Stanley Security RD14FBB179 4-1/2X4-1/2 26D – Frequently Asked Questions

1) What sizes and finishes does the Stanley FBB179 ball bearing hinge come in?
The RD14FBB179 is offered in two leaf sizes, 4-1/2 x 4 inch and 4-1/2 x 4-1/2 inch, each in Black or Satin Chrome. The 4-1/2 x 4-1/2 is the usual commercial choice for a 1-3/4 inch door; the 4-1/2 x 4 is the narrower-leaf option where frame rabbet or existing mortise depth is tighter.
2) Is this Stanley hinge rated for a heavy exterior door or just interior traffic?
It's a medium duty, standard weight hinge built for medium-weight doors in average-frequency commercial traffic. For a heavy solid door, a tall door, or high-abuse traffic, step up to a heavy weight unit such as the McKinney TCA3386 4-1/2 x 4-1/2 or the Stanley CB199 concealed bearing heavy weight hinge.
3) Will this hinge work on both a wood door and a hollow metal frame?
Yes. The FBB179 is drilled to the template screw-hole pattern, so it lands correctly on both wood and hollow-metal doors and frames. That's what makes it a full mortise hinge you can standardize on across a mixed building without buying two part numbers.
4) Do I need to order a left hand and right hand version of this hinge?
No handing to specify. The tips and pins are reversible, so one hinge serves either hand. That also means a property manager can stock a single box for every door in the building.
5) What is the closest equivalent to the Stanley RD14FBB179 hinge from another brand?
The Don-Jo BB74545 is the nearest match in a steel full mortise ball bearing hinge at 4-1/2 inch by 4-1/2 inch with a square corner and 5-knuckle barrel, the same size, corner style and knuckle count as the RD14FBB179. The McKinney TCA2314 and TCA2317 are also square corner 5 knuckle full mortise hinges at 4-1/2 inch by 4-1/2 inch. All three are standard duty, while the RD14FBB179 is catalogued as medium duty, so confirm the door weight against the leaf you are replacing before you swap.
6) I need to run power through the hinge for an electric lock. Can I use the Stanley RD14FBB179?
No. The RD14FBB179 is a mechanical 5 knuckle ball bearing full mortise hinge with no wiring provision. For a power transfer opening, use the ACSI 5BB1, a 5 knuckle ball bearing full mortise hinge at 4-1/2 inch by 4-1/2 inch with a concealed electric through-wire, 4 wire 28 gauge. It is the same size and mortise footprint, so it can take the place of one leaf in a set while the remaining hinges stay conventional.
7) Which hinge should I use if the door is too heavy for a standard weight ball bearing hinge?
Step up to a heavy weight hinge. The McKinney TCA3386 is a heavy weight square corner 5 knuckle full mortise hinge in the same 4-1/2 inch by 4-1/2 inch size, so the mortise prep carries over. The Stanley Security CB199 is a full mortise concealed bearing heavy weight hinge in the same Architectural Hinges series as the RD14FBB179, and the BEST CB223 is a heavy weight concealed bearing pivot reinforced hinge in stainless steel for beveled edge doors. The RD14FBB179 itself is a medium duty hinge.
8) Is a plain bearing hinge like the Hager 1279 the same thing as the Stanley RD14FBB179?
No. The Hager 1279 is a full mortise plain bearing commercial hinge with 5 knuckles and a medium duty rating, so it matches the RD14FBB179 on knuckle count, mortise type and duty class, but it uses a plain bearing rather than the ball bearing construction of the RD14FBB179, which carries two permanently lubricated non-detachable ball bearings. The Hager 1260 is also plain bearing, and the Hager 1541 is a plain bearing stainless hinge described as residential. If the opening is a frequently cycled commercial door specified for ball bearing hinges, the plain bearing models are not a direct substitution.
9) Can the pin be taken out to lift the door off without unscrewing the hinge?
Yes, the pin is removable, and there's a hole in the bottom leaf tip so you can drive it out from below. Handy for pulling a door for painting or for getting large equipment through an opening. The ball bearings themselves are non-detachable and permanently lubricated, so they stay in place and need no greasing.
10) Ball bearing or plain bearing hinge for a door with a closer on it?
Use ball bearing. The FBB179 carries two permanently lubricated ball bearings, which is what you want on any door under a closer or in frequent use, because the closer's force is what wears a plain bearing knuckle and starts the sag. Plain bearing options like the Hager 1279 are for low-frequency interior openings with no closer.
11) Does this Stanley hinge meet ANSI/BHMA standards for ball bearing hinges?
It is stated as compliant with ANSI/BHMA A156.1, the standard covering butt hinges including ball bearing types. Useful if you are writing it into a hardware schedule for an institutional opening.
12) What is the difference between the Stanley RD14FBB179 and the BEST 1900R?
Both are steel full mortise standard weight hinges with removable pins in the Architectural Hinges series and both are medium duty. The RD14FBB179 is described as a five knuckle ball bearing hinge with reversible flush tips and a pin removal hole in the bottom leaf tip, offered in 4-1/2 inch by 4 inch and 4-1/2 inch by 4-1/2 inch sizes in Black and Satin Chrome. The BEST 1900R is a concealed bearing design. Concealed bearing barrels present a smooth uninterrupted knuckle line, while the RD14FBB179 is also catalogued with a concealed bearing type, so the two are close functional peers on most standard commercial openings.
13) Is there a stainless steel or brass version if the Stanley RD14FBB179 will corrode in a wet or coastal location?
The RD14FBB179 is a steel hinge. For a different base material in the same 4-1/2 inch by 4-1/2 inch full mortise ball bearing format, the Don-Jo BB94545 is stainless steel with a square corner, and the Don-Jo BB84545 is brass in satin chrome. Both are standard duty. The BEST CB223 is a stainless steel concealed bearing hinge as well, though it is heavy weight and prepped for beveled edge doors.
14) What do I order if the door has to clear a deep trim or swing past an obstruction?
That calls for a wide throw hinge rather than the 4-1/2 inch by 4-1/2 inch RD14FBB179. The Hager WTBB1168 is a 4-1/2 inch by 6 inch full mortise ball bearing wide throw hinge, heavy weight, with 5 knuckles. The extra leaf width pushes the door further off the frame at full swing. Frame prep differs from a 4-1/2 inch square hinge, so verify the existing mortise before substituting.
15) I need a 4-1/2 by 4 inch hinge rather than a square 4-1/2. What are my options?
The RD14FBB179 is offered in a 4-1/2 inch by 4 inch size as well as 4-1/2 inch by 4-1/2 inch, in Black and Satin Chrome. If you want a cross-brand match in that narrower leaf, the Don-Jo BB74540 is a full mortise ball bearing hinge at 4-1/2 inch by 4 inch in satin chrome, standard duty.
16) Are the bearings visible on the knuckle, or hidden?
Concealed. The bearings sit inside the 5-knuckle barrel rather than showing as separate raceways between knuckles, so the hinge reads as a clean barrel on finished openings in Satin Chrome or Black.
17) Is the BEST FBB212 a drop-in replacement for the Stanley RD14FBB179?
Not on a typical opening. The FBB212 is a steel ball bearing pivot reinforced hinge for square edge doors in a heavy weight configuration, standard duty rated, and pivot reinforced hinges are intended for doors carrying a reinforcing pivot arrangement. The RD14FBB179 is a conventional medium duty full mortise butt hinge with reversible flush tips and a removable pin. Use the FBB212 only where the door and frame are prepped for a pivot reinforced hinge.
