WT?
It changes how the barrel carries load. The FBB168WT uses a ball bearing barrel, which is what keeps a heavy leaf swinging smoothly under repeated cycles. Plain bearing peers include the Hager 1279, a 5 knuckle full mortise commercial hinge rated medium duty, and the Hager 1541, a 5 knuckle full mortise residential hinge in stainless steel. Where a drawing calls out ball bearing for a heavy or high cycle door, a plain bearing hinge does not satisfy that call.
19) I am standardizing a building on 4-1/2 by 4-1/2 square corner hinges. Which parts hold that size?
Several peers are catalogued at that exact size with square corners and a 5 knuckle barrel: the McKinney TCA2314 and TCA2317, both standard duty, and the McKinney TCA3386 in heavy weight. The Don-Jo BB74545 is 4-1/2 by 4-1/2 steel, square corner, 5 knuckle, standard duty, and the Don-Jo BB94545 is the same size in stainless steel with a square corner. The FBB168WT is a square corner hinge as well, in 4.5 by 5 inches, so the wide throw openings will not share a mortise with the 4-1/2 by 4-1/2 stock.
