McKinney MP79 4-1/2X4-1/2 26D – Frequently Asked Questions

1) Is the McKinney MP79 hinge approved for a fire-rated door opening?
The MP79 is not the model McKinney lists for fire-rated openings. McKinney names the MPB79 and MPB68 as approved for NFPA 80 fire-rated openings. If the opening is fire-rated, specify one of those two.
2) What sizes and finishes does the McKinney MP79 MacPro hinge come in?
Two sizes, 4-1/2 x 4 inches and 4-1/2 x 4-1/2 inches, each in 626 satin chrome or 600 primed for painting, and each with or without a non-removable pin. The 4-1/2 x 4-1/2 is the common commercial replacement size; the 4-1/2 x 4 narrower leaf suits a thinner door or a shallower jamb rabbet. Corners are square on all of them, so they drop into a square-cornered mortise without re-routing.
3) Will the McKinney MP79 fit a mortise with radius corners?
No. The MP79 is a square corner hinge, so it needs a square cornered mortise. On a door or frame prepped with a radiused corner you would either have to chisel the pocket square or pick a radius hinge. For a 5/8 inch radius pocket, the Delaney exterior residential hinge is a 4 x 4 with a 5/8 inch radius; for a 1/4 inch radius, Orca Hardware makes a 4 x 4 x 1/4 inch radius corner commercial hinge.
4) What does NRP mean on a McKinney MP79 hinge and do I need it?
NRP is the non-removable pin option, a set screw in the barrel that stops the pin being driven out once the door is closed. Order it on any out-swinging door where the hinge barrel is on the outside, exterior doors, stairwells, storage rooms, anything an intruder could reach. On an in-swinging door the barrel is protected already and standard pin is fine. Both sizes and both finishes are offered with or without NRP.
5) I need a 4-1/2 x 4-1/2 ball bearing hinge for a heavy door. Is the McKinney MP79 the right one?
Not for a heavy door. The MP79 is standard duty and sized for standard weight doors. For heavy weight at the same 4-1/2 x 4-1/2 size, the Don-Jo HWBB74545 and HWBB84545 are heavy duty full mortise ball bearing hinges in satin chrome, and the Hager BB1168 is a heavy duty full mortise ball bearing hinge supplied with a non-removable pin. Solid core wood, wide leaf, or a closer on the door all point to those instead.
6) Can I run electrified hardware through a McKinney MP79 hinge for an access control door?
No. The MP79 is a plain mechanical butt hinge with no wire path through the barrel. To transfer power to an electric lock or strike through the hinge, use an electrified hinge: ZenSupply carries the BEST CECB179-12C full mortise concealed bearing electrified hinge with a 12-wire quick connect, and the Command Access ETH-CB70 3-knuckle standard weight energy transfer hinge. If you also need door position monitoring, the Command Access ETM-CB70 adds a door position sensor.
7) What is the closest equivalent to a McKinney MP79 standard weight full mortise hinge from another manufacturer?
The Stanley Security FBB191 is the nearest match. Like the McKinney MP79, it is a 5-knuckle full mortise standard weight hinge, and it is offered in 4.5 inch by 4.5 inch, the same size the MP79 covers alongside 4.5 inch by 4 inch. The MP79 is a ball bearing hinge with square corners in a steel base. If the opening is already prepped for a 4-1/2 inch square corner mortise, either drops into the same cutout.
8) The door has a closer on it - what should be used instead of a McKinney MP79?
The MP79 is built for standard weight, medium frequency doors, so an opening with a closing device is better served by a heavy duty hinge. The Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge in 4-1/2 inch by 4-1/2 inch with a satin chrome finish, matching the 626 satin chrome the MP79 is offered in, and the Ives 3CB1HW is a heavy weight concealed bearing full mortise hinge in steel. Both carry a heavy duty rating where the MP79 is standard duty.
9) What other 4-1/2 inch hinge comes with a non-removable pin like the McKinney MP79 NRP option?
The MP79 is offered with NRP in both 4.5 inch by 4 inch and 4.5 inch by 4.5 inch. Two peers carry it as part of the part number: the Deltana CSB45N is a 4-1/2 inch by 4-1/2 inch square hinge sold in pairs with a non-removable pin, and the Hager BB1168 is a non-removable pin full mortise ball bearing hinge that Hager rates heavy duty. For out-swinging exterior doors where the pin is reachable, all three address the same security concern.
10) The frame is only prepped on one leaf - can a McKinney MP79 still be used?
No. The MP79 is a full mortise hinge, which needs a mortise in both the door edge and the frame. Where only the frame is prepped and the hinge mounts to the face of the door, the Hager 1129 is a half mortise plain bearing commercial hinge in 4-1/2 inch standard weight steel. For a fully surface-applied condition, the Hager 990 STEEL is a full surface hinge, 3 inch by 4 inch with a welded tip.
11) Do McKinney MP79 hinges come with screws for both wood and hollow metal frames?
Both are covered. The MP79 ships with 1/2 inch #12-24 machine screws for hollow metal frames and 1-1/4 inch #12 wood screws for wood doors and jambs, so you can hang a wood door in a steel frame without sourcing separate fasteners.
12) Will a McKinney MP79 hinge let a door swing a full 180 degrees back against the wall?
Yes, McKinney recommends the MP79 for hanging a door for a 180 degree swing. That matters where a door has to lay flat against the adjacent wall, a corridor door held open, or a room where the leaf would otherwise block traffic. You still need clearance at the jamb and no trim in the path.
13) What is the difference between a ball bearing hinge like the McKinney MP79 and a plain bearing hinge?
Ball bearing knuckles carry bearings between the leaves so the door turns on rolling elements instead of steel rubbing on steel. That is what keeps a medium frequency door quiet and square over time. Plain bearing hinges are for lower traffic and lighter doors, and ZenSupply carries those too, for instance the Ives 1010RP residential plain bearing hinge or the Orca 4 x 4 square corner plain bearing commercial hinge. If the door sees daily traffic, stay with the ball bearing.
14) Does the McKinney MP79 hinge meet ANSI/BHMA standards?
Yes. McKinney states the MP79 conforms to ANSI/BHMA 156.1 and 156.7. Those are the hinge standards a facility spec typically calls out, so it satisfies a drawing note that asks for a BHMA conforming full mortise butt hinge.
15) Is there a heavier hinge with a 5 inch leaf if a 4-1/2 inch McKinney MP79 is undersized for the door?
Yes. The Don-Jo HWBB75045 is a heavy weight full mortise ball bearing hinge, 5 inch by 4-1/2 inch in steel with a satin chrome finish, and the Don-Jo HWBB85045 is a 5 inch by 4-1/2 inch heavy weight full mortise ball bearing hinge in brass with a satin chrome finish. Both keep the ball bearing and full mortise arrangement of the MP79 while adding leaf height and a heavy duty rating over the MP79's standard duty.
16) Is a plain bearing hinge the same thing as the McKinney MP79?
No. The MP79 uses ball bearings in the knuckle. Hinges such as the Orca Hardware 4040, a 4 inch by 4 inch square corner commercial hinge, and the Ives 1010RP steel residential hinge with square corners are plain bearing. They can share the same square corner profile and mortise footprint, so they look interchangeable in the cutout, but the bearing type is the difference to check before ordering against an MP79.
17) What is a simpler ball bearing hinge alternative in the same 4-1/2 inch square corner size?
The Orca Hardware 3535 is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge, so it shares the bearing type, corner style and size with the 4.5 inch by 4.5 inch McKinney MP79. Orca rates it medium duty. For a smaller opening, the Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners.
18) For a house or apartment interior door, is the McKinney MP79 the right hinge or is something else a better fit?
The MP79 is a standard duty steel hinge in 4.5 inch by 4 inch and 4.5 inch by 4.5 inch sizes. For a smaller residential leaf, the Delaney RH35xx is a 3-1/2 inch by 3-1/2 inch bulk steel interior residential hinge sold in pairs with a 5/8 inch radius corner, the Deltana DSB35 is a 3-1/2 inch by 3-1/2 inch square residential hinge sold in pairs, and the Schlage Residential S3P1010 is a 3.5 inch by 3.5 inch square corner plain bearing mortise hinge in a pack of three. Match the corner style to the existing mortise: the MP79 and the Deltana and Schlage options are square, the Delaney is radiused.
19) Does a concealed bearing hinge work in place of a McKinney MP79?
They mortise the same way but the knuckle differs. The MP79 has 5 knuckles with the ball bearings visible between them. The Ives 3CB1 is a 3-knuckle concealed bearing full mortise hinge in steel, and the Hager 920 is a 2-knuckle full mortise concealed bearing hinge in steel construction. Both hide the bearing inside the barrel, so the knuckle count and the look of the exposed barrel change even when the cutout does not.
20) For a detention or high-abuse opening, what replaces the McKinney MP79?
The MP79 is a standard duty hinge and is not the part for a detention opening. The BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge, and the Stanley Security BB855 is a double weight prison hinge in 5 inch by 6 inch, furnished with no holes and not swaged, so it can be prepped to the frame on site. Both are rated heavy duty.
21) Which hinge handles a hardwired electrified opening that also needs a handed, standard weight 4-1/2 inch leaf?
The Stanley Security CECB1900R54L is a three knuckle concealed bearing concealed conductor architectural hinge, steel full mortise, standard weight, 4-1/2 inch by 4-1/2 inch, square corner, left-handed, 4-wire. It shares the 4.5 inch by 4.5 inch square corner steel full mortise footprint of the McKinney MP79 but routes conductors through the hinge, which the MP79 does not do, and it is handed where the MP79 is not.
22) Can the McKinney MP79 be painted to match my door and frame?
That is what the 600 primed finish is for. It arrives primed and ready to take paint, so a hinge on a field-painted hollow metal frame can be finished to match. If you want a plated finish out of the box instead, the 626 satin chrome option is the standard commercial look and needs no finishing.
23) When does a pivot make more sense than a McKinney MP79 hinge?
When the leaf swings both ways or the load is carried at the top and bottom of the door rather than on the edge. The BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors, and the BEST CB1969R is a concealed bearing heavy weight pivot-reinforced hinge. The MP79 is a full mortise hinge for standard weight doors hung on the door edge and is not a double acting device.
24) What is the difference between a McKinney MP79 and the Emtek heavy duty hinges in square corner?
Size and bearing. The MP79 is a 5-knuckle steel hinge in 4.5 inch by 4 inch and 4.5 inch by 4.5 inch with ball bearings. Emtek's square corner heavy duty hinges are 3-1/2 inch by 3-1/2 inch pairs in plated steel: the 94013 is ball bearing, while the 92013 is plain bearing and the 91013 is a residential plain bearing pair. The 3-1/2 inch leaf will not fill a 4-1/2 inch mortise, so the sizes are not interchangeable.
