McKinney T4A3386 4-1/2x4-1/2 26D – Frequently Asked Questions

1) Will a McKinney T4A3386 hinge work on a hollow metal frame with a hollow metal or wood door?
That is exactly the condition it is built around. The T4A3386 is a full mortise hinge, so one leaf mortises into the door edge and the other into the frame rabbet. McKinney calls out the flush door, frame and wall condition using a hollow metal frame with a standard hollow metal or wood door sitting flush or 1/16 inch inset from the face of the frame, and a full mortise hinge is the recommendation there for a 180 degree swing. The same hinge works with a wood or aluminum frame provided the door, frame and wall conditions are flush. If the wall projects past the face of the frame, or the door is not flush or inset, this is not the hinge for that opening.
2) My door and frame are prepped with square corner hinge pockets. Will the McKinney T4A3386 drop straight in?
Square corner prep is what the T4A3386 is cut for, so it seats in an existing square pocket with no chisel work, as long as the leaf size matches. It comes in 4-1/2 x 4-1/2, 5 x 4-1/2 and 5 x 5. Pull one of the old hinges and measure the leaf before you order. A square corner hinge will not sit properly in a radius corner mortise, and a radius hinge leaves a gap at the corners of a square pocket, so radius prep needs a radius corner hinge instead.
3) The hinge edge of my door is beveled. Is the McKinney T4A3386 still the right hinge?
No, the T4A3386 is not the beveled edge model. Where doors are beveled on the hinge side, McKinney specifies T4A4386 or T4A4786. Same five knuckle heavy weight full mortise family, cut for the bevel. Ordering the T4A3386 for a beveled hinge edge leaves the leaf sitting proud at one edge of the mortise.
4) What is the difference between the McKinney T4A3386 and the T4A3786?
Base material. The T4A3386 has a stainless steel base and is also offered in a polished brass base material; the T4A3786 is a steel base hinge. Beyond that they are the same five knuckle heavy weight full mortise series. For exterior openings, coastal or humid buildings, pool areas and wash down spaces, the stainless base is the one that will not rust out at the knuckles. Steel base is the normal pick for protected interior commercial openings.
5) I am hanging an outswing exterior door. Can someone pull the pin out of a McKinney T4A3386?
Order it with the non-removable pin option and they cannot. On an outswing door the hinge barrel sits on the outside, so a standard pin can be driven up and out and the door lifted off with the lock still thrown. The NRP option puts a set screw in the barrel that bears on the pin and is only reachable with the door open. Use it on any opening where the barrel ends up on the unsecured face. If you need a second source for the same thing, the Hager BB1168 is a full mortise ball bearing heavy duty hinge supplied with a non-removable pin.
6) What is the closest cross-brand equivalent to a McKinney T4A3386 in a 4-1/2 by 4-1/2 heavy weight ball bearing hinge?
The McKinney T4A3386 is a heavy duty five knuckle full mortise ball bearing hinge with square corners, and 4-1/2 by 4-1/2 is one of the sizes it is built in. The nearest match from another maker is the Don-Jo HWBB74545, a heavy weight full mortise ball bearing hinge in 4-1/2 by 4-1/2 with a satin chrome finish, or the Don-Jo HWBB84545, the same heavy weight full mortise ball bearing type at 4-1/2 by 4-1/2 in satin chrome. Both Don-Jo hinges carry a heavy duty rating, so they sit in the same weight class as the T4A3386 for the same mortise size. Confirm corner style against the existing prep before you swap, since the McKinney is square corner.
7) The opening needs power to the door for an electric lock. Can I use a McKinney T4A3386 or do I need a different hinge?
A McKinney T4A3386 is a mechanical heavy duty five knuckle ball bearing full mortise hinge, so power has to come from a separate transfer device. If you would rather run the wire through the hinge itself, the Command Access ETH-BB68 is an energy transfer hinge with a five knuckle heavy duty steel base, which keeps the same knuckle count and weight class as the McKinney. The BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect for openings that need more conductors, and the Stanley CECB1900R54L is a three knuckle concealed bearing concealed conductor hinge, steel full mortise, standard weight, 4-1/2 by 4-1/2, square corner, left handed, with 4 wires - note that one is handed and must be ordered to match the door. Count your conductors first: strike, lock, monitoring and REX each consume wires.
8) I need a 5 by 4-1/2 heavy weight ball bearing hinge and I am not tied to McKinney. What else fits?
The McKinney T4A3386 is built in 5 inch by 4-1/2 inch as a heavy duty five knuckle ball bearing full mortise hinge. In the same size and function, the Don-Jo HWBB75045 is a heavy weight full mortise ball bearing hinge at 5 inch by 4-1/2 inch in steel with a satin chrome finish, and the Don-Jo HWBB85045 is a heavy weight full mortise ball bearing hinge at 5 inch by 4-1/2 inch in brass with a satin chrome finish. Both are rated heavy duty. The steel and brass bases are the practical difference between the two Don-Jo numbers, which matters where the opening is exposed to weather or a corrosive environment.
9) Which heavy duty ball bearing hinges come with a non-removable pin already, next to the McKinney T4A3386?
For an outswing door where the barrel is on the unsecured side, the Hager BB1168 is a non-removable pin full mortise ball bearing hinge rated heavy duty in the BB1168 series, which is the same full mortise ball bearing construction as the McKinney T4A3386. The Deltana CSB45N is a 4-1/2 by 4-1/2 square hinge sold as a pair with a non-removable pin, matching the square corner and 4-1/2 by 4-1/2 size the T4A3386 is built in. The Deltana DE44R5TA is a 4 by 4 security hinge with a 5/8 inch radius in steel, sold as a pair, for openings prepped with radius corners rather than square.
10) Do I need a heavy weight hinge, or will a standard commercial ball bearing hinge handle my door?
Heavy weight is the call for extra heavy doors and any door exposed to high frequency use, which is McKinney's own criterion for the T4A3386. That means a lead lined or thick solid core leaf, a wide 4 foot door, or a stairwell, entry or corridor door that cycles all day. For an ordinary interior office or classroom door on normal traffic, a medium duty ball bearing hinge does the job, such as the Orca Hardware 3535 Series 4-1/2 x 4-1/2 square corner ball bearing hinge. Plain bearing construction like the Orca 4040 Series 4 x 4 square corner is simpler again and suits light, low cycle interior doors. Ball bearings are what keep a heavy leaf from sagging and starting to drag on the strike jamb over time.
11) I need to standardize hinge finish across a building. What sizes and finishes does the McKinney T4A3386 come in?
Three sizes and nine finishes, and every finish is offered in every size, so one finish can carry across doors that take different hinge sizes. Sizes: 4-1/2 x 4-1/2, 5 x 4-1/2 and 5 x 5. Finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil rubbed, US10A antique bronze, 625 bright chrome, 626 satin chrome, 629 bright stainless steel and 630 satin stainless steel. 626 and 630 are the two that usually line up with commercial levers, closers and exit devices already in a building.
12) What is the difference between the McKinney T4A3386 and a concealed bearing hinge like the Ives 3CB1HW?
The McKinney T4A3386 is a five knuckle ball bearing full mortise hinge rated heavy duty, so the bearings sit between the knuckles and are visible in the barrel. The Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with three knuckles, also rated heavy duty, where the bearing is hidden inside the knuckle for a smoother barrel line. The BEST CB1969R is another concealed bearing heavy weight hinge, pivot reinforced, rated heavy duty. If the door is lighter, the Ives 3CB1 is a three knuckle concealed bearing full mortise hinge rated medium duty, and the Hager 920 is a two knuckle concealed plain bearing full mortise hinge, also medium duty. Knuckle count changes the look of the barrel on an exposed edge, so match it across the openings on the same elevation.
13) Is there a hinge that reports door position instead of just carrying the door like the McKinney T4A3386 does?
The McKinney T4A3386 is a mechanical heavy duty ball bearing full mortise hinge with no switch in it. When the access control system needs a door position input from the hinge, 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, which is the closest weight match to the T4A3386. The Command Access ETM-CB70 is an energy transfer monitor hinge with door position sensing on a three knuckle steel base, rated medium duty, for lighter leaves. If the door only needs power and no status contact, the Command Access ETH-BB68 energy transfer hinge with a five knuckle heavy duty steel base covers that.
14) The door is an interior office leaf that gets normal traffic. Do I need the McKinney T4A3386 or is there a lighter hinge in the same 4-1/2 inch square corner size?
Heavy weight hinges like the McKinney T4A3386 are meant for extra heavy doors or those exposed to high frequency use, and the T4A3386 is a heavy duty five knuckle ball bearing full mortise hinge in a 4-1/2 by 4-1/2 square corner size. For a lighter leaf in the same mortise, the Orca Hardware COM3535 is a 4-1/2 by 4-1/2 square corner ball bearing commercial hinge rated medium duty, and the Stanley FBB191 is a five knuckle full mortise standard weight hinge at 4-1/2 by 4-1/2. Both keep ball bearing or five knuckle full mortise construction at the same leaf size, so the prep does not change - only the weight class does.
15) The existing hinge prep has rounded corners, so a McKinney T4A3386 will not drop in. What matches a radius corner mortise?
The McKinney T4A3386 is a square corner hinge, so it needs a square prep or a filed mortise. For radius prep, the Orca Hardware COM4014 is a 4 by 4 hinge with a 1/4 inch radius corner in plain bearing, rated medium duty, and the Orca Hardware COM3514 is a 3-1/2 by 3-1/2 hinge with a 1/4 inch radius corner in plain bearing, also medium duty. Where the prep uses the larger 5/8 inch radius, the Deltana DE44R5TA is a 4 by 4 hinge with a 5/8 inch radius in steel sold as a pair, and the Delaney RH45xx is a 4 by 4 exterior hinge with a 5/8 inch radius, also a pair. Measure the corner radius in the existing mortise before ordering - 1/4 inch and 5/8 inch preps are not interchangeable.
16) Can I use a residential ball bearing hinge in place of a McKinney T4A3386?
They look similar in a photo but they are not the same class of part. The McKinney T4A3386 is a commercial heavy duty five knuckle ball bearing full mortise hinge built in 4-1/2 by 4-1/2, 5 by 4-1/2 and 5 by 5. The Emtek 94013 is a heavy duty ball bearing hinge sold as a pair at 3-1/2 by 3-1/2 with square corners in plated steel, and the Emtek 91013 is a residential plain bearing hinge, also a pair at 3-1/2 by 3-1/2. The Schlage Residential S3P1010 is a 3.5 by 3.5 square corner plain bearing mortise hinge in a pack of three, rated medium duty, and the Ives 1010RP is a steel plain bearing residential hinge with square corners in a set of three, also medium duty. The size gap alone rules them out for a commercial 4-1/2 or 5 inch prep, and they are counted in pairs or sets rather than singly.
17) The frame will not take a full mortise leaf. What replaces a McKinney T4A3386 on that opening?
The McKinney T4A3386 is a full mortise hinge, which means both leaves mortise into the door and the frame. Where the frame cannot be prepped, the Hager 1129 is a half mortise commercial hinge in plain bearing at 4-1/2 inch standard weight steel, rated heavy duty, so one leaf mortises and the other surface applies. For a fully surface applied condition on an abuse resistant opening, the Hager 990 STEEL is a full surface prison hinge at 3 by 4 with a welded tip, rated heavy duty. Both change the door and frame prep, so confirm the leaf pattern against the existing holes before you commit.
18) Is a McKinney T4A3386 enough for a detention or high abuse opening, or do I need a detention hinge?
The McKinney T4A3386 is a heavy duty five knuckle ball bearing full mortise hinge intended for extra heavy doors or those exposed to high frequency use, which covers commercial traffic. Detention openings use a different family: the BEST BB855 is a heavy duty steel double weight concealed ball bearing prison hinge in the detention hardware series, and the Stanley BB855 is a double weight prison hinge at 5 by 6, furnished with no holes and not swaged, rated heavy duty, so it is machined to the frame shop's pattern rather than drilled to a standard template. Double weight and the unmachined leaf are the practical differences from the commercial heavy weight T4A3386.
19) The door has to close itself. Is there a self-closing hinge that fits the same prep as a McKinney T4A3386?
A McKinney T4A3386 is a heavy duty ball bearing full mortise hinge with no closing force in it, so a self-closing door needs either a closer or a spring hinge. The Stanley 2060R is a full mortise spring hinge with square corners at 4.5 by 4.5 on a ferrous steel base, rated heavy duty - the same square corner, 4-1/2 by 4-1/2 full mortise footprint the T4A3386 is built in, so the door and frame prep carries over. Spring hinges are commonly installed with plain hinges in the same opening, so you may be ordering both.
20) Can I use 3-1/2 inch residential hinges on a commercial door instead of a heavy weight hinge?
Not on the openings the T4A3386 is meant for. It is a commercial heavy duty hinge and its smallest leaf is 4-1/2 x 4-1/2, so a 3-1/2 inch residential hinge will not fill the mortise on a commercially prepped door. Hinges like the Emtek 91013 and 92013 at 3-1/2 x 3-1/2 are plain bearing residential duty, and the Delaney 3-1/2 x 3-1/2 bulk interior hinges and Deltana DSB35 are residential as well. They are built for a light interior leaf, not a heavy door on a high cycle opening.
21) What do I have to specify when ordering a McKinney T4A3386 hinge?
Two choices: size and finish. Size is 4-1/2 x 4-1/2, 5 x 4-1/2 or 5 x 5, and there are nine finishes, with every finish available in every size. There is no left or right hand to call out on the order. Add the non-removable pin option if the barrel will end up on the unsecured face. Two things send you to a different model number rather than an option: a door beveled on the hinge edge takes T4A4386 or T4A4786, and a steel base instead of stainless or brass is the T4A3786.
22) What is the difference between the McKinney T4A3386 and a plain bearing commercial hinge of the same size?
The McKinney T4A3386 uses ball bearings between the knuckles and is rated heavy duty, which is the construction called for on extra heavy doors or doors exposed to high frequency use. A plain bearing hinge has no bearing between the knuckles: the Orca Hardware COM4040 is a 4 by 4 square corner plain bearing commercial hinge rated medium duty, and the Emtek 92013 is a heavy duty plain bearing hinge sold as a pair at 3-1/2 by 3-1/2 with square corners in plated steel. The Hager 1129 is a plain bearing commercial hinge at 4-1/2 inch standard weight steel in a half mortise pattern. Bearing type and cycle expectation move together, so match it to the traffic the opening actually sees.
23) The door needs to swing both directions. Will a McKinney T4A3386 work?
No - the McKinney T4A3386 is a full mortise hinge, the type recommended to hang a door for a 180 degree swing in one direction. A door that swings both ways runs on pivots instead: the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors, in the emergency rescue hardware series. That is a different prep at the head and floor rather than a leaf mortise in the door edge, so it is a design decision on the opening, not a drop-in swap.
