Don-Jo HWBB84545-626 – Frequently Asked Questions

1) Will the Don-Jo HWBB84545 hinge fit a standard commercial door prepped for a 4-1/2 inch square corner hinge?
Yes. The HWBB84545 is a 4-1/2 x 4-1/2 inch full mortise hinge with square corners, which is the standard commercial prep on hollow metal doors and frames. If your existing door and frame are cut with radius corners instead, a square corner hinge won't seat in the pocket without recutting, so match the corner style to what is already routed.
2) Do I have to order non-removable pins separately on the Don-Jo HWBB84545?
No, NRP is standard. The HWBB84545 ships with non-removable pins, so the pin can't be driven out from the hinge side when the door swings out of the secured area. That is the configuration you want on out-swinging exterior doors and out-swinging tenant or stairwell doors, and it means no NRP suffix to add on the order.
3) Is a heavy weight ball bearing hinge overkill for my building, or do I actually need one?
Heavy weight is the right call when the door is thick, tall, wide, or heavy (solid core wood, hollow metal, lead-lined, or a door carrying a closer and exit device), and when the opening cycles constantly. The HWBB84545 is a heavy duty, commercial-rated ball bearing hinge with 5 knuckles for load bearing. For light interior doors on low traffic, a medium duty ball bearing hinge such as the Orca Hardware 3535 Series in the same 4-1/2 x 4-1/2 square corner size covers it.
4) Can I use this hinge on a door that needs to self-close, or on an electrified opening?
No. The HWBB84545 is a plain butt hinge with ball bearings, no spring and no wire raceway. For a self-closing door without a surface closer, look at a spring hinge such as the Stanley Security 2060R in 4-1/2 x 4-1/2 square corner. To run power through the door for an electric lock or mag contact, use an electrified hinge like the Command Access ETH-BB68 energy transfer hinge, a 5-knuckle heavy duty unit.
5) Will this Don-Jo hinge work on a residential door with 3-1/2 inch hinges?
No. The HWBB84545 is a 4-1/2 x 4-1/2 inch hinge and will not drop into a 3-1/2 inch mortise without recutting the door and frame. For 3-1/2 inch residential openings, the Emtek 94013 heavy duty ball bearing hinge or the Deltana DSB35 square hinge come in that size as pairs.
6) What is the closest equivalent to the Don-Jo HWBB84545 heavy weight ball bearing hinge from another brand?
The Hager BB1168 is the nearest match in intent: it is a full mortise ball bearing hinge rated heavy duty with a non-removable pin, the same combination the Don-Jo HWBB84545 carries as standard. The HWBB84545 is a 4-1/2 inch by 4-1/2 inch square corner hinge with 5 knuckles in brass. If the opening is prepped for a square corner 4-1/2 by 4-1/2 mortise, the Orca Hardware 3535 Series is also a 4-1/2 by 4-1/2 square corner ball bearing commercial hinge, though Orca lists it at a medium duty level rather than heavy duty.
7) I need a 4-1/2 by 4-1/2 square corner hinge but the door has to carry wiring for an electric lock - what do I use instead?
The Don-Jo HWBB84545 is a mechanical hinge only, so it will not transfer power. For a wired opening, the Stanley Security CECB1900R54L is a three knuckle concealed bearing concealed conductor hinge in steel full mortise, 4-1/2 inch by 4-1/2 inch, square corner, left-handed, with 4 wires - the same size and corner style as the HWBB84545. If more conductors are needed, the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect, and Command Access offers the ETH-BB68 energy transfer hinge with a 5 knuckle heavy duty steel base.
8) What looks like a substitute for the HWBB84545 but will not drop into the same prep?
Several 4-1/2 inch hinges in the same family will not behave the same way. The McKinney SQ3331 is 4-1/2 inch by 4-1/2 inch but is a square barrel 2-knuckle decorative hinge at a standard duty level, not a 5-knuckle heavy weight like the Don-Jo HWBB84545. The Hager 1129 is a half mortise hinge, so it mortises into the door and surface-mounts to the frame rather than full mortise on both leaves. The Stanley 2060R at 4.5 by 4.5 square corner is a spring hinge, which self-closes the door. And the Stanley FBB191 at 4.5 by 4.5 is a 5-knuckle full mortise hinge described as standard weight, not heavy weight.
9) The frame prep on my building is 4 inch, not 4-1/2 inch - what commercial ball bearing hinge fits?
The Don-Jo HWBB84545 is sized 4-1/2 inch by 4-1/2 inch and will not fit a 4 inch mortise. For a 4 inch square corner prep, the Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners, and the Orca Hardware 4040 Series is a 4 inch by 4 inch square corner commercial hinge, though Orca uses a plain bearing at a medium duty level rather than a ball bearing. If the prep has a 1/4 inch radius corner instead, the Orca 4014 Series is the 4 inch by 4 inch radius corner version.
10) Why brass instead of steel for a commercial hinge?
The HWBB84545 uses a brass base material, which resists corrosion better than a plated steel base in damp or coastal conditions and in areas washed down regularly. It also carries a 626 Satin Chrome finish, which holds up against tarnish and matches the most common commercial lock and closer finish on the market. If you are matching existing 626 hardware across a facility, this keeps the openings consistent.
11) Does the Don-Jo HWBB84545 meet ANSI hinge standards for a commercial spec?
The HWBB84545 is ANSI A2111 compliant and built to commercial grade. That is the line item a spec writer or institutional buyer usually needs confirmed before it goes on a submittal for an office, school, healthcare or government opening.
12) Does the Don-Jo HWBB84545 need to be ordered left or right handed?
No handing to specify. A full mortise butt hinge like the HWBB84545 is symmetrical and works on either a left hand or right hand door; the pin simply installs from the top. Handing only becomes an ordering question on hinges with directional features, such as the Stanley CECB1900R54L electrified hinge, which is specified left handed.
13) The door is a light interior residential slab - is a heavy weight ball bearing hinge overkill?
For a low-traffic interior residential door, the Don-Jo HWBB84545 is built past what the opening needs; it is a heavy duty commercial hinge in brass with a ball bearing knuckle. Lighter options in the same square corner style include the Deltana DSB35 3-1/2 inch by 3-1/2 inch square hinge sold as a residential pair, the Emtek 91013 residential plain bearing hinge at 3-1/2 by 3-1/2 with square corners in plated steel, and the Schlage Residential S3P1010 3.5 by 3.5 square corner plain bearing mortise hinge in a pack of three. Those use plain bearings instead of ball bearings, so they suit lower cycle counts.
14) We want a heavy weight commercial hinge with the bearings hidden instead of visible ball bearings between the knuckles - what are the options?
The Don-Jo HWBB84545 uses a visible ball bearing knuckle stack with 5 knuckles. If the spec calls for a concealed bearing look, the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles, and the BEST CB1969R is a concealed bearing heavy weight pivot-reinforced hinge, both at a heavy duty level. For lighter openings in the same concealed style, the Ives 3CB1 is a 3-knuckle concealed bearing full mortise hinge rated medium duty.
15) Is there another 4-1/2 by 4-1/2 non-removable pin hinge if the HWBB84545 does not suit the door?
Yes. The Deltana CSB45N is a 4-1/2 inch by 4-1/2 inch square hinge sold as a pair with a non-removable pin, matching the size, corner style and NRP security of the Don-Jo HWBB84545. The Hager BB1168 is another non-removable pin full mortise ball bearing hinge at a heavy duty level. For a tamper-resistant option at a smaller size, the Deltana DE44R5TA is a 4 inch by 4 inch security hinge with a 5/8 inch radius corner in steel, which needs a radius corner prep rather than the square corner the HWBB84545 uses.
16) Is the HWBB84545 enough for a detention or correctional door?
The Don-Jo HWBB84545 is a heavy duty commercial hinge for demanding commercial openings, but detention work is a separate category. For those doors the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge in the detention hardware series, the Stanley BB855 is a double weight prison hinge furnished with no holes and not swaged at 5 inch by 6 inch, and the Hager 990 STEEL is a full surface prison hinge 3 inch by 4 inch with a welded tip at a heavy duty level.
17) I need the hinge to report door position back to the access control panel - can the HWBB84545 do that?
No. The Don-Jo HWBB84545 is a purely mechanical full mortise ball bearing hinge with no wiring or switch. For door position sensing built into the hinge, the Command Access ETM-BB68 is an energy transfer monitor hinge with an integrated door position switch at a heavy duty level, and the ETM-CB70 is the 3-knuckle steel base version with door position sensing at a medium duty level.
18) What finish does the Don-Jo HWBB84545 come in?
Satin Chrome, 626, and that is the only finish this model is built in. It is the standard commercial finish, so it lines up with 626 levers, mortise locks, exit device trim and closers already on most commercial openings.
