Stanley Security FBB191 4.5 X 4.5 US26D/652 – Frequently Asked Questions

1) Will a Stanley 4-1/2 x 4-1/2 full mortise hinge work on both a hollow metal frame and a wood door?
Yes. The Stanley FBB191 full mortise hinge is drilled to template screw hole location, so it works on either wood or hollow metal doors and frames, and it ships packed with both wood and machine screws. For a 4-1/2 x 4-1/2 hinge that means 8-12-24 x 1/2 machine screws and 8-12 x 1-1/4 wood screws in the box, so you are not chasing fasteners on the jobsite.
2) Is this Stanley ball bearing hinge heavy enough for a commercial entry door that gets constant traffic?
It is built for medium weight doors of average frequency, with two permanently lubricated non-detachable ball bearings. Steel construction, commercial rated, square corners. On an opening that cycles all day (a main entry, a stairwell, a heavily used corridor door) step up to a heavy weight hinge instead, such as the Don-Jo HWBB74545 in the same 4-1/2 x 4-1/2 size or the Ives 3CB1HW heavy weight concealed bearing hinge.
3) What gauge is a Stanley 4-1/2 inch x 4-1/2 inch hinge, and will it drop into my existing 4-1/2 mortise?
The 4-1/2 x 4-1/2 (114mm x 114mm) size runs .134 inch (3.4 mm) gauge with square corners. If the frame and door are already cut for a square corner 4-1/2 x 4-1/2 hinge, it goes back in the same pocket. If your existing mortise has rounded corners, it will not seat cleanly without recutting; go to a radius corner hinge instead.
4) Can I get a Stanley 5-knuckle mortise hinge with non-removable pins for an out-swinging exterior door?
Yes. The hinge can be furnished with non-removable pins (NRP), and that is the option to specify on any out-swing door where the barrel is on the outside, since an ordinary pin can be driven out and the door lifted. Security studs are also available as an option on the same hinge. If you would rather order an NRP hinge as a stock item, the Hager BB1168 is offered as a non-removable pin full mortise ball bearing hinge, and the Deltana CSB45N is a 4-1/2 x 4-1/2 square hinge pair with NRP.
5) I need to run power through the door for an electric lock. Can this Stanley hinge carry the wires?
It can be furnished with electric wires and/or switches (the CE and CS options), which lets you transfer power to an electrified lock or exit device without a separate power transfer. If you want a purpose-built electrified hinge instead, the Command Access ETH-BB68 is a 5-knuckle heavy duty steel energy transfer hinge, the BEST CECB179-12C is a full mortise concealed bearing electrified hinge with a 12-wire quick connect, and the Command Access ETM-BB68 adds an integrated door position switch if you also need to monitor whether the door is closed.
6) What is the closest equivalent to the Stanley FBB191 4-1/2 x 4-1/2 ball bearing hinge from another brand?
The Don-Jo HWBB74545 is a full mortise ball bearing hinge in the same 4-1/2 inch by 4-1/2 inch size, offered in satin chrome, which matches the 652 satin chrome finish the FBB191 is furnished in. Don-Jo also builds the HWBB84545 in the same 4-1/2 by 4-1/2 size and satin chrome. Both are full mortise ball bearing hinges like the FBB191, so the door and frame mortise prep does not change when you swap.
7) I need a 5 inch by 4-1/2 inch ball bearing hinge instead of 4-1/2 by 4-1/2 for a thicker door. What should I order?
The Don-Jo HWBB75045 is a heavy weight full mortise ball bearing hinge in 5 inch by 4-1/2 inch steel with a satin chrome finish. Don-Jo also lists the HWBB85045 in the same 5 by 4-1/2 size in brass with a satin chrome finish, which is the choice when a non-ferrous body is wanted. Both keep the full mortise ball bearing arrangement while giving you the wider leaf a thicker or heavier door needs.
8) Is there a square corner ball bearing commercial hinge in 4-1/2 x 4-1/2 besides the Stanley FBB191?
The Orca Hardware COM3535 is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge in the 3535 series, rated medium duty. It shares the square corner and ball bearing construction of the FBB191, which also has square corners. If your existing mortise is radius cornered instead, Orca builds the COM4014 as a 4 inch by 4 inch with a 1/4 inch radius corner.
9) I need a non-removable pin hinge for an outswing exterior door. What are my options?
The Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge, which keeps the ball bearing construction while defeating pin pulling from the outside. The Deltana CSB45N is a 4-1/2 inch by 4-1/2 inch square hinge sold in pairs with a non-removable pin. Stanley can also furnish the FBB191 with non-removable pins under the NRP option, so you can hold the same hinge on the outswing openings as the rest of the building.
10) What do I use if the frame is prepped for a half mortise hinge rather than a full mortise?
The Hager 1129 is a half mortise plain bearing commercial hinge, 4-1/2 inch standard weight steel. A half mortise hinge mortises into the door but surface applies to the frame, so it is not interchangeable with the FBB191, which is a full mortise hinge mortised into both the door and the frame. Check which prep is in the opening before ordering either one.
11) The door needs to swing both directions. Can I use a full mortise butt hinge?
No, a full mortise butt hinge such as the FBB191 swings one direction only. For a door that swings both ways, the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors. It is a pivot rather than a butt hinge, so the door and frame prep is entirely different from a hinge mortise.
12) For a heavy door with a closer, is there a hinge built for more load than a standard weight ball bearing hinge?
The BEST CB1969R is a concealed bearing heavy weight pivot-reinforced hinge rated heavy duty, built for openings carrying more load than a standard weight hinge handles. The Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles, also heavy duty. The FBB191 is described for medium weight doors of average frequency, so on a heavy door with a closer and constant traffic the heavy weight body is the better match.
13) What finishes does the Stanley FBB191 hinge come in?
Two: 652 satin chrome over steel, and 630 satin stainless steel. 630 is the one to pick for exterior openings, wet or coastal locations, and anywhere the rest of the door hardware is already 630. If you are matching existing satin chrome levers and closers in the building, 652 keeps the opening consistent.
14) Do I have to order a left hand and right hand version of this hinge?
No handing to specify. The hinge has reversible flush tips and pins, so the same part works on a left or right hand door. There is also a hole in the bottom tip so you can drive the pin out from underneath, which matters when you are pulling a door in a corridor with no room to work above the top hinge.
15) What is the difference between a ball bearing hinge and a plain bearing hinge, and which do I need?
Ball bearing hinges carry a bearing race between the knuckles so the door swings under load without the knuckles wearing into each other. This Stanley hinge uses two permanently lubricated non-detachable ball bearings, which is what you want on a door with a closer on it, a fire door, or anything heavy. Plain bearing is metal on metal and is fine on light interior doors with no closer, such as the Orca 4040 series 4 x 4 square corner plain bearing hinge or the Hager 920 concealed plain bearing hinge. If the door has a closer, do not use plain bearing.
16) What is a 5-knuckle full mortise hinge, and does it need to be cut into both the door and the frame?
Full mortise means both leaves get mortised in, one into the door edge and one into the frame rebate, so the hinge sits flush and nothing shows but the barrel. The Stanley hinge has 5 knuckles, the standard commercial arrangement, three on one leaf and two on the other. If your frame cannot be mortised, that is a different hinge entirely: a half mortise like the Hager 1129 mortises into the door and screws to the face of the frame, and a full surface hinge screws to both faces.
17) I need hospital tips on the hinges for a healthcare corridor. Can I get them on this Stanley hinge?
Yes, hospital tips (HT) are one of the available options. Hospital tips slope the barrel ends so IV lines, gowns, and cart straps cannot catch, which is why healthcare facilities specify them on patient room and corridor doors. Raised barrel (RB) and decorative tips can also be furnished on the same hinge if the opening calls for them.
18) What size Stanley hinge do I need for a 4-1/2 inch wide door edge versus a 5 inch door?
Hinge leaf height is picked off door weight and width, and gauge goes up with size: a 4 x 4 runs .130 (3.3 mm), a 4-1/2 x 4-1/2 runs .134 (3.4 mm), a 5 x 4-1/2 runs .146 (3.7 mm), and a 6 x 4-1/2 runs .160 (4.1 mm). If you are matching what is already hung, measure the existing hinge leaf and order the same size, because a different leaf height will not line up with the cut mortise. Standard commercial practice is 4-1/2 inch hinges on a 1-3/4 inch door.
19) What is the difference between a 5-knuckle ball bearing hinge and a concealed bearing hinge like the Ives 3CB1?
The FBB191 is a 5-knuckle full mortise hinge with two permanently lubricated non-detachable ball bearings visible between the knuckles. The Ives 3CB1 is a 3-knuckle concealed bearing full mortise hinge rated medium duty, where the bearing sits inside the barrel and the knuckle line reads as a plain barrel. The Ives 3CB1HW is the heavy weight version of that concealed bearing 3-knuckle design. All three mortise into the door and frame the same way; the knuckle count and whether the bearing shows are what change.
20) What should I use on a detention or prison door instead of a standard mortise ball bearing hinge?
Detention openings take a purpose-built hinge. The BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge in the detention hardware line. The Hager 990 STEEL is a full surface prison hinge, 3 inch by 4 inch, with a welded tip and a heavy duty plain bearing. Note the Hager 990 is full surface rather than full mortise like the FBB191, so it mounts to the face of the door and frame rather than into a mortise.
21) Is a McKinney MP79 a substitute for a Stanley 5-knuckle standard weight full mortise hinge?
The McKinney MP79 MacPro is a full mortise hinge with 5 knuckles in standard weight, the same knuckle count and full mortise mounting as the FBB191. McKinney also lists the MPB79 MacPro as a 5-knuckle standard weight hinge. Where they part from the FBB191 is bearing type: the Stanley carries two permanently lubricated non-detachable ball bearings, so confirm the bearing arrangement your spec calls for before swapping.
22) I need a hinge that also tells the access control panel whether the door is closed. What is different from a plain hinge?
An energy transfer monitor hinge adds door position sensing to the power transfer. The Command Access ETM-BB68 is an energy transfer monitor hinge with an integrated door position switch, rated heavy duty in the ETM 5 series. The ETM-CB70 is the 3-knuckle standard weight steel base version with door position sensing, rated medium duty. A standard ball bearing hinge like the FBB191 carries the door only; Stanley does offer the CS switch option if you want the switch in the Stanley body.
23) I want a stainless or non-ferrous hinge for a coastal or wash-down opening. What are the choices?
The FBB191 is offered in a 630 satin stainless steel finish, and its non-ferrous versions use stainless steel pins. From another maker, the McKinney T2314 is a non-ferrous hinge in standard weight with 5 knuckles, the same knuckle count. The Don-Jo HWBB85045 is a 5 inch by 4-1/2 inch brass hinge with a satin chrome finish if a brass body suits the opening better than stainless.
24) Do I need a special hinge for a patient room door in a healthcare facility?
Hospital tip hinges are the usual call there, since the sloped tip leaves nothing for a cord or strap to catch on. Stanley furnishes the FBB191 with hospital tips under the HT option, on the same 5-knuckle ball bearing full mortise body used elsewhere in the facility, so the door and frame prep stays consistent across the building.
25) Is this Stanley hinge suitable for residential interior doors, or is it overkill?
It is a commercial hinge in steel, and on a lightweight interior bedroom or closet door it is more hinge than the opening needs. For residential work, the Delaney 3-1/2 x 3-1/2 bulk interior residential hinges come as a pair with a 5/8 inch radius, the Schlage Residential S3P1010 is a 3-1/2 x 3-1/2 square corner plain bearing mortise hinge in a pack of three, and the Emtek 91013 is a 3-1/2 x 3-1/2 square corner residential plain bearing pair. Where the residential door is exterior and heavier, the Delaney 4 x 4 exterior residential hinge is the closer match.
26) Are the pins on the stainless steel version of this hinge stainless too?
Pins in the non-ferrous hinges are stainless steel, so the pin will not be the part that rusts out on an exterior or damp opening. That is the reason to take the 630 satin stainless finish rather than the 652 satin chrome over steel where the door sees weather.
27) Is a decorative square barrel hinge the same thing as a 5-knuckle ball bearing hinge in 4-1/2 x 4-1/2?
They share a size but not a construction. The McKinney SQ3331 is a square barrel 2-knuckle decorative hinge, 4-1/2 inch by 4-1/2 inch, rated standard duty. The FBB191 in the same 4-1/2 by 4-1/2 size is a 5-knuckle ball bearing hinge. The 2-knuckle square barrel is chosen for how the barrel looks on the opening; the 5-knuckle ball bearing body is chosen for commercial service.
