BEST BEST-FBB179NRP-652-4.5x4.5 – Frequently Asked Questions

1) Will the BEST FBB179NRP hinge work on an outswing exterior door where the hinges are exposed?
That's exactly what the NRP suffix is for. The FBB179NRP ships with a non-removable pin, so once the door is closed and the set screw is seated, the pin can't be driven out from the hinge side. On any outswing opening (exterior entries, stairwell doors, tenant doors that swing into a corridor) the barrels sit on the unsecured side, and a standard removable-pin hinge lets someone pull the pin and lift the door off. Use NRP hinges on every outswing leaf. On an inswing door the pin is protected already and the security feature costs you nothing.
2) Is the FBB179NRP heavy enough for a solid core door that gets constant traffic?
It's rated medium duty, for medium weight doors at average frequency. That covers most office, classroom, and tenant doors. A high traffic opening (a main entrance, a stairwell on a busy floor, a gym or cafeteria door) or a heavy leaf like a lead lined or oversized door wants a heavy weight hinge instead. From what ZenSupply carries, the Hager WTBB1168 and the McKinney TCA3386 are heavy duty ball bearing options, and the Dormakaba CB199 is a heavy weight concealed bearing hinge if you want the bearings hidden.
3) What size hinge do I order for a 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 FBB179NRP is offered in that size. The full range is 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. The first number is hinge height, the second is open width; go up in width only when you need the door to clear trim or a deeper frame return, and up in height when the leaf is heavier or taller. The 3.5 x 3.5 is for 1-3/8 inch doors, which is the older interior thickness.
4) Can I use the same hinge on both hollow metal frames and wood doors in my building?
Yes. The FBB179NRP uses template screw hole locations that suit wood and hollow metal doors and frames alike, so a property manager standardizing across a mixed building can stock one hinge instead of two. The tips and pins are reversible as well, so the same hinge handles either swing without ordering handed stock.
5) Can I use an FBB179NRP on a door with an electric lock that needs power transferred through the hinge?
No. The FBB179NRP is a mechanical hinge with a non-removable pin and no wiring provision. For power transfer to an electric strike, electrified lock or exit device on the door leaf, use an electric through-wire hinge such as the ACSI 5BB1, a 5 knuckle ball bearing full mortise hinge in 4-1/2 by 4-1/2 with concealed electric through-wire, 4 wire at 28 gauge. That size matches the 4.5 x 4.5 FBB179NRP, so a common approach is one through-wire hinge in the position nearest the lock with FBB179NRP hinges in the remaining positions - confirm the wire count against what the lock actually draws before ordering.
6) What is the closest equivalent to the BEST FBB179NRP if I need a concealed bearing instead of an exposed ball bearing?
The Stanley Security CB1960R full mortise concealed bearing standard weight hinge is the medium duty counterpart. Both sit in the Architectural Hinges series and both are rated medium duty for full mortise applications; the difference is the bearing is concealed inside the barrel on the CB1960R rather than visible between the knuckles as on the FBB179NRP. Specifiers who want an unbroken barrel line on a visible frame usually go concealed. The FBB179NRP keeps the non-removable pin, which is what matters on an out-swinging exterior or secure-side opening.
7) Will an FBB179NRP work if I need the door to swing completely clear of the opening for wheelchair access?
No - a standard full mortise hinge like the FBB179NRP holds the door leaf in the opening when it swings, so the hinge-side stile and the frame reveal eat into the clear width. For that you need a swing clear hinge such as the Hager 1260, a heavy duty full mortise swing clear hinge with a 5 knuckle plain bearing design, which throws the door out past the stop so the full frame opening is usable. Note the 1260 is plain bearing rather than ball bearing. Use the FBB179NRP where clear width is already adequate and the ball bearing is what the spec calls for.
8) The FBB179NRP is medium duty. What do I use on a heavy door or a high traffic opening?
Step up to a heavy weight hinge. The McKinney TCA3386 is a heavy duty square corner 5 knuckle full mortise hinge in 4-1/2 by 4-1/2, so it drops into the same standard mortise prep as the 4.5 x 4.5 FBB179NRP. The Stanley Security CB199 and the Dormakaba concealed bearing route also runs heavy weight, and the Hager WTBB1168 is a heavy weight 5 knuckle ball bearing hinge in 4-1/2 by 6 wide throw for openings where the door has to clear trim or swing a full 180. The FBB179NRP is built for medium weight doors with average frequency, so a heavily used entrance or a solid core fire door on a closer belongs on the heavy weight line.
9) Is a Hager 1279 a direct substitute for a BEST FBB179NRP?
Not a direct one. The Hager 1279 is a medium duty full mortise commercial hinge with 5 knuckles, so the duty rating and knuckle count line up with the FBB179NRP, but the 1279 is a plain bearing hinge. The FBB179NRP runs two permanently lubricated non-detachable ball bearings, which is what carries a door under a closer without the knuckles wearing and squeaking. If the opening was specified ball bearing, or the door has a closer on it, stay on the ball bearing hinge. The 1279 suits lower cycle interior openings with no closer.
10) I need a corrosion resistant hinge for an exterior or wet area door. What do I order instead of the steel FBB179NRP?
Go to a stainless or brass base material. The Don-Jo BB94545 is a stainless steel full mortise ball bearing hinge, 4-1/2 by 4-1/2, square corner, and the Don-Jo BB84545 is the brass version in the same 4-1/2 by 4-1/2 size and satin chrome. Both match the mortise footprint of the 4.5 x 4.5 FBB179NRP. The FBB179NRP is a steel hinge; where it is used in non-ferrous form the pins are stainless steel for corrosion resistance, but for pool rooms, coastal exteriors, kitchens and wash-down areas a stainless or brass body is the usual call.
11) Do I need to order left hand or right hand hinges?
No handing to specify. The flush tips and pins on the FBB179NRP are reversible, so one hinge works on a left hand or right hand door. You pick finish and size only. Order three hinges per leaf up to 7 feet 6 inches of door height and add one for every additional 30 inches, which is standard practice on commercial openings.
12) What is the difference between a ball bearing hinge and a plain bearing hinge, and which do I need?
Ball bearings carry the door's weight on hardened races between the knuckles, so the door swings without the knuckle-on-knuckle wear that eventually makes a plain bearing hinge squeak and sag. The FBB179NRP runs two Stanley permanently lubricated non-detachable ball bearings, meaning there's nothing to oil over the life of the hinge. Plain bearing is fine on light, low traffic doors and costs less; ZenSupply carries the Hager 1279 as a medium duty plain bearing commercial hinge and the Hager 1541 for residential. Any door with a closer on it should be ball bearing, because the closer loads the hinge every cycle.
13) What finishes does the BEST FBB179NRP come in, and which one matches painted frames?
Nine finishes: 600 primed for painting, 632 bright brass, 633 satin brass, 639 satin bronze, 640 satin bronze dark, 641 oxidized bronze, 651 bright chrome, 652 satin chrome, and 693 black. For painted hollow metal frames, order 600 primed and paint the hinge with the frame so it disappears. 652 satin chrome is the most common match for satin stainless or 630 lever trim, and 693 black suits dark storefront and modern hardware packages.
14) Can I replace a Don-Jo BB74545 or McKinney TCA2314 with the BEST FBB179NRP?
All three are 5 knuckle square corner full mortise ball bearing hinges, and the Don-Jo BB74545 and McKinney TCA2314 are both catalogued at 4-1/2 x 4-1/2, a size the FBB179NRP is offered in. Where the BEST differs is the pin: the FBB179NRP is a non-removable pin hinge, so if you're swapping in on an inswing door you gain security you didn't need, and on an outswing door you gain security you did. Match the size and the corner style to the existing prep and the screw pattern follows.
15) Will a steel hinge hold up on an exterior door or in a pool or coastal building?
The FBB179NRP is steel, which is right for interior and protected exterior commercial openings. In a wet or chlorinated environment (natatoriums, coastal exteriors, wash-down areas) steel will corrode at the knuckles and the screw heads no matter the plating, and you want stainless instead. ZenSupply carries the Don-Jo BB94545, a stainless steel 4-1/2 x 4-1/2 square corner full mortise ball bearing hinge, and the Don-Jo BB84545 in brass for the same reason.
16) What is a simpler ball bearing hinge if I do not need the non-removable pin?
The Don-Jo BB74545 is a standard duty steel full mortise ball bearing hinge, 4-1/2 by 4-1/2, square corner, 5 knuckle - the same footprint, corner style and knuckle count as the 4.5 x 4.5 FBB179NRP without the NRP feature. Don-Jo also lists the BB74540 in 4-1/2 by 4 in satin chrome, matching another size the FBB179NRP covers. The non-removable pin on the FBB179NRP exists to stop the pin being driven out from the exterior side, so on an interior office or closet door that swings in, the plain pin version is the ordinary choice; on any door where the hinge barrel is on the unsecured side, keep the NRP.
17) Is the Hager 1541 an acceptable replacement for a BEST FBB179NRP on an apartment building door?
They are aimed at different openings. The Hager 1541 is a full mortise residential hinge with stainless steel construction and a 5 knuckle plain bearing design. The FBB179NRP is a commercial hinge with ball bearings and a non-removable pin. On a multi-tenant property, unit entry doors and corridor doors that carry closers and see constant traffic are the case for the commercial ball bearing hinge; interior passage doors inside a unit are where the residential plain bearing hinge is normally used. If you are standardizing one hinge across the building's common area doors, the FBB179NRP is the one to spec.
18) How do the McKinney TCA2314 and TCA2317 compare to the BEST FBB179NRP?
Both McKinney TCA2314 and TCA2317 are standard duty square corner 5 knuckle full mortise hinges in 4-1/2 by 4-1/2, so square corner prep, knuckle count and size all match the 4.5 x 4.5 FBB179NRP and either will sit in an existing standard mortise pocket without rerouting. The TCA2314 and TCA2317 are separate models within that same size and corner configuration, so confirm which one the original schedule called out before swapping. The FBB179NRP is the choice when the opening specifically requires the non-removable pin and the two permanently lubricated ball bearings.
19) Are the ball bearings on this hinge something my maintenance crew has to grease?
Never. The two Stanley ball bearings in the FBB179NRP are permanently lubricated and non-detachable, so there's no service interval and nothing for a tech to disassemble. That's the point of specifying ball bearing on a fleet of doors: it takes hinge lubrication off the PM schedule entirely.
20) Does the FBB179NRP come with mounting screws and the set screw for the pin?
BEST supplies the FBB179NRP with the fasteners and templates for a standard install, and the manufacturer's installation guide and hinge size chart are published with the product. Use the template to lay out the screw holes on the door and frame before you cut, and set the pin's retaining screw only after the door is hung and swinging true, since an NRP set screw is meant to be seated with the door closed.
