McKinney TA2774 4-1/2 26D – Frequently Asked Questions

1) What is a half mortise hinge and when would I use the McKinney TA2774 instead of a full mortise hinge?
On a half mortise hinge like the McKinney TA2774, only one leaf gets mortised. The door leaf is mortised into the edge of the door, and the jamb leaf is applied to the surface of the jamb with machine screws. That makes it the choice when you cannot cut a mortise into the frame, most commonly channel iron jambs, which the TA2774 is specifically called out for. If both your door edge and your frame are prepped for mortised leaves, you want a full mortise hinge instead, such as the Stanley FBB191 5-knuckle full mortise standard weight hinge in 4.5 x 4.5.
2) What size and how many McKinney TA2774 hinges do I need for my door?
The TA2774 is a 4.5 inch hinge, and that is the only size offered. It is a standard weight, medium frequency hinge, rated for average frequency or medium weight wood and metal doors in public buildings with medium traffic. If your opening is a heavy door, high traffic, or an oversized leaf, step up to a heavy weight hinge rather than adding more of these. Hinges are sold individually here, so order per leaf count for the opening.
3) My door has a beveled edge on the hinge side. Will the McKinney TA2774 work?
No. The TA2774 is for square-edge doors. Where the door is beveled on the hinge side, McKinney calls for the TA4374 or TA4774 instead. Ordering the TA2774 for a beveled opening means the door leaf will not sit correctly in the mortise.
4) Is the pin on the McKinney TA2774 removable, and do I need NRP for an outswing exterior door?
The pin is held by an NRP set screw, and NRP (Non-Removable Pin) is offered as an option when ordering. On any outswing door where the hinge barrel is exposed on the secure side, specify NRP so the pin cannot be driven out and the door lifted off. For interior inswing openings it is not required. Hospital tip is also available if you need the barrel without a protruding tip.
5) Is the McKinney TA2774 ball bearing or plain bearing, and does it matter if the door has a closer?
Ball bearing. That is what you want on any door carrying a closer, because a closer works the hinge on every cycle and a plain bearing wears faster under that load. McKinney lists the TA2774 as recommended for doors with closing devices and for 180 degree swing. If you are replacing a plain bearing half mortise hinge, the Hager 1129 is the plain bearing half mortise equivalent in 4.5 inch steel.
6) What is the closest half mortise hinge to a McKinney TA2774 if I need a plain bearing version?
The Hager 1129 is a half mortise commercial hinge in 4-1/2 inch standard weight steel with a plain bearing. The McKinney TA2774 is a 5-knuckle standard weight half mortise hinge in steel at 4.5 inch with a ball bearing. Both mount the same way - door leaf mortised into the door edge, jamb leaf applied to the face of the jamb - so the opening prep is the same; the difference is the bearing and the Hager carries a heavy duty level.
7) The door is heavier and higher traffic than standard weight - what heavy weight hinge should I look at instead of a TA2774?
The McKinney TA2774 is a standard duty hinge recommended for average frequency and medium weight wood or metal doors. For a heavier leaf, the Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge at 4-1/2 inch by 4-1/2 inch, and the Don-Jo HWBB75045 is a heavy weight full mortise ball bearing hinge at 5 inch by 4-1/2 inch. Both are full mortise, so the frame needs hinge prep rather than the surface-applied jamb leaf the TA2774 uses.
8) Can the McKinney TA2774 be used on both left-hand and right-hand doors?
Yes, it is reversible, so one part number covers either hand. That matters for a property manager stocking spares across a building: you carry one hinge, not two. Pick the finish to match the rest of the openings and the same hinge hangs either way.
9) Does the McKinney TA2774 come with screws, and what size are they?
Mounting screws come with the hinge: 1/2 inch #12-24 machine screws and 1-1/4 inch #12 wood screws. The machine screws go through the jamb leaf into the frame (the jamb leaf mounts to the surface), and the wood screws serve the mortised door leaf on a wood door. On a metal door you will be tapping for machine screws rather than using the wood screws.
10) What is the difference between the McKinney TA2774 and the TA3374?
Material. The TA2774 is steel; the TA3374 is the stainless steel version of the same five knuckle standard weight half mortise hinge. Both carry the same duty recommendation. Take stainless for exterior, coastal, or wash-down openings where corrosion is the concern, and the steel TA2774 for interior commercial work.
11) I need an electrified hinge to power a lock through the door. Can the McKinney TA2774 do that?
No, the TA2774 is a mechanical hinge with no wire transfer. For getting power through the opening you need an energy transfer hinge: the Command Access ETH-BB68 is a 5-knuckle heavy duty steel base transfer hinge, the ETH-CB70 is the 3-knuckle standard weight version, and the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect. If you also need door position monitoring, the Command Access ETM-BB68 adds an integrated door position switch.
12) Can I use a residential hinge like the Delaney 3-1/2 inch instead of a McKinney TA2774?
They are built for different doors. The Delaney RH35 is a 3-1/2 inch by 3-1/2 inch bulk steel residential interior hinge with a 5/8 inch radius corner, sold in pairs. The McKinney TA2774 is a commercial hinge at 4.5 inch with square corners and a ball bearing, intended for medium weight wood or metal doors in public buildings. The corner style and size alone mean the Delaney will not drop into a TA2774 mortise.
13) What 4-1/2 inch square corner ball bearing commercial hinge is the closest match to a TA2774 for a fully prepped door and frame?
The Orca Hardware 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge with a medium duty rating. That matches the McKinney TA2774 on size, corner style, and ball bearing, with the difference being that the TA2774 is the half mortise form with the jamb leaf applied to the jamb surface and the door leaf mortised into the door edge.
14) Will a spring hinge work in place of a TA2774 to close the door?
The Stanley Security 2060R is a full mortise square corner spring hinge at 4.5 inch by 4.5 inch on a ferrous steel base with a heavy duty rating, and it self-closes the door. The McKinney TA2774 has no spring; it is recommended for doors with separate closing devices and for hanging a door for a 180 degree swing. If the opening already has a closer, the TA2774 is the hinge that suits it.
15) For a detention or high-abuse opening, is the TA2774 the right hinge or do I need something else?
Step up to a detention hinge. The BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge, the Stanley BB855 is a double weight prison hinge at 5 inch by 6 inch furnished with no holes and not swaged, and the Hager 990 STEEL is a full surface prison hinge at 3 inch by 4 inch with a welded tip, heavy duty. The McKinney TA2774 is a standard duty hinge for average frequency and medium weight doors in medium traffic public buildings.
16) What finishes does the McKinney TA2774 half mortise hinge come in?
Eight finishes across the 4.5 inch size: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, US10A antique bronze, 625 bright chrome, 626 satin chrome, and 600 primed for painting. The 600 is the one to take when the hinges are getting field-painted to match a frame color, and 626 satin chrome is the usual match for commercial lever and closer hardware already in most buildings.
17) Is the McKinney TA2774 suitable for a residential door?
It is built for commercial use, and it is a half mortise hinge, which is not a prep you find on residential openings. For a house, a full mortise residential hinge is the right part: the Emtek 91013 residential plain bearing pair in 3-1/2 x 3-1/2 square corner plated steel, the Schlage S3P1010 3.5 x 3.5 square corner pack of three, or the Delaney 4 x 4 exterior residential hinges with a 5/8 inch radius.
18) How many knuckles does the McKinney TA2774 have, and does knuckle count matter for matching existing hinges?
Five knuckles. Knuckle count is visible on the finished opening, so if the rest of the doors on a floor are running five knuckle hinges, a three knuckle replacement will read as a mismatch even where it functions fine. It also changes the barrel pattern, so a hospital tip or NRP detail lines up the way the adjacent openings do.
19) Is the Deltana CSB45N the same thing as a McKinney TA2774 since both offer a non-removable pin?
No. The Deltana CSB45N is a 4-1/2 inch by 4-1/2 inch square hinge sold in pairs with a non-removable pin. The McKinney TA2774 is a 5-knuckle half mortise hinge in steel with a ball bearing, sold for commercial openings, and its pin is held by an NRP set screw. The NRP feature is shared; the mortise prep is not, since the TA2774 jamb leaf mounts to the jamb surface with 1/2 inch #12-24 machine screws.
