BEST BEST-FBB168-652-4.5x4.5 – Frequently Asked Questions

1) Will the BEST FBB168 hinge work on a heavy commercial entrance door that gets constant traffic?
That is exactly the duty this hinge is built for. The FBB168 is a heavy duty, commercial-rated full mortise hinge running four permanently lubricated, non-detachable ball bearings, so it carries the weight of a heavy door without the knuckle wear and squeak you get from a plain bearing under high cycle counts. Office building and retail entrances, public building doors, and school corridor doors are the intended applications.
2) What sizes does the BEST FBB168 ball bearing hinge come in?
Six sizes: 4.5 x 4, 4.5 x 4.5, 4.5 x 5, 5 x 5, 6 x 5, and 6 x 6 inches. The first figure is the hinge height along the knuckle, the second the open width across both leaves. On standard 1-3/4 inch commercial doors 4-1/2 inch height is the usual pick; the wider open widths (5 inch and 6 inch) are what you move to when thicker trim or a deeper reveal means the door has to clear the frame or wall on the swing.
3) Can you take a door off its hinges with the FBB168 without unscrewing the leaves?
Yes. The FBB168 uses a removable pin in a 5-knuckle barrel, so you pull the pin and lift the door off with the leaves still fastened to the door and frame. That matters for maintenance access and for moving equipment or furniture through an opening. Note that a removable pin on an outswing exterior door is accessible from the secure side unless you order the hinge with security studs, which BEST offers as an option on this hinge.
4) Does the BEST FBB168 hinge fit a square corner mortise, or do I need radius corners?
Square corners. The FBB168 leaf is cut square, which is the standard prep on hollow metal frames and most commercial wood doors. If your existing door and frame were routed with a radiused corner (common on residential-style prepped wood doors), a square corner leaf will not drop into that mortise without recutting the corners, so match the prep you already have.
5) Can I run power through the door for an electric lock using a BEST FBB168 hinge?
Yes, the FBB168 is available with concealed electric wires or switches, ordered with the CE or CS option, which is how you get power from the frame to a door-mounted electric strike, electrified lock, or exit device without a surface loop. That is an option you specify at order time, not something you add to a standard hinge afterward. If you would rather stay with an Ives-style prep, ZenSupply also stocks the ACSI 5BB1, a 4-1/2 x 4-1/2 five knuckle ball bearing full mortise hinge with a concealed 4-wire 28ga through-wire.
6) Do I need a ball bearing hinge, or will a plain bearing hinge do the job?
It comes down to door weight and cycle count. A ball bearing hinge like the FBB168 carries a heavy door on lubricated bearings and stays quiet through constant use, which is why it belongs on entrances and corridor doors. Plain bearing hinges are the cheaper choice for lighter doors and lower traffic, and ZenSupply carries them: the Hager 1279 is a medium duty five knuckle plain bearing commercial hinge, and the Hager 1541 is a stainless steel five knuckle plain bearing hinge for residential work. Where a door closer is fitted or the door is solid core and heavy, stay with ball bearing.
7) I only need hinges for interior office doors, not entrances. Is the FBB168 more hinge than I need?
Probably, yes. The FBB168 is a heavy duty hinge sized for heavy doors on high traffic openings. For ordinary interior doors, ZenSupply stocks standard duty ball bearing full mortise hinges that do the same job for less: the Don-Jo BB74545 in steel with a square corner five knuckle leaf at 4-1/2 x 4-1/2, the BB74540 at 4-1/2 x 4 in satin chrome, or the McKinney TCA2314 and TCA2317 at 4-1/2 x 4-1/2. Keep the FBB168 for the entrances and standardize the interiors on a standard duty hinge.
8) The door has to swing back flat against the corridor wall. Will a standard FBB168 work?
Not always. A standard hinge sets the pin close to the door face, so heavy trim, a deep reveal, or a wall return can stop the door short. Two ways to solve it with this hinge: order the raised barrel (RB) option, which pushes the barrel out from the leaf for clearance, or move up to a wider open width, since the FBB168 runs from 4 inch through 6 inch open width. If you need a true wide throw, ZenSupply also stocks the Hager WTBB1168, a 4-1/2 x 6 inch heavy weight full mortise ball bearing wide throw hinge with five knuckles.
9) What is the closest heavy duty ball bearing full mortise hinge to the BEST FBB168 if I need it in 4-1/2 by 4-1/2?
The McKinney TCA3386 is a square corner, 5 knuckle full mortise hinge in 4-1/2 by 4-1/2 rated heavy duty, the same duty level as the FBB168, which is a heavy duty full mortise ball bearing hinge with square corners and a 5 knuckle barrel. Both cover a 4-1/2 by 4-1/2 opening prep; the FBB168 also runs 4-1/2 x 4, 4-1/2 x 5, 5 x 5, 6 x 5 and 6 x 6, so if a door schedule mixes leaf sizes the FBB168 range covers more of it from one model.
10) Do I need a heavy duty ball bearing hinge on a standard interior office door, or is there a lighter option?
For a lighter door that does not see entrance-level traffic, the Don-Jo BB74545 is a steel full mortise ball bearing hinge in 4-1/2 by 4-1/2 with square corners and 5 knuckles at a standard duty level, and the Don-Jo BB74540 covers the same standard duty in 4-1/2 by 4. The BEST FBB168 is heavy duty and built for high frequency commercial openings such as entrance doors to office buildings, stores and public buildings. All three are full mortise ball bearing hinges, so the door and frame prep concept is the same; the difference is the duty level you are specifying to.
11) What hinge do I use when the door has to clear the opening completely for a wheelchair or gurney?
The Hager 1260 is a full mortise swing clear hinge with a 5 knuckle plain bearing design at a heavy duty level. A swing clear hinge carries the door out of the clear opening when it is open, which a conventional full mortise hinge such as the BEST FBB168 does not do. The FBB168 is a standard full mortise ball bearing hinge for heavy doors and high frequency openings, so on an opening where clear width is the governing requirement the swing clear geometry is the one to specify.
12) The door has to clear a deep trim or wall projection when it opens. Is the FBB168 the right hinge?
For that condition the Hager WTBB1168 is a 4-1/2 by 6 full mortise ball bearing wide throw hinge, heavy weight with 5 knuckles. The wide throw leaf sets the door further off the frame so it clears an obstruction on swing. The BEST FBB168 is a heavy duty full mortise ball bearing hinge with 5 knuckles in sizes from 4-1/2 x 4 up to 6 x 6, which are conventional leaf proportions rather than wide throw. Both are heavy duty ball bearing hinges; the leaf width is what separates them.
13) I need to run power through the hinge to an electrified lock. Can I use the FBB168?
The ACSI 5BB1 is an Ives 5 knuckle ball bearing full mortise hinge, 4-1/2 by 4-1/2, with a concealed electric through-wire in a 4 wire 28 gauge configuration, built for transferring power from frame to door. The BEST FBB168 is a full mortise ball bearing hinge with a removable pin and 5 knuckle barrel, and it is offered with electric wire and switch options among its variations, so confirm the electric option code on the order rather than assuming a standard FBB168 leaf carries the transfer.
14) What other options can I specify on the BEST FBB168 besides finish and size?
Beyond the ten finishes and six sizes, the FBB168 can be ordered with a raised barrel (RB) where the door has to clear a deep frame or a wall return, hospital tips (HT) which take the flat top off the barrel so gowns, IV lines and bedding cannot catch, decorative tips for finished spaces, security studs for outswing doors, and concealed electric wires or switches (CE/CS). Sort those out before the order goes in, since none of them are field-added.
15) What finishes does the BEST FBB168 hinge come in, and which one matches painted hollow metal frames?
Ten: 600 primed for painting, 632 bright brass, 633 satin brass, 639 satin bronze, 640 satin bronze dark, 641 oxidized bronze, 646 satin nickel, 651 bright chrome, 652 satin chrome, and 693 black. For a painted hollow metal frame, 600 is the one to order, since it arrives primed and takes the same paint as the frame. For matching existing commercial lever and closer hardware in a building, 652 satin chrome and 646 satin nickel are the common standard.
16) Which hinge should I use on patient room doors in a hospital?
For heavy healthcare doors the FBB168 works, and the option that matters there is hospital tips (HT). Those replace the flat button tips with a sloped tip so bedding, gowns, IV tubing and cart handles cannot hook the top of the barrel. It is an ordering option on the hinge, so specify HT with the finish and size. If the requirement is instead getting full clear width for a bed or wheelchair through the opening, a swing clear hinge is the different animal you want, and ZenSupply stocks the Hager 1260 heavy duty full mortise swing clear hinge.
17) Is the BEST FBB168 hinge steel or stainless steel, and does that matter for exterior doors?
Steel. The FBB168 is a steel hinge with a plated or primed finish over it, which is right for interior openings and protected exterior entrances. On a door taking direct weather or coastal salt air, stainless is the material that holds up, and ZenSupply carries the Don-Jo BB94545, a stainless steel full mortise ball bearing hinge, 4-1/2 x 4-1/2, square corner. There is also a brass-body option in the Don-Jo BB84545 at the same size in satin chrome.
18) Is the BEST FBB168 the same as a McKinney TCA3386 heavy weight hinge?
They are the same class of part, not the same part. Both are heavy weight five knuckle square corner full mortise hinges; the McKinney TCA3386 comes at 4-1/2 x 4-1/2. Where the FBB168 differs is breadth: it spans six sizes from 4-1/2 x 4 up to 6 x 6 and ten finishes, and it can be ordered with raised barrel, hospital tips, security studs, or concealed electric wires. If you are standardizing hinge sizes and options across a building, that range is the reason to pick the FBB168.
19) What is the difference between the FBB168 and a concealed bearing hinge like the CB199?
The Stanley Security CB199 is a full mortise concealed bearing heavy weight hinge in the Architectural Hinges series, the same series as the BEST FBB168, and the Stanley Security CB1960R is a full mortise concealed bearing standard weight hinge in that series at a medium duty level. On a concealed bearing hinge the bearings are hidden within the barrel; the FBB168 uses a visible ball bearing knuckle arrangement with 5 knuckles and a removable pin. The CB199 and the FBB168 are both heavy duty, so on a heavy commercial door the choice is the barrel appearance and bearing arrangement rather than the duty rating.
20) I need a hinge on a door in a corrosive or wet area. What should I use instead of a steel hinge?
The Don-Jo BB94545 is a stainless steel full mortise ball bearing hinge, 4-1/2 by 4-1/2 with square corners, and the Don-Jo BB84545 is a brass full mortise ball bearing hinge in the same 4-1/2 by 4-1/2 size in satin chrome; both are standard duty. The BEST FBB168 is a steel hinge and is offered in 10 finishes including 600 primed for painting, 632 bright brass, 646 satin nickel and 652 satin chrome. Match the base material to the environment first, then the finish.
21) Can I mix a McKinney TCA2314 or TCA2317 with the FBB168 on the same door schedule?
The McKinney TCA2314 and TCA2317 are both square corner, 5 knuckle full mortise hinges in 4-1/2 by 4-1/2 at a standard duty level. The BEST FBB168 is a heavy duty full mortise ball bearing hinge with square corners and 5 knuckles, offered in 4-1/2 by 4-1/2 among its sizes. The corner style and mortise prep line up at that size, so they can share a frame prep, but the two McKinney models are standard duty and the FBB168 is heavy duty, which matters if the schedule calls for a single duty level across the openings.
