McKinney MPB79 MacPro Hinges, 5-Knuckle, Standard Weight

Yes. The MPB79 is recommended for standard weight, medium frequency doors or doors with closing devices. It's a ball bearing hinge, which is what carries the extra load a closer puts on the pivot point. If the door itself is heavy weight rather than standard weight, this is the wrong hinge, and the Don-Jo HWBB84545 in 4-1/2 x 4-1/2 is a heavy weight full mortise ball bearing option in the same size.

On any outswing door where the hinge barrel is on the unsecured side, yes. The MPB79 is offered with a non-removable pin as an ordering option on both the 626 satin chrome and 600 primed versions, so pick the NRP variant rather than adding anything in the field. Inswing doors don't need it. If you want NRP in a heavy duty hinge instead, the Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge.

Yes, by adding the QC8 Quick Connect 8-Wire option when you order. Eight conductors is enough for a typical electric latch retraction or lock power plus monitoring run. If you need more circuits, the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect, and the Command Access ETM-CB70 adds an integrated door position sensor for monitoring the opening.

The MPB79 is a full mortise hinge at 4-1/2 x 4-1/2 with square corners, so it drops into an existing square corner mortise of that size without re-routing the jamb or door edge. If your existing cutouts have radius corners instead, this is the wrong corner style and you'd need a radius corner hinge such as the Orca Hardware 4014 Series at 4 x 4 with a 1/4 inch radius.

The Stanley Security FBB191 is the nearest match in form: a 5-knuckle full mortise standard weight hinge in 4-1/2 by 4-1/2, the same size the MPB79 MacPro is built in. Both are full mortise hinges that mortise into the door edge and frame rabbet, so the prep is the same cutout. The MPB79 is a ball bearing hinge in steel with square corners, which matters if the existing frame prep is square rather than radiused - a square corner hinge will not sit correctly in a radiused mortise without rework, and vice versa.

Step up to a heavy duty ball bearing hinge in the same 4-1/2 by 4-1/2 footprint. The Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge in 4-1/2 by 4-1/2 with a satin chrome finish, and the Hager BB1168 is a heavy duty full mortise ball bearing hinge furnished with a non-removable pin. The McKinney MPB79 is a standard duty hinge recommended for standard weight, medium frequency doors or doors with closing devices, so on a high traffic opening with an aggressive closer the heavier bearing hinges carry the cycle load differently. All three mortise into the door edge and frame, so the change is a hinge swap rather than a frame change, provided the corner style and size match what is already cut.

An electrified or energy transfer hinge carries the wiring from frame to door in place of one standard hinge in the set. The Command Access ETH-BB68 is a 5-knuckle heavy duty energy transfer hinge on a steel base, matching the 5-knuckle form of the McKinney MPB79, while the ETH-CB70 is the 3-knuckle standard weight version. The BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect. If door position monitoring is also needed, the Command Access ETM-BB68 combines the energy transfer with an integrated door position switch. The MPB79 itself can be ordered with a QC8 quick connect 8-wire option, so the choice is whether the wire count and monitoring the opening needs are covered by that.

The Orca Hardware 3535 series is a 4-1/2 by 4-1/2 square corner ball bearing commercial hinge rated medium duty, matching the McKinney MPB79 MacPro on size, corner style, and bearing type. The MPB79 is a 5-knuckle steel hinge that conforms to ANSI/BHMA 156.1 and 156.7, and MPB79 is approved for NFPA 80 fire-rated openings, so on a rated opening the fire approval is the deciding factor rather than the size match. For a non-rated interior opening where the prep is 4-1/2 square corner, both fit the same mortise.

A spring hinge. The Stanley Security 2060R is a full mortise spring hinge with square corners in 4-1/2 by 4-1/2 on a ferrous steel base, rated heavy duty. It occupies the same full mortise 4-1/2 by 4-1/2 square corner prep the McKinney MPB79 MacPro uses, so the frame and door cutouts carry over. The MPB79 is a ball bearing hinge with no self-closing action of its own and is recommended for use on doors with separate closing devices.

One size, 4-1/2 x 4-1/2 inches with square corners, in two finishes: 626 satin chrome and 600 primed for painting. Each finish is offered with or without the non-removable pin, so there are four combinations to pick from. The 600 primed option is the one to take if the doors are being field painted to match a frame color.

Both machine and wood screws are furnished: 1/2 inch #12-24 machine screws for the hollow metal frame leaf, and 1-1/4 inch #12 wood screws for a wood door leaf. That covers the usual hollow metal frame with a wood door combination without a separate fastener order.

That's what it's set up for. The MPB79 is recommended to hang a door for a 180 degree swing, which matters where a corridor or classroom door has to lay back flat against the adjacent wall. Five knuckles and ball bearings handle the repeated travel.

They solve different problems. The MPB79 is a 5-knuckle full mortise hinge with exposed ball bearings between the knuckles, which is the traditional commercial look and gives you more bearing surface. A concealed bearing hinge like the Ives 3CB1 hides the bearings inside the knuckles for a cleaner barrel and less dirt catching, at medium duty. Pick the 5-knuckle where you're matching existing hinges on the other openings; pick concealed where appearance or a wipe-down environment matters.

Steel base material with ball bearings, rated standard duty and recommended for medium frequency doors. For an office suite, a residential corridor, or a light-use interior opening that's the right level. For a stairwell, a main entry, or anything cycling constantly, step up to a heavy weight hinge such as the Don-Jo HWBB84545 at 4-1/2 x 4-1/2 or the Ives 3CB1HW heavy weight concealed bearing hinge.

No. The MPB79 MacPro is a ball bearing hinge, where bearings sit between the knuckles to carry the door weight as the leaf turns. Plain bearing hinges such as the Orca Hardware 4040 in 4 by 4 square corner and the Hager 1129 half mortise run knuckle against knuckle with no bearing. They fit the same style of opening and can look nearly identical in a catalog photo, but they are a different bearing type, and on a door with a closer the ball bearing construction is what the MPB79 is recommended for. The Hager 1129 is also half mortise rather than full mortise, so it mortises into the door and surface mounts to the frame - a different prep entirely from the MPB79.

Knuckle count and how the bearing is presented. The McKinney MPB79 MacPro is a 5-knuckle hinge with ball bearings visible between the knuckles. The Ives 3CB1 is a 3-knuckle concealed bearing full mortise hinge rated medium duty, and the Ives 3CB1HW is the heavy weight version of that same 3-knuckle concealed bearing design. Concealed bearing hides the bearing inside the barrel, which gives a smoother uninterrupted knuckle line. Both mortise into the door edge and frame, so on a specification that calls out knuckle count or bearing style by name, the two are not interchangeable even at the same size.

They solve different levels of the same concern. The MPB79 with the non-removable pin option prevents the pin from being pulled on a door where the barrel is exposed. Detention and security hinges go further: the BEST BB855 is a heavy duty steel double weight concealed ball bearing prison hinge, the Hager 990 STEEL is a full surface prison hinge 3 by 4 with a welded tip, and the Deltana DE44R5TA is a 4 by 4 security hinge with a 5/8 inch radius in steel. The Hager 990 is full surface, meaning it mounts to the face of the door and frame rather than mortising in like the MPB79, so it is a different prep and typically a different opening type.

Only on an opening designed for it. A pivot carries the door at the top and bottom rather than along the edge, so it is a different frame and floor prep from the full mortise MPB79 MacPro. The BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors, which lets a door swing both directions - something a full mortise hinge cannot do. The BEST CB1969R is a concealed bearing heavy weight pivot-reinforced hinge, a middle ground that keeps hinge mounting while adding pivot reinforcement. The MPB79 is recommended to hang a door for a 180 degree swing in one direction.

It decides whether the hinge sits flat in the mortise. The McKinney MPB79 MacPro has square corners, matching square corner peers such as the Delaney CH401X 4 by 4 commercial ball bearing hinge with square corner and the Orca 4040 4 by 4 square corner commercial hinge. Radius corner hinges such as the Orca 4014 4 by 4 with a 1/4 inch radius corner and the Delaney 4 by 4 exterior residential hinge with a 5/8 inch radius are cut for a rounded mortise. A square hinge in a radiused pocket leaves gaps at the corners and a radiused hinge in a square pocket does not fill it, so confirm the existing mortise before substituting.

Both. McKinney is ASSA ABLOY's architectural hinge line and has been part of that family since 1996. Ordering by the McKinney model MPB79 gets you the MacPro 5-knuckle standard weight full mortise hinge; that model designation is what a distributor or spec writer should reference.

Hinges are sold and specified per hinge here, not in pairs, so order the quantity your opening needs. Standard trade practice is three hinges on a 7 foot door and a fourth on anything taller. The MPB79 is a single 4-1/2 x 4-1/2 hinge per unit, unlike some residential lines that ship as a pair.
