McKinney TCA2314 Square Corner 5 Knuckle Full Mortise Hinge, 4-1/2" by 4-1/2"

It's a standard duty hinge, rated by McKinney for standard weight doors, medium frequency openings, or doors carrying a closer. A high-traffic entrance or a heavy door wants a heavy weight hinge instead - the BEST CB223 concealed bearing hinge and the Dormakaba/Stanley CB199 are both heavy duty options, and the Hager WTBB1168 is a heavy weight 5-knuckle if you also need wide throw.

The TCA2314 is a 4-1/2 inch by 4-1/2 inch square corner hinge, which is the standard commercial mortise size on a 1-3/4 inch door. If the existing hinge pockets are 4-1/2 x 4-1/2 with square corners, it drops straight in. If your frame is routed with radius corners, you need a radius corner hinge, not this one.

Add the NRP (Non-Removable Pin) option when you order the TCA2314 and the pin can't be driven out once the door is closed. That matters on any out-swinging exterior or storage door where the barrel is on the unsecure side. McKinney also offers a Safety Stud Feature on this hinge for the same reason.

No. The TCA2314 is built for common flush door, frame and wall applications with square corners; McKinney specifies the TCA4314 in stainless or TCA4714 in steel for doors beveled on the hinge side. If you are working a beveled edge door in heavy weight, the BEST CB223 is a stainless concealed bearing heavy weight pivot reinforced hinge made specifically for beveled edge doors.

McKinney offers electrified options in the TCA2314 family, so specify the electrified variant rather than the standard hinge. A comparable off-the-shelf route is the ACSI 5BB1, a five knuckle ball bearing full mortise hinge at 4-1/2 inch by 4-1/2 inch with a concealed electric through-wire, four wire at 28 gauge, in the 1100 Series. Match the number of conductors to what the lock or exit device draws.

No. The TCA2314 is a standard full mortise hinge for flush door, frame and wall applications and does not move the door leaf clear of the frame. For clear opening width, use a swing clear hinge: the BEST CB248 is a steel full mortise concealed bearing swing clear hinge for square edge doors, medium duty, and the Hager 1260 is a full mortise swing clear hinge with a five knuckle plain bearing design in heavy duty.

The Don-Jo BB94545 is the nearest match in stainless: a full mortise ball bearing hinge at 4-1/2 inch by 4-1/2 inch with square corners, rated standard duty. The TCA2314 is also a stainless steel full mortise hinge at 4-1/2 inch by 4-1/2 inch with square corners and standard duty rating, using a five knuckle concealed anti-friction bearing barrel. The difference is bearing style - the McKinney uses concealed bearings, the Don-Jo uses exposed ball bearings between the knuckles.

The Don-Jo BB74545 is a steel full mortise ball bearing hinge, 4-1/2 inch by 4-1/2 inch, square corner, five knuckle, standard duty - the same footprint and prep as the stainless TCA2314. McKinney's own steel counterpart in the same family is the TCA2714. For interior openings where corrosion is not a concern, the steel version drops into the identical mortise.

The TCA2314 is a standard duty hinge recommended for standard weight, medium frequency doors or doors with closing devices. For heavier leaves, the Stanley Security CB199 is a full mortise concealed bearing heavy weight hinge in the Architectural Hinges series, and the BEST FBB212 is a steel ball bearing heavy weight pivot reinforced hinge for square edge doors. Both step up the load rating while keeping a full mortise prep.

Fasteners are specified as 1/2 in x #12-24 machine screws for the frame side and 1-1/4 in x #12 wood screws for wood doors. That covers both hollow metal frame and wood door mounting, so you can spec it on a mixed opening without sourcing separate screws.

Same hinge, different base metal. The TCA2314 is stainless steel and the TCA2714 is steel; both are concealed anti-friction bearing, five knuckle, standard weight full mortise hinges. Go stainless on exterior openings, coastal sites, kitchens, and wash-down areas where a plated steel hinge will rust at the barrel.

Yes, McKinney recommends hanging the door for a 180 degree swing with the TCA2314. You still need the hinge barrel to clear the trim or wall return on the opening - the hinge allows it, the jamb condition decides it.

No. It's a five knuckle full mortise hinge with a removable pin, so the same hinge hangs a left or right hand door - you just flip it. Handing only becomes a factor if you order it electrified, since the wire has to exit on the correct side.

They are not the same mechanism. The TCA2314 uses a concealed anti-friction bearing in a five knuckle barrel and is rated for doors with closing devices. The Hager 1279 is a full mortise plain bearing commercial hinge with five knuckles, rated medium duty, and the Hager 1541 is a stainless plain bearing five knuckle hinge for residential use. Plain bearing hinges carry the load on the knuckle faces rather than a bearing, so match the bearing type to the closer and traffic on the opening before swapping.

The TCA2314 is 4-1/2 inch by 4-1/2 inch and is recommended to hang a door for a 180 degree swing in a standard flush frame. Where the leaf has to throw further out to clear casing or a wall return, the Hager WTBB1168 is a 4-1/2 inch by 6 inch full mortise ball bearing wide throw hinge, heavy weight with five knuckles. The wider leaf requires a matching frame leaf mortise, so confirm the frame prep before ordering.

The TCA2314 is 4-1/2 inch by 4-1/2 inch, so it is a half inch wider across the open leaves than a 4-1/2 by 4 inch hinge and will not sit in that prep without modification. For a 4-1/2 inch by 4 inch replacement, the Don-Jo BB74540 is a full mortise ball bearing hinge in that size, standard duty, in satin chrome - the same 626 satin chrome finish offered on the TCA2314.

Two: 626 satin chrome and BSP black suede powder coat. 626 is the usual match for satin chrome levers, exit devices, and closers on commercial openings, and BSP is the choice when the rest of the opening hardware is black.

Ball, steeple, and hospital tips are available. Hospital tips are the ones to specify in behavioral health, detention, and some healthcare settings, where the sloped tip removes the ligature point at the top of the barrel.

Yes. The Don-Jo BB84545 is a full mortise ball bearing hinge, 4-1/2 inch by 4-1/2 inch, in brass with a satin chrome finish, rated standard duty. The TCA2314 covers the same 4-1/2 inch by 4-1/2 inch opening in stainless steel and is offered in 626 satin chrome as well as BSP black suede powder, so the two can be finish-matched on an opening where base material is the only variable.
