BEST BEST-F191NRP-626-3.5x3.5 – Frequently Asked Questions

1) Will the BEST F191NRP hinge stop someone pulling the pin from the outside?
That is the whole point of the NRP suffix. The F191NRP uses a non-removable pin, so once the door is hung the pin cannot be driven out from the hinge knuckle. That matters on any out-swinging door where the hinge barrel sits on the unsecured side, exterior entries, stairwell doors, tenant doors, mechanical and IT rooms. On an in-swinging door the barrel is already protected and a standard removable pin hinge does the same job.
2) Is a plain bearing hinge good enough for a high traffic commercial door?
Plain bearing is the wrong choice for high traffic. The F191NRP is a medium duty, plain bearing hinge, which suits office interiors, closets, and low-cycle rooms. Once you add a closer or the door sees constant use, go ball bearing or concealed bearing so the load rides on bearings instead of knuckle on knuckle. In the same architectural line, the Stanley Security CB1960R is a concealed bearing standard weight hinge, and the CB199 is the concealed bearing heavy weight version for the heaviest doors.
3) Will a square corner hinge drop into my existing door and frame mortise?
Only if the existing mortise is square cornered. The F191NRP has square corners, which is the standard prep on hollow metal doors and frames and on machine-routed commercial wood doors. If the pocket in your door has rounded corners, a 1/4 or 5/8 inch radius from a hand router or a residential template, a square corner leaf will not seat without chiseling the corners out. Pull one existing hinge and look at the pocket before you order.
4) What is the closest alternative to the BEST F191NRP if I want ball bearing instead?
Staying at 4-1/2 x 4-1/2 with a square corner, 5 knuckle body, the Don-Jo BB74545 is the steel standard duty ball bearing version, the BB94545 is the same in stainless steel, and the BB84545 is brass in satin chrome. The McKinney TCA2314 and TCA2317 are also 4-1/2 x 4-1/2 square corner 5 knuckle standard duty hinges. Note that none of those carry the non-removable pin, so if the door swings out and the barrel is exposed, the F191NRP is the one that solves that.
5) Can I use the BEST F191NRP for a door with an electric strike or electrified lock that needs power transferred through the hinge?
No. The F191NRP is a plain bearing full mortise hinge with no provision for wiring. For power transfer through the hinge, the ACSI 5BB1 is a 5 knuckle ball bearing full mortise hinge in 4-1/2 by 4-1/2 with a concealed electric through-wire, 4 wire 28 gauge. Common practice is one electrified hinge per opening with the remaining hinges standard, so the F191NRP can still fill the other positions at the matching 4-1/2 by 4-1/2 size.
6) I need the door leaf to clear the opening for a wheelchair. Will the BEST F191NRP work?
No, a standard full mortise hinge keeps the door within the opening when open. For clear width you need a swing clear hinge: the Hager 1260 is a full mortise swing clear hinge with a 5 knuckle plain bearing design, heavy duty. It shares the plain bearing function and 5 knuckle build of the BEST F191NRP, but the leaf geometry swings the door out of the opening. Use the F191NRP on the doors where clear width is not the issue and the 1260 on the ones that need it.
7) What is the closest equivalent to the BEST F191NRP if I need a full mortise plain bearing hinge from another manufacturer?
The Hager 1279 is the closest match. Like the BEST F191NRP, it is a full mortise hinge with a plain bearing function, 5 knuckles, and a medium duty rating. Both are built for commercial openings. The difference to confirm before you order is the pin: the F191NRP is supplied with a non-removable pin for tamper resistance, so if the opening is an out-swinging exterior or corridor door where pin security drove the spec, stay with the F191NRP.
8) The door is high traffic and the plain bearing hinge keeps wearing out. What should I use instead?
Move to a bearing hinge rated for the traffic. The McKinney TCA3386 is a heavy duty square corner 5 knuckle full mortise hinge in 4-1/2 by 4-1/2, which matches the 4-1/2 by 4-1/2 size and square corners the BEST F191NRP is offered in, so the existing mortise prep carries over. The Stanley Security CB199 is another heavy duty full mortise option, with a concealed bearing. The F191NRP is a medium duty plain bearing hinge, which suits offices and interior rooms rather than an entrance cycling all day.
9) Is a ball bearing hinge like the Don-Jo BB74545 a drop-in replacement for a plain bearing hinge?
Dimensionally it can be. The Don-Jo BB74545 is a full mortise ball bearing hinge in 4-1/2 by 4-1/2 steel with square corners and 5 knuckles, so it lines up with the 4-1/2 by 4-1/2 square corner size the BEST F191NRP is sold in. What changes is the pin and the bearing. The BB74545 is a standard duty ball bearing hinge; the F191NRP is medium duty with a plain bearing and a non-removable pin. If the reason the F191NRP was specified was pin security on an out-swinging door, a ball bearing hinge with a removable pin does not replace it. Don-Jo also lists the BB84545 in brass and the BB94545 in stainless steel at the same 4-1/2 by 4-1/2 size if the material needs to match brass or stainless trim.
10) My existing hinge is 4-1/2 by 4 inches, not square. Does the BEST F191NRP fit that prep?
No. The F191NRP is offered in square sizes of 3-1/2 by 3-1/2, 4 by 4, and 4-1/2 by 4-1/2. For a 4-1/2 by 4 inch leaf, the Don-Jo BB74540 is a full mortise ball bearing hinge at 4-1/2 by 4 in satin chrome, standard duty, which matches that frame rabbet and door leaf combination directly.
11) Can I use the BEST F191NRP on both wood doors and hollow metal frames?
Yes, on both. It is a full mortise hinge with template screw hole locations, so the hole pattern lands where a standard commercial template puts it and it works on wood or hollow metal doors and frames. Full mortise means both leaves get let into the surface, one into the door edge and one into the frame rabbet, so it needs a prepped opening rather than a surface mount.
12) Do I need to specify handing when ordering the F191NRP hinge?
No. A full mortise butt hinge with square corners is symmetrical and works on a left or right hand door either way up, so there is no hand to specify. Order by size and finish only. Handing only becomes a factor on swing clear or wide throw hinges, not on a standard butt like this one.
13) Which finish should I pick to match the rest of the doors in my building?
Eight finishes are offered across all three sizes: 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. These are BHMA finish numbers, so match the number stamped or specified on your existing hardware rather than the words. 626 is the most common commercial interior finish and 630 the usual choice for exterior or wet locations because of the stainless base.
14) My door has thick trim or casing and binds on the frame when it opens. Will a standard hinge fix it?
Not this one. The F191NRP is a standard throw hinge, so the door pivots close to the frame and will keep hitting the trim. What you need is a wide throw hinge, which uses a longer leaf to push the pivot point further out. The Hager WTBB1168 is a 4-1/2 x 6 inch full mortise ball bearing wide throw hinge, heavy weight, 5 knuckles, the extra leaf width is where the clearance comes from.
15) Can I standardize on the F191NRP across an entire facility?
Across the interior and low-traffic openings, yes, and that is where it fits, it is a commercial grade hinge in three sizes and eight BHMA finishes so one part number covers most doors in a building. The limit is duty: it is medium duty plain bearing, so exit doors, closered doors, and high-cycle corridor doors should step up to a bearing hinge such as the Stanley Security CB1960R concealed bearing standard weight, or the heavy weight CB199 on the heaviest leaves. Both are in the same Architectural Hinges line, so the finishes and prep stay consistent.
16) For an apartment interior door, do I need the BEST F191NRP or is there a lighter option?
The Hager 1541 is a full mortise plain bearing residential hinge in stainless steel with a 5 knuckle design, which covers interior residential doors. The BEST F191NRP is a commercial medium duty hinge with a non-removable pin, which is what you want on unit entry doors and corridor doors where pin security and traffic matter. Many property managers run the 1541 inside the unit and the F191NRP at the entry.
17) What is the difference between the BEST F191NRP and the Stanley Security CB1960R?
Both are full mortise standard weight hinges rated medium duty and both sit in the Architectural Hinges series. The bearing differs: the CB1960R is a concealed bearing hinge, where the bearing is hidden inside the barrel, while the F191NRP uses a plain bearing and carries a non-removable pin. Choose on whether the job calls for a concealed bearing appearance or for a fixed pin on the door.
18) How do the McKinney TCA2314 and TCA2317 compare to the BEST F191NRP?
Both McKinney models are square corner 5 knuckle full mortise hinges at 4-1/2 by 4-1/2, standard duty, so they share the corner style, knuckle count, and one of the sizes the BEST F191NRP is sold in. The F191NRP is medium duty and comes with a non-removable pin. If you are standardizing a facility on one hinge and pin security is part of the spec, the F191NRP is the one that carries it.
