BEST BEST-FBB191-626-3.5x3.5 – Frequently Asked Questions

1) Will the BEST FBB191 hinge work on a hollow metal frame, or is it only for wood doors?
Both. The FBB191 uses template screw hole locations, so the same hinge mounts on wood or hollow metal doors and frames without a different part number. It is a full mortise hinge, meaning both leaves mortise into the door edge and the frame rabbet, so the opening has to be prepped for a mortise hinge on both sides.
2) Is the FBB191 heavy enough for a solid core exterior or high traffic door?
No. The FBB191 is a medium duty, standard weight ball bearing hinge built for medium weight doors of average frequency use. For a heavy door or a high cycle opening, step up to a heavy weight hinge such as the McKinney TCA3386 or the Hager WTBB1168, both heavy duty 5 knuckle full mortise ball bearing hinges.
3) Can I pull the door without unscrewing the BEST FBB191 hinges?
Yes. The FBB191 has a removable pin with a hole in the bottom tip, so you drive the pin up and out and lift the door off the frame leaf. That is the normal way to hang or pull a door for painting or maintenance. Note that a removable pin is not a security pin: on an outswing exterior door where the barrel is on the unsecured side, spec a non-removable pin hinge instead.
4) Ball bearing vs plain bearing hinge, which do I need for a commercial door?
Ball bearing is what you want anywhere the door gets regular use or carries a closer. The FBB191 runs two permanently lubricated non-detachable ball bearings between the knuckles, which carries the door weight and cuts the friction that wears out a plain bearing barrel. A plain bearing hinge is metal on metal in the knuckle and suits low traffic openings; if that is your situation, the Hager 1279 is a medium duty 5 knuckle plain bearing commercial hinge and the Hager 1541 is the plain bearing residential version.
5) Will the FBB191 match the square corner hinge mortises already cut in my frames?
Square corner, yes. The FBB191 is a square corner hinge, so it drops into an existing square corner mortise of the same leaf size, which is the standard prep on hollow metal frames. If your wood doors were routed with a radius corner router bit, a square corner leaf will not seat without recutting the corners.
6) Can I replace one worn Don-Jo BB74545 hinge with a BEST FBB191?
Size for size, yes. The Don-Jo BB74545 is a 4-1/2 x 4-1/2 square corner 5 knuckle full mortise ball bearing hinge, and the FBB191 is offered in 4-1/2 x 4-1/2 with square corners and 5 knuckles, so it fits the same mortise and template hole pattern. Match the finish code, and be aware the Don-Jo BB74545 is a steel hinge while the FBB191 is brass, bronze or stainless, so plated appearance can differ slightly on a mixed opening. If you want to stay in steel-bodied Don-Jo, the BB84545 is brass and the BB94545 stainless steel in the same size.
7) Can the BEST FBB191 be used where an ADA opening needs the full clear width of the doorway?
No. A standard full mortise hinge like the FBB191 leaves the door edge in the opening when the door swings back. For that condition use the Hager 1260 full mortise swing clear hinge, a heavy duty five knuckle design that carries the door clear of the opening to recover clear width. Note the 1260 is a plain bearing hinge, where the FBB191 is ball bearing, so it is a different bearing specification and not a like for like swap on anything but geometry.
8) The FBB191 is rated medium duty - what ball bearing hinge should be used on a heavy door or a high traffic entrance?
Step up to a heavy duty hinge. The McKinney TCA3386 is a heavy duty square corner five knuckle full mortise hinge in 4-1/2 by 4-1/2, which matches one of the sizes the FBB191 is offered in, so the frame prep carries over. For concealed bearing construction at heavy weight, the Dormakaba CB199 full mortise concealed bearing heavy weight hinge is the heavy duty member of the same Architectural Hinges series the FBB191 belongs to. Both are the right call where the FBB191 medium duty rating falls short of the door weight or traffic frequency.
9) What hinge should be used instead of the FBB191 when the door has to clear deep trim or a thick wall return?
Use a wide throw hinge. The Hager WTBB1168 is a 4-1/2 by 6 inch full mortise ball bearing wide throw hinge, heavy weight with five knuckles. The extra leaf width throws the door further off the frame so it clears projecting casing or a deep reveal. The FBB191 is offered in leaf sizes from 3-1/2 by 3-1/2 up to 5 by 5, none of which provide that throw, so where the reveal is the problem the wide throw hinge is the part to order.
10) Do I have to order the FBB191 hinge in left hand or right hand?
No handing to specify. The flush tips and pins on the FBB191 are reversible, so one hinge serves either hand. Order by size and finish only.
11) What finishes does the BEST FBB191 hinge come in, and which one matches my other door hardware?
Eight finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil rubbed, 625 bright chrome, 626 satin chrome, 629 bright stainless steel and 630 satin stainless steel. Those are BHMA finish numbers, so match the number stamped on the levers or closers already in the building rather than the finish name. 630 satin stainless is the usual commercial default; 626 satin chrome is the common match to satin chrome locksets.
12) Are BEST FBB191 hinges stainless steel or brass?
Depends on the finish you order. The FBB191 is made in brass, bronze or stainless steel, and the finish code tells you the base material: 629 and 630 are stainless steel, the 605/606 brass and 612/613 bronze finishes are non-ferrous. Non-ferrous hinges get stainless steel pins. For a coastal or wash down opening, order a stainless variant.
13) How many hinges do I need per door with the FBB191?
Standard commercial practice is three hinges on a door up to 7 feet 6 inches tall, adding one more for each additional 30 inches of height. Because the FBB191 is a medium duty hinge, do not try to save a hinge on a heavier leaf, add the third and fourth rather than pushing two beyond the medium weight rating. All hinges on the opening should be the same size and finish so the mortises and the look stay consistent.
14) My door has heavy trim or a deep frame and hits the wall when it opens. Is the FBB191 the right hinge?
Probably not. The FBB191 comes in standard leaf widths (3.5, 4, 4.5 and 5 inch open widths), which set the door back at a normal pivot point. When trim, a wrap or a thick frame stops the door short, you need a wide throw hinge that pushes the pivot further out. The Hager WTBB1168 is a 4-1/2 x 6 inch full mortise ball bearing wide throw hinge, heavy weight with 5 knuckles.
15) What is a simpler steel ball bearing hinge to standardize on across a building instead of the BEST FBB191?
The Don-Jo BB74545 is a standard duty full mortise ball bearing hinge, 4-1/2 by 4-1/2, in steel with square corners and five knuckles. It matches the FBB191 on corner style, knuckle count and one of its stock sizes, so the door and frame prep is the same, and it steps the duty rating down from the medium duty FBB191 to standard duty. For the 4-1/2 by 4 opening the Don-Jo BB74540 covers the same ground in satin chrome, a finish the FBB191 also offers as 626 satin chrome.
16) The FBB191 comes in stainless steel finishes - what is the alternative if the hinge body itself needs to be stainless for a wet or coastal opening?
The Don-Jo BB94545 is a stainless steel full mortise ball bearing hinge, 4-1/2 by 4-1/2, with square corners, and it is rated standard duty. The FBB191 is also built in stainless steel among its brass and bronze options, with stainless steel pins used in the non-ferrous hinges, and it offers 629 bright stainless steel and 630 satin stainless steel finishes at medium duty. Match the base material to the environment first, then pick the duty rating the door needs.
17) How does the BEST FBB191 compare to the McKinney TCA2314 and TCA2317 for a commercial door?
The McKinney TCA2314 and TCA2317 are both square corner five knuckle full mortise hinges in 4-1/2 by 4-1/2, rated standard duty. The FBB191 shares the square corner, five knuckle full mortise construction and offers a 4-1/2 by 4-1/2 size, so all three prep the same, but the FBB191 is rated medium duty and specifies ball bearing operation with a removable pin for taking the door down without disturbing the frame leaf. Choose on the duty rating the opening calls for and on whether the pin needs to come out for service.
18) Is a residential hinge like the Hager 1541 acceptable in place of the BEST FBB191 on a commercial door?
No. The Hager 1541 is a full mortise residential hinge with stainless steel construction and a five knuckle plain bearing design. The FBB191 is specified for commercial use, medium duty, with ball bearing operation for medium weight doors of average frequency use in commercial and institutional buildings. On a commercial opening that sees regular traffic or carries a closer, the ball bearing commercial hinge is the correct part and the residential plain bearing hinge is not an equivalent.
19) What is the difference between the BEST FBB191 and the Don-Jo BB84545 brass hinge?
The Don-Jo BB84545 is a brass full mortise ball bearing hinge, 4-1/2 by 4-1/2, finished in satin chrome and rated standard duty. The FBB191 is also built in brass among its material options and offers a 4-1/2 by 4-1/2 size along with 626 satin chrome, but it is rated medium duty and its pin is removable with a hole in the bottom tip for pulling the pin during door hanging or removal. The two share base material, size and finish; they differ in duty rating and in pin serviceability.
