BEST FBB179-626-4.5x4.5 – Frequently Asked Questions

1) Will the BEST FBB179 hinge work on a hollow metal frame, or is it only for wood doors?
Both. The FBB179 is drilled to template screw hole locations, so the same hinge goes on wood or hollow metal doors and frames without a separate part number. It's a full mortise hinge, meaning both leaves mortise into the door edge and the frame rabbet, so the opening has to be prepped for it either way.
2) What size hinge do I order for a standard 1-3/4 inch commercial door?
For a standard 1-3/4 inch commercial door the usual call is 4-1/2 x 4-1/2, and the FBB179 offers it. Eight sizes are made: 3 x 4.5, 3.5 x 3.5, 4 x 4, 4.5 x 4, 4.5 x 4.5, 4.5 x 5, 5 x 4 and 5 x 5 inches. The first number is leaf height, the second is open width, so a wider second number is what you use when the door has heavy trim or a deep reveal and needs to clear it.
3) Is the FBB179 heavy enough for a busy entrance door?
No. The FBB179 is rated medium duty, for medium weight doors of average frequency use. A high-traffic entrance, a heavy metal door, or an opening that cycles all day wants a heavy weight hinge instead, such as the McKinney TCA3386 or the Hager WTBB1168, both heavy duty. Put the FBB179 on offices, classrooms, patient rooms, and unit doors, not on the front door of the building.
4) Do I need to order the FBB179 by hand, left or right?
No handing to specify. Flush tips and pins on the FBB179 are reversible, so one hinge covers either swing. Pick finish and size and you're done.
5) Can I take a door down without unscrewing the hinges?
Yes. The FBB179 uses a removable pin with a hole in the bottom tip, so you drive the pin up and out and lift the door off, leaving both leaves screwed in place. That's what you want for painting, moving furniture, or swapping a door leaf. It also means the pin can be pulled from the hinge side, so on an out-swinging exterior or secure opening you'd want a non-removable or security pin hinge instead.
6) Ball bearing or plain bearing hinge for a commercial door?
Ball bearing, on anything that gets real use or carries a closer. The FBB179 runs two permanently lubricated, non-detachable ball bearings that take the vertical load off the knuckles and cut friction, which is why they hold up under a closer. Plain bearing hinges like the Hager 1279 (also medium duty) or the residential Hager 1541 cost less to buy and are fine on light interior doors with no closer and low cycle counts. If the door has a closer on it, go ball bearing.
7) Will a square corner hinge drop into my existing hinge pockets?
Only if the existing pockets are square cut. The FBB179 has square corners, which is standard on hollow metal frames and most commercial prep. Older wood doors are often routed with radius corners (usually 1/4 or 5/8 inch radius), and a square corner hinge will not sit flush in those without chiseling the corners out. Check one existing pocket before you order the set.
8) What is the closest equivalent to a BEST FBB179 hinge from another manufacturer?
The Stanley Security CB1960R full mortise standard weight hinge is the nearest match on duty class, since both the FBB179 and the CB1960R are medium duty full mortise hinges in the Architectural Hinges series. The difference is the bearing arrangement: the FBB179 uses ball bearings, while the CB1960R is a concealed bearing hinge, so the bearing is hidden within the knuckle rather than visible between knuckles. If the specification or the existing openings call for a visible ball bearing knuckle, stay with the FBB179; if the architect wants the smooth knuckle appearance, the CB1960R covers the same duty class.
9) I need to run power through the door for an electric lock. Can the FBB179 carry the wire?
The FBB179 is a mechanical hinge with a removable pin and no wire path through it. To transfer power from the frame to the door at the hinge, the ACSI 5BB1 is a 5 knuckle ball bearing full mortise hinge in 4-1/2 by 4-1/2 with concealed electric through-wire, 4 wire in 28 gauge, from the 1100 Series. Integrators typically install one electric through-wire hinge in the hinge stack and fill the remaining positions with standard hinges such as the FBB179, so match the size and finish across the opening when you order.
10) The door has to clear deep trim or a thick wall condition. Is there a wider hinge than the FBB179 sizes?
The FBB179 tops out at a 5 inch by 5 inch size, where the second dimension is the open width of the two leaves. When a door has to swing past deep casing, a projecting frame, or a thick wall return, the part to look at is a wide throw hinge: the Hager WTBB1168 is a 4-1/2 inch by 6 inch full mortise ball bearing wide throw hinge with 5 knuckles. The 6 inch open width pushes the door further off the frame than any FBB179 size will. It is also a heavy weight hinge, where the FBB179 is medium duty, so verify the frame prep will take the larger leaf.
11) What hinge should I use instead of the FBB179 on a heavy door or a high traffic entrance?
The FBB179 is built as a medium duty hinge for medium weight doors of average frequency use, so a heavy or high cycle opening should move up a class. The McKinney TCA3386 is a heavy weight square corner 5 knuckle full mortise hinge in 4-1/2 by 4-1/2, which keeps the same square corner and 5 knuckle format the FBB179 uses. The Stanley Security CB199 is a heavy duty full mortise concealed bearing hinge in the same Architectural Hinges series. Both carry a heavy duty rating where the FBB179 is medium duty.
12) Is a plain bearing hinge like the Hager 1279 the same thing as the BEST FBB179?
They are not the same. Both are medium duty full mortise commercial hinges with 5 knuckles, but the Hager 1279 is a plain bearing hinge while the FBB179 carries two permanently lubricated non-detachable ball bearings. A plain bearing hinge runs metal on metal at the knuckle; the ball bearing construction in the FBB179 reduces friction and wear, which is why ball bearing is what most commercial door specifications call out. If a drawing specifies a ball bearing hinge, the 1279 will not satisfy it even though the duty class matches.
13) What finishes does the BEST FBB179 hinge come in to match the rest of my door hardware?
Eleven, spanning the common architectural numbers: 600 primed for painting, 632 bright brass, 633 satin brass, 638 satin brass blackened, 639 satin bronze, 640 satin bronze dark, 641 oxidized bronze, 646 satin nickel, 651 bright chrome, 652 satin chrome, and 693 black. If you're matching existing openings, read the finish number off the lockset or the old hinge rather than eyeballing the color, since 632 and 651 look close from across a corridor. The 600 primed option is the one to take when the hinges get painted with the frame.
14) I need a hinge that swings the door clear of the opening for wheelchair access. Is this it?
No. The FBB179 is a conventional full mortise hinge and the door leaf stays in the opening when it's open, taking up part of the clear width. For a door that swings fully clear of the frame to recover that width, the Hager 1260 is a full mortise swing clear hinge, 5 knuckle plain bearing, heavy duty. That's the hinge type used to gain clear opening width on an existing frame without widening the rough opening.
15) What is the difference between the BEST FBB179 and the Don-Jo BB74545 or McKinney TCA2314?
All three are square corner 5 knuckle full mortise ball bearing hinges, and the Don-Jo BB74545 and McKinney TCA2314 are both 4-1/2 by 4-1/2, a size the FBB179 also offers. The BB74545 is steel with a square corner and the TCA2314 is square corner 5 knuckle full mortise; both are rated standard duty, while the FBB179 is rated medium duty. The FBB179 is the one to order when you need to hold a single hinge model across a range of leaf sizes from 3 inch by 4.5 inch up to 5 inch by 5 inch and across eleven finishes; the single size peers are the straight one-for-one swap when a 4-1/2 by 4-1/2 door needs a hinge and nothing else on the job has to match.
16) I need a ball bearing hinge in 4-1/2 x 4-1/2 square corner but not in steel. What are my options?
The FBB179 is a steel hinge, so for other base materials in the same 4-1/2 by 4-1/2 square corner full mortise ball bearing format, look at the Don-Jo BB84545, which is brass in satin chrome, or the Don-Jo BB94545, which is stainless steel with a square corner. Both are standard duty. Stainless is the usual choice for exterior openings, coastal sites, and wash-down areas such as kitchens and healthcare. Note the FBB179 does offer 4.5 inch by 4.5 inch as a size and includes plated finishes such as 632 Bright Brass and 652 Satin Chrome over steel, which is a different thing from a solid brass or stainless hinge.
17) I need a 4-1/2 x 4 hinge in satin chrome. What are the choices?
The FBB179 offers a 4.5 inch by 4 inch size and a 652 Satin Chrome finish over steel, so that combination is available as one part. The Don-Jo BB74540 is a full mortise ball bearing hinge in 4-1/2 by 4 in satin chrome as a single standard duty part. The FBB179 is medium duty against the BB74540 standard duty rating, and the FBB179 also gives you 651 Bright Chrome if the existing hardware on the opening is polished rather than satin.
18) Can I use the FBB179 on apartment interior doors, or is there a lighter residential hinge?
The FBB179 is a commercial hinge, and property managers do specify it on unit entry doors precisely because the ball bearing construction holds up to the traffic. For lighter interior doors inside a unit, the Hager 1541 is a full mortise residential hinge with stainless steel construction and a 5 knuckle plain bearing design. The split most fleets settle on is the ball bearing FBB179 on corridor and unit entry doors, where the door is heavier and cycles constantly, and a plain bearing residential hinge on bedroom and closet doors behind them.

    The ball bearing makes the swing incredibly smooth and quiet. Installation was standard, and the steel feels very durable.
