McKinney TA2314 Square Corner 5 Knuckle Full Mortise Hinge with ElectroLynx Quick Connect Concealed Circuit

Power runs through concealed plug connectors built into the hinge, so current passes from the frame side through to the electrified hardware on the door with no separate power transfer device and no visible loop cord. Brass eyelets protect the wire where it passes through the knuckle. Circuits carry 4 amps continuous at 24 volts AC or DC using 28 gauge multi-strand wire, which covers typical electric strikes, electrified levers and mag-latch retraction loads at 24V.

Center position. McKinney specifies the electrified hinge go in the middle of the hinge set, with standard non-electrified hinges top and bottom, so the wire run and the connector are not fighting the door closer at the top or picking up floor debris at the bottom. Installation instructions ship in the box with each hinge.

Count the circuits your door hardware needs. The TA2314 comes as a 4-wire, 8-wire or 12-wire concealed circuit hinge, all in 4-1/2 x 4-1/2 inch. Four wires handle a single function such as an electrified lever or a latch retraction feed. Eight covers two functions, for example power plus a request-to-exit or latchbolt monitor switch. Twelve is for openings stacking power with several monitoring signals. QC4 and QC8 use an 8 position connector; QC12 uses an 8 position plus a 4 position connector, so a 12-wire hinge lands two plugs in the frame pocket.

It is a standard duty, standard weight hinge, and McKinney recommends it for standard weight, medium frequency doors or doors with closing devices. So a door with a closer is within its intended use, but a high traffic entrance or a heavy door wants a heavy weight hinge instead. Ball bearings carry the load in the knuckles.

Yes if the existing hinge pocket is square cut, which is what nearly all hollow metal frames and doors are prepped for. The TA2314 has square corners, so it will not sit right in a wood door mortised with a radius corner router (1/4 inch or 5/8 inch radius) without recutting the corners. Check the corner of the pocket you are replacing out of before ordering.

The Command Access ETM-BB68 energy transfer monitor hinge has an integrated door position switch and is a heavy duty ETM 5 Series unit; the ETM-CB70 does the same job with door position sensing on a 3 knuckle medium duty steel base. The McKinney TA2314 is a power transfer hinge whose ElectroLynx circuit can be used together with the Magnetic Monitoring (MM) option on most full mortise hinges, though QC12 with MM is not recommended for wood or solid core doors. If the door is wood or solid core and you want 12 wires plus monitoring, the ETM hinges put the switch in one part instead.

Not for the electrified leaf. The Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge in 4-1/2 inch by 4-1/2 inch satin chrome, and the Orca 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge at a medium duty rating. Both match the TA2314's 4-1/2 by 4-1/2 footprint and ball bearing construction, so they are correct choices for the top and bottom positions on the same door. Neither carries a concealed conductor, and the TA2314 with ElectroLynx is what transfers power to the electrified hardware from the center position where the electric hinge is installed.

The closest peer is the Stanley Security CECB1900R hinge, a steel full mortise standard weight concealed bearing concealed conductor architectural hinge in 4-1/2 inch by 4-1/2 inch with square corners and 4 wires. It lines up with the TA2314 on the points that matter for an electrified opening: same 4-1/2 by 4-1/2 size, same square corner prep, same standard weight class, and a concealed conductor running power through the hinge. The TA2314 is a 5 knuckle ball bearing hinge, while the Stanley is a three knuckle concealed bearing hinge, so knuckle count and bearing style differ. One ordering note: the Stanley unit named here is left handed, where the TA2314 in 4 wire, 8 wire, and 12 wire ElectroLynx builds is not called out as handed.

The BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect at a medium duty rating. Against the TA2314 QC12, the differences are construction: the TA2314 is a 5 knuckle ball bearing standard duty hinge with square corners, where the BEST unit is a concealed bearing design. On the McKinney side, the 12 wire hinge uses an 8 position and a 4 position connector, while the QC4 and QC8 builds use a single 8 position connector, and all circuits are rated for 4 amp continuous at 24 volts AC or DC with 28 gauge multi-strand wires.

Both are supplied: 1/2 inch #12-24 machine screws for tapped hollow metal frames and doors, and 1-1/4 inch #12 wood screws for wood doors and frames. No separate fastener pack to order.

The ElectroLynx wiring is coordinated to work with electro-mechanical hardware from other ASSA ABLOY Group brands, so the plug connectors mate rather than requiring you to cut and splice at the door edge. Pairing it with hardware outside that group means checking that the other end accepts an ElectroLynx connector or planning for a transition harness.

No. Handing applies to two knuckle hinges; the TA2314 is a 5 knuckle full mortise hinge, so one part covers left and right hand openings. Worth knowing when you are buying electrified hinges for a building with doors swinging both ways, because some competing concealed conductor hinges are handed. The Stanley CECB1900R54L, for example, is a left handed 4-wire hinge.

Yes, NRP is available as an ordering option on the TA2314. On an outswing door the barrel is on the secure side of the opening, so a removable pin lets someone drop the pin and lift the door; NRP puts a set screw in the barrel that seats against the pin once the door is closed. Specify it at the time of order, not after.

The TA2314 is built for standard weight, medium frequency doors or doors with closing devices, so a detention opening calls for something else. The BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge from the Detention Hardware series, the Stanley Security 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 heavy duty full surface prison hinge at 3 inch by 4 inch with a welded tip. None of these carry a power transfer circuit, so an opening that needs both current and detention grade construction has to route power another way.

If nothing on the door needs power, the Stanley Security FBB191 is a 5-knuckle full mortise standard weight hinge in 4.5 inch by 4.5 inch, which matches the TA2314's 5 knuckle count and 4-1/2 by 4-1/2 size without a conductor. The Orca 3535 Series 4-1/2 by 4-1/2 square corner ball bearing commercial hinge also matches the TA2314's square corner prep and ball bearing construction. Either drops into the same mortise, so the frame and door prep does not change.

They share the non-removable pin idea and the 4-1/2 inch by 4-1/2 inch square size, but they are different products. The Deltana CSB45N is a 4-1/2 by 4-1/2 square hinge sold as a pair with a non-removable pin, in the DSB45 Series. The TA2314 is a commercial steel 5 knuckle ball bearing full mortise hinge with an ElectroLynx concealed circuit, and NRP is a selectable option on it. For an out-swinging exterior door with electrified hardware, the TA2314 with NRP keeps both the security pin and the power transfer in one hinge.

Several square corner hinges share the look but not the application. The Ives 1010RP is a steel plain bearing residential hinge with square corners sold in sets of three, the Schlage S3P1010 is a 3.5 by 3.5 square corner plain bearing mortise hinge in packs of three, and the Emtek 91013 is a residential plain bearing hinge pair at 3-1/2 by 3-1/2 with square corners. All three are plain bearing rather than ball bearing, all are residential in intent, and the 3-1/2 inch sizes will not fill a 4-1/2 inch mortise. The TA2314 is a commercial ball bearing hinge in 4-1/2 by 4-1/2 carrying an ElectroLynx circuit, so none of these substitute for it.

They do the same job with different construction. The ETH-CB70 is a 3 knuckle standard weight steel base energy transfer hinge in the ETH 3 Series at a medium duty rating; the TA2314 is a 5 knuckle standard duty ball bearing full mortise hinge with square corners. Both pass current through the hinge to electrified hardware. Confirm the existing frame prep and hinge size before swapping, and note that the McKinney wiring is coordinated to work with other ASSA ABLOY Group brands electro-mechanical hardware, which matters if the lock or exit device on the opening is from that group.

The TA2314 is a full mortise hinge, so it needs mortised prep in both the door and the frame. Where the frame cannot be mortised, the Hager 1129 is a half mortise plain bearing commercial hinge in 4-1/2 inch standard weight steel, and the Hager 990 STEEL is a full surface hinge at 3 inch by 4 inch. For a center hung swinging door, the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors. These change how the door is hung rather than matching the TA2314's prep, and none carries a concealed circuit.

Only where the opening does not need power through the hinge. The Hager BB1168 is a non-removable pin full mortise ball bearing hinge at a heavy duty rating, matching the TA2314 on full mortise prep and ball bearing construction and giving the same security pin the TA2314's NRP option provides. The TA2314 is standard duty and carries the ElectroLynx concealed circuit, which the Hager does not. On a door where the electric hinge sits in the center position, the BB1168 can take the top and bottom leaves.

The TA2314 does not; it is recommended for standard weight, medium frequency doors or doors with closing devices, meaning a separate closer handles the closing. The Stanley Security 2060R is a full mortise spring hinge with square corners in 4.5 inch by 4.5 inch on a ferrous steel base at a heavy duty rating, which puts the closing force in the hinge itself. It shares the TA2314's 4-1/2 by 4-1/2 size and square corner prep, so it fits the same mortise, but it carries no power transfer circuit.

No, the sizes do not match. The Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners and the Orca 4040 Series is a 4 inch by 4 inch square corner plain bearing commercial hinge at a medium duty rating, while the TA2314 is supplied in 4-1/2 inch by 4-1/2 inch. A 4 inch leaf leaves a gap in a 4-1/2 inch mortise and the screw pattern will not line up. Measure the existing cutout before ordering; if it is 4 inches, those hinges fit the prep, and if it is 4-1/2 inches, the TA2314 is the size that matches.

Two finishes are offered on the TA2314: 626 satin chrome and 630 satin stainless steel, both in 4-1/2 x 4-1/2 inch and available across the 4, 8 and 12 wire options. 626 matches the satin chrome used on most commercial lever and exit hardware. 630 is the usual pick on stainless door and frame packages and in coastal or wash-down environments. The hinge base is steel in either case.

McKinney lists the TA2314 as recommended to hang a door for a 180 degree swing. Full swing still depends on what is in the way at the opening, trim, a wall stop, or a door closer arm, but the hinge itself is not the limiting factor.

The TA2314 is a 5 knuckle ball bearing full mortise hinge in commercial steel with square corners. The Ives 3CB1 is a 3-knuckle concealed bearing full mortise hinge at a medium duty rating, and the 3CB1HW is the heavy weight steel version of that same concealed bearing 3 knuckle design. The visible difference is the barrel: five knuckles with exposed ball bearings versus three knuckles with the bearings hidden inside. If the rest of the doors in the building already run 3 knuckle concealed bearing hinges, the Ives units keep the sightline consistent, while the TA2314 is what brings a power circuit to the opening that needs one.
