McKinney TA314 4-1/2" x 4-1/2" 32D Full Mortise Hinge

Product Description

The McKinney TA314 4-1/2" x 4-1/2" 32D is a commercial-grade, standard-weight full mortise 3-knuckle hinge designed for standard-frequency interior and exterior doors in institutional, commercial, and high-end residential settings. Engineered for smooth operational life, this hinge features precision stainless steel ball bearings and a non-rising removable pin.

Crafted from solid stainless steel with a 32D Satin Stainless Steel finish (US32D), the TA314 offers maximum corrosion resistance, making it an excellent choice for coastal environments, hospitals, laboratories, and high-moisture applications. Its clean, square-corner profile provides a sleek, modern aesthetic while adhering to standard architectural prep specifications.

Product Features

  • Standard-Weight 3-Knuckle Design: Engineered with a streamlined 3-knuckle profile that offers clean architectural sightlines while maintaining heavy-duty performance.

  • 32D Satin Stainless Steel Finish (US32D): Made from solid stainless steel base material for maximum corrosion resistance and durability in harsh or humid environments.

  • Precision Ball Bearings: Equipped with engineered ball bearings to ensure smooth, quiet door swing and reduce wear over long-term operation.

  • Non-Rising Pin: Includes a non-rising removable steel pin that prevents the hinge pin from working itself upward during continuous door usage.

  • Square Corner Prep: Standard 90° square corners fit standard architectural hollow metal and wood door mortise prep cutouts.

McKinney TA386 4-1/2 X 4 630 – Frequently Asked Questions

1) Will the McKinney TA314 hinge drop into an existing 4-1/2 x 4-1/2 square corner door and frame prep?
Yes. The TA314 is a 4-1/2 x 4-1/2 inch (114mm x 114mm) full mortise hinge with 90 degree square corners, cut to standard architectural hollow metal and wood door mortise prep. If your existing hinge pockets are square cut at 4-1/2 inches, it goes straight in. Radius corner pockets are a different prep and will leave a gap at the corners.
2) Is a standard weight hinge like the TA314 enough for a door with a closer on it?
Yes, within its rating. McKinney lists the TA314 for standard weight, medium frequency doors, including doors with closing devices. It runs 0.134 inch (3.4mm) leaf thickness with stainless ball bearings to take the extra load a closer puts on the top hinge. For a heavy or continuously cycled opening, step up to a heavy weight concealed bearing hinge such as the Ives 3CB1HW.
3) What is the NRP option on the McKinney TA314 and when do I need it?
NRP is the non-removable pin option. It adds a set screw that locks the pin in place once the door is closed, so the hinge cannot be knocked apart from the pull side. Specify it on any out-swinging exterior or secure door where the barrel is exposed. On in-swinging interior doors the standard non-rising removable pin is fine and easier to service.
4) Will a stainless steel hinge hold up on exterior doors near the coast or in a wash-down area?
That is what the TA314 is built for. The leaves and pin tips are solid stainless steel in a 32D (US32D) satin stainless finish, which resists corrosion far better than a plated steel hinge. McKinney calls out coastal sites, hospitals, labs and high-moisture applications. Most of the alternatives in the same size, such as the Stanley FBB191 and the Ives 3CB1, are ferrous or plated steel bases and are better suited to dry interior openings.
5) What should I use instead of the McKinney TA314 if I need to run wire through the hinge for an electrified lock?
The TA314 is a mechanical hinge with a removable pin and no conductor path. For power transfer through the door edge, the Command Access ETH-CB70 is a 3-knuckle standard weight steel energy transfer hinge, and the Stanley CECB1900R54L is a 3-knuckle concealed bearing concealed conductor hinge in steel full mortise, standard weight, 4-1/2 inch by 4-1/2 inch square corner, left-handed with 4 wires. If you also need door position monitoring, the Command Access ETM-CB70 combines energy transfer with door position sensing on a 3-knuckle steel base.
6) What is a same-size equivalent to the McKinney TA314 4-1/2 inch square corner ball bearing hinge from another brand?
The Orca Hardware 3535 Series is a 4-1/2 inch x 4-1/2 inch square corner ball bearing commercial hinge, matching the TA314 on size, corner style, and bearing type. The Orca is rated medium duty, while the McKinney TA314 is a stainless steel, heavy duty commercial hinge. Another close size match is the Stanley Security FBB191 full mortise standard weight hinge at 4.5 inch x 4.5 inch, though it uses a 5-knuckle barrel rather than the TA314's 3 knuckles.
7) Is a concealed bearing hinge like the Ives 3CB1 the same thing as the McKinney TA314?
No. Both are 3-knuckle full mortise hinges, but the Ives 3CB1 uses a concealed bearing and is rated medium duty, while the McKinney TA314 carries visible ball bearings between knuckles and is a heavy duty stainless steel hinge. If you need heavier capacity with the concealed bearing look, the Ives 3CB1HW is a 3-knuckle steel heavy weight concealed bearing full mortise hinge.
8) I need the non-removable pin version of a 4-1/2 inch commercial hinge for an outswing exterior door - what are my options besides the McKinney TA314?
The TA314 can be ordered with the NRP non-removable pin option. If you want a factory NRP hinge from another line, the Hager BB1168-NRP is a full mortise ball bearing heavy duty hinge supplied with a non-removable pin. For a residential-scale outswing door, the Deltana CSB45N is a 4-1/2 inch x 4-1/2 inch square hinge sold in pairs with a non-removable pin.
9) What looks like a substitute for the McKinney TA314 but will not fit a full mortise frame prep?
Several hinges share the commercial look but use different mounting. The Hager 1129 is a half mortise plain bearing hinge, which mortises into the door but surface-mounts to the frame. The Hager 990 is a full surface prison hinge at 3 inch x 4 inch with a welded tip. The BEST DAP-3 is a double acting pivot rather than a butt hinge. The TA314 is a full mortise hinge that drops into standard square corner mortise pockets in both the door and the frame.
10) Do I need to order screws separately for the McKinney TA314?
No, fasteners come in the box. Each hinge is packed with a full set of machine screws (1/2 in x #12-24) for hollow metal frames and wood screws (1-1/4 in x #12) for wood doors, drilled to 4-1/2 inch template. You use one set or the other depending on whether you are into metal or wood.
11) Does the TA314 hinge need to be ordered left or right handed?
No handing to specify. It is a 3-knuckle full mortise bearing hinge with a non-rising removable pin, symmetrical and non-handed, so the same hinge works on a left or right hand door. Compare that with an electrified hinge like the Stanley CECB1900R54L, which is handed because of the wire exit.
12) Can I hang a door for a full 180 degree swing on these hinges?
Yes. McKinney recommends the TA314 for hanging a door with a 180 degree swing, so the leaves clear the frame face when the door is thrown fully open. You still need the wall or adjacent trim to be out of the way for the door to actually reach 180.
13) What ANSI standard does the McKinney TA314 hinge meet?
It complies with ANSI/BHMA A156.1 and is certified A5112. That is the number an institutional spec writer or facility procurement group will want on the submittal for a commercial hinge.
14) What is the difference between a 3-knuckle bearing hinge like the TA314 and a 5-knuckle hinge?
Both carry the door, but the sightline differs. The TA314 uses a 3-knuckle barrel, which gives a cleaner architectural look and fewer joints. A 5-knuckle standard weight hinge such as the Stanley FBB191 in the same 4-1/2 x 4-1/2 size spreads the load over more bearing points and is the more common commercial default, so it is often the one already on the door if you are matching existing openings.
15) Is there a simpler or lighter hinge than the McKinney TA314 for low-traffic interior doors?
The TA314 is recommended for standard weight, medium frequency doors or doors with closing devices. For lighter interior openings, the Orca Hardware 4040 Series is a 4 inch x 4 inch square corner plain bearing commercial hinge rated medium duty, and the Ives 1010RP is a steel plain bearing residential hinge with square corners sold in sets of three. Plain bearing hinges have no ball bearings between the knuckles, so they are intended for lower cycle counts than a bearing hinge.
16) Can a spring hinge replace the McKinney TA314 if I need the door to self-close?
Not directly on function. The TA314 is a free-swinging bearing hinge and is recommended for doors with separate closing devices. The Stanley Security 2060R is a full mortise spring hinge in 4.5 inch x 4.5 inch square corner with a ferrous steel base, so it matches the TA314's size and corner prep while providing the closing force itself. Confirm your local code accepts spring hinges as the closer on that opening.
17) For a detention or high-abuse opening, is the McKinney TA314 enough or should I step up?
The TA314 is a standard weight stainless steel hinge suited to standard frequency interior and exterior doors in institutional and commercial settings. For detention-grade openings, the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge, and the Stanley BB855 is a double weight prison hinge furnished with no holes and not swaged at 5 inch by 6 inch. The BEST CB1969R is a concealed bearing heavy weight pivot-reinforced hinge for heavy doors that need frame reinforcement.
18) Are the 3-1/2 inch residential hinges from Emtek or Deltana interchangeable with the McKinney TA314?
No. The TA314 is 4-1/2 inch x 4-1/2 inch, so it will not drop into a 3-1/2 inch mortise pocket. The Emtek 91013 is a residential plain bearing hinge pair at 3-1/2 inch x 3-1/2 inch with square corners in plated steel, and the Deltana DSB35 is a 3-1/2 inch x 3-1/2 inch residential square hinge pair. If you want a bearing hinge at that smaller size, the Emtek 94013 is a heavy duty ball bearing pair at 3-1/2 inch x 3-1/2 inch with square corners.
19) Is there a 4 inch ball bearing commercial hinge comparable to the McKinney TA314 for a smaller door?
Yes. The Delaney CH401X is a 4 inch x 4 inch commercial ball bearing hinge with square corners, so it shares the TA314's bearing type and square corner prep at the smaller leaf size. The McKinney TA314 is 4-1/2 inch x 4-1/2 inch in stainless steel, which is the larger leaf typically specified on heavier commercial doors.
20) What finish and size does the McKinney TA314 come in?
One combination: 4-1/2 x 4-1/2 inch in 630 satin stainless steel, which is the same as US32D / 32D. If you are standardizing a building on 630, this matches stainless levers, closers and push plates in the same finish code.
21) Is there a non-bearing alternative if I do not need ball bearings at 4-1/2 inches?
Yes, but be careful about the load. A plain bearing hinge like the Hager 1129 is a 4-1/2 inch standard weight steel hinge, though it is a half mortise, not a full mortise, so the prep is different. The TA314's stainless ball bearings are what let it carry a door with a closer without dragging, so on any closer-equipped opening stay with a bearing hinge.
