Don-Jo PB94545-630 – Frequently Asked Questions

1) Is a plain bearing hinge like the Don-Jo PB94545 the right choice, or do I need ball bearing?
Plain bearing is for medium weight doors in low-frequency openings, which is what the PB94545 is built for: offices, storage rooms, tenant interior doors that cycle a handful of times a day. Once you add a closer, heavy traffic, or a heavier door, move to a bearing hinge. The Orca Hardware 3535 Series is the same 4-1/2 x 4-1/2 size in a square corner ball bearing, and Ives 3CB1 is a 3-knuckle concealed bearing full mortise in medium duty.
2) Will the Don-Jo PB94545 drop into my existing 4-1/2 inch hinge pockets?
It should. The PB94545 is a 4-1/2 x 4-1/2 full mortise hinge built to ANSI template, so the screw hole pattern and leaf size match standard commercial hinge prep of that size. If the door and frame were prepped for a 4-1/2 inch ANSI template hinge, no rework is needed.
3) Do I need NRP hinges on an outswing exterior door, and does Don-Jo offer that?
If the door swings out, the hinge pins are on the unsecured side and can be driven out, so NRP is the normal call on exterior and secured outswing openings. The PB94545 is available with a non-removable pin, ordered by putting NRP in front of the model number. For a reference point on the same size in another brand, Deltana's CSB45N is a 4-1/2 x 4-1/2 square hinge supplied NRP.
4) My door frame is prepped for 3-1/2 inch hinges. Can I use the Don-Jo PB94545?
No, a 4-1/2 x 4-1/2 hinge will not sit in a 3-1/2 inch pocket without recutting the door and frame. For 3-1/2 inch prep in a plain bearing hinge, look at the Orca Hardware 3514 Series with 1/4 inch radius corners or the Schlage Residential S3P1010 square corner plain bearing hinges. Check whether your existing pockets are square corner or radius before ordering.
5) I need power transfer through the hinge for an electrified lock - can the Don-Jo PB94545 do that?
The PB94545 is a mechanical full mortise plain bearing hinge with no electrical provision. For openings that carry power through the hinge, the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect at medium duty, and the Command Access ETH-CB70 is a three knuckle standard weight energy transfer hinge, also medium duty. The Command Access ETM-CB70 adds door position sensing to the transfer function. For heavy weight openings, the Command Access ETH-BB68 is a five knuckle heavy duty energy transfer hinge.
6) What is the closest equivalent to a Don-Jo PB94545 hinge in the same 4-1/2 inch by 4-1/2 inch size?
The Don-Jo PB94545 is a full mortise plain bearing hinge in a 4-1/2 inch by 4-1/2 inch size for medium weight doors. In the same size, the Orca Hardware 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner commercial hinge rated medium duty, though it uses a ball bearing rather than a plain bearing. The Deltana CSB45N is a 4-1/2 inch by 4-1/2 inch square hinge supplied as a pair with a non-removable pin. The McKinney SQ3331 is also 4-1/2 inch by 4-1/2 inch, but it is a two knuckle square barrel decorative hinge at standard duty.
7) If the door is heavier or higher traffic than the Don-Jo PB94545 is rated for, what hinge should I use instead?
The PB94545 is engineered for medium weight doors in low-frequency use. For heavier doors or busier openings, the Hager BB1168-NRP is a full mortise ball bearing hinge rated heavy duty with a non-removable pin, and the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with three knuckles. The Stanley Security FBB191 in 4-1/2 inch by 4-1/2 inch is a five knuckle full mortise standard weight hinge listed at heavy duty, and the BEST CB1969R is a concealed bearing heavy weight pivot-reinforced hinge.
8) The Don-Jo PB94545 is a full mortise hinge - what if my frame or door will not take a full mortise?
The PB94545 mortises into both the door and the frame. Where only one leaf can be mortised, the Hager 1129 is a half mortise plain bearing commercial hinge in a 4-1/2 inch standard weight steel build, and the Hager 990 STEEL is a full surface plain bearing prison hinge in 3 inch by 4 inch with a welded tip. For a door that must swing both directions, the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors rather than a hinge.
9) Is stainless steel worth it over plated steel for hinges in a coastal or wet area?
Yes, that is the reason to pick this one. The PB94545 is stainless steel with a 630 satin stainless finish, so it holds up in humid, washdown, and salt-air locations where a plated steel hinge will rust at the knuckle and around the screw heads. For dry interior work, a plated steel hinge such as the Emtek 92013 heavy duty plain bearing is the usual substitute.
10) What gauge is the Don-Jo PB94545, and is that standard or heavy weight?
The leaf gauge is 0.134, which is standard weight territory for a 4-1/2 inch commercial hinge and matches the medium weight door rating. If your door is a heavy weight slab or a lead-lined or oversized leaf, go to a heavy weight hinge instead, such as the Ives 3CB1HW concealed bearing or the Hager BB1168 NRP ball bearing.
11) How many hinges do I need per door, and how is the PB94545 packed?
Standard commercial practice is three hinges on a door up to 7 feet 6 inches tall, adding one for each additional 30 inches. The PB94545 comes in shelf packs of 24, which covers eight doors at three per leaf, so it suits a contractor or property manager doing a run of openings rather than a one-door repair.
12) Does the Don-Jo PB94545 meet a commercial hinge standard I can put on a submittal?
It is listed as ANSI A8133 compliant and ANSI template compatible, and it is a commercial grade hinge rather than a residential one. That is what a spec writer or facility procurement group will be looking for on a standard weight full mortise stainless hinge.
13) Is this hinge handed, and does the 630 finish match my other door hardware?
A full mortise plain bearing hinge like the PB94545 is non-handed, so one part number works on left and right hand doors. The finish is 630, satin stainless, which is the standard commercial finish that pairs with 630 levers, exit devices, and closers already on most office and institutional openings.
14) Can I use the PB94545 on a door that needs to self-close?
No. It is a plain bearing full mortise hinge with no spring, so it carries the door and nothing more. If you want the door to close on its own without a surface closer, a spring hinge is the part to use, such as the Stanley Security 2060R full mortise square corner spring hinge in the same 4-1/2 x 4-1/2 size.
15) Is there a plain bearing commercial hinge like the Don-Jo PB94545 in a smaller size for narrower doors?
The Don-Jo PB94545 is made in a 4-1/2 inch by 4-1/2 inch size. For smaller leaves with the same plain bearing action, the Orca Hardware 4040 Series is a 4 inch by 4 inch square corner plain bearing commercial hinge at medium duty, the Orca 4014 Series is the same 4 inch size with a 1/4 inch radius corner, and the Orca 3514 Series drops to 3-1/2 inch by 3-1/2 inch with a 1/4 inch radius corner. All three are listed medium duty plain bearing.
16) How does the Don-Jo PB94545 plain bearing differ from concealed bearing hinges of the same class?
The PB94545 uses a plain bearing, where the knuckles ride directly against each other. Concealed bearing alternatives in the medium duty class include the Ives 3CB1, a steel three knuckle concealed bearing full mortise hinge, and the Hager 920, a full mortise concealed plain bearing hinge in a two knuckle steel construction. Both hide the bearing inside the barrel instead of showing the knuckle joint, which changes the look of the exposed barrel as well as the bearing action.
17) I need the door to self-close or the hinge to resist attack - is the Don-Jo PB94545 the right choice?
The PB94545 is a standard full mortise plain bearing hinge and offers a non-removable pin option for outswing security. If the opening must close itself, the Stanley Security 2060R in 4-1/2 inch by 4-1/2 inch is a heavy duty full mortise spring hinge with square corners on a ferrous steel base. For detention-level security, the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge, and the Stanley BB855 is a double weight prison hinge in 5 inch by 6 inch furnished with no holes and not swaged. The Deltana DE44R5TA is a 4 inch security hinge with tamper-resistant pin sold in pairs.
18) Is a non-ferrous or stainless alternative available if the Don-Jo PB94545 will not suit a corrosive environment?
The PB94545 is a stainless steel hinge in a 630 finish. Where a different non-ferrous base is preferred, the McKinney T2314 is a non-ferrous five knuckle hinge in standard weight at medium duty. The McKinney MP79 and MPB79 MacPro hinges are five knuckle standard weight full mortise hinges in the same standard duty class if the application does not demand a non-ferrous base.
19) What should I use instead of the Don-Jo PB94545 on residential interior and exterior doors?
The PB94545 is a commercial hinge. For residential work, the Delaney RH35xx is a 3-1/2 inch by 3-1/2 inch bulk steel interior hinge with a 5/8 inch radius sold in pairs, and the Delaney RH45xx is the 4 inch by 4 inch exterior version with the same 5/8 inch radius. The Delaney RH40xx is a 4 inch by 4 inch residential hinge for Castlegate doors with one 5/8 inch radius corner and one square corner, and the Deltana DSB35 is a 3-1/2 inch square residential hinge in pairs.
