McKinney T4A3795 5 Knuckle Swing Clear Hinge with ElectroLynx Quick Connect Concealed Circuit

The T4A3795 is a swing clear full mortise hinge with a concealed circuit running through the barrel and plug connectors hidden at each leaf. Power comes from the frame side, through the hinge, out to the electrified hardware on the door, so you don't need a separate electric power transfer or an exposed loop. Brass eyelets protect the wire where it passes through. Each circuit carries 4 amps continuous at 24 volts AC or DC on 28 gauge multi-strand wire.

Match the wire count to what the door hardware actually draws. The T4A3795 comes as 4-Wire or 8-Wire with the ElectroLynx connector. Four wires cover a single electrified function, for example an electric strike or an electrified lock with no monitoring. Eight wires give you room for a second function on the same door, such as a lock plus request-to-exit or latch monitoring. Both use an 8 position connector on the hinge end, so the plug interface is the same either way.

Center position. McKinney specifies the electric hinge in the middle of the hinge group, not top or bottom, which keeps the wire run short and puts the transfer point where the frame raceway usually lands. On a three hinge door that is the middle hinge; on a four hinge tall door use one of the two center positions. The other hinges on the opening stay non-electric. Installation instructions ship in the box with each hinge.

The ElectroLynx wiring on this hinge is coordinated to work with other ASSA ABLOY Group brands' electro-mechanical hardware, which is the group Sargent and Corbin Russwin belong to. That means the connector and wire assignments line up and you plug the two together rather than splicing. For hardware outside the ASSA ABLOY group you would need a matching ElectroLynx pigtail or a wire-to-wire connection at the door.

A few directions, depending on what the opening needs. The BEST CECB179-12C is a steel full mortise electrified hinge with a 12-wire quick connect, medium duty, if you need more conductors than eight. Command Access ETH-BB68 is a heavy duty 5 knuckle energy transfer hinge on a steel base and is the closest straight equivalent in weight and knuckle count. ETH-CB70 is the 3 knuckle standard weight option for lighter interior doors. What none of these substitutes is the swing clear geometry: if the reason you are buying the T4A3795 is clear opening width, a conventional electrified butt hinge will not give you that back.

Stanley and McKinney are both ASSA ABLOY lines, but the Stanley CECB1900R54L is a 3 knuckle concealed bearing standard weight hinge at 4-1/2 by 4-1/2 with a 4-wire circuit, and it is handed left. The T4A3795 is a 5 knuckle swing clear hinge, and swing clear leaves have different leaf geometry than a standard butt hinge, so it is not a like-for-like swap into an existing standard prep. Going the other way, if what you have is a standard butt prep and you just need power through it, a 4-wire concealed conductor butt hinge is the closer match.

The T4A3795 is a heavy duty steel 5 knuckle full mortise hinge with the ElectroLynx quick connect concealed circuit, offered with 4-wire and 8-wire ElectroLynx connectors in 4.5 inch and 5 inch sizes, 626 satin chrome. The closest peer for a power transfer opening is the Command Access ETH-BB68 Energy Transfer Hinge, a 5 knuckle heavy duty steel base hinge in the ETH 5 Series. For a standard weight rather than heavy weight leaf, the Stanley Security CECB1900R54L is a three knuckle concealed bearing concealed conductor architectural hinge, steel full mortise, standard weight, 4-1/2 by 4-1/2, square corner, left-handed, 4-wire. Both carry conductors through the hinge the same way the T4A3795 does.

The McKinney T4A3795 is built with 4-wire and 8-wire ElectroLynx connectors. When the opening needs a wider conductor count, the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with 12-wire quick connect, from the Electrified Hinges series at a medium duty rating. That is the one to specify when the electrified lock, monitoring, and request-to-exit circuits all have to share a single hinge.

The T4A3795 carries the ElectroLynx concealed circuit for power transfer. If the opening also needs the door position reported back to the access control panel, the Command Access ETM-BB68 is an energy transfer monitor hinge with an integrated door position switch, heavy duty, in the ETM 5 Series. Its lighter counterpart is the ETM-CB70, an energy transfer monitor hinge with door position sensing on a 3 knuckle steel base at a medium duty rating.

A T4A3795 only earns its place when current has to reach an electric lock or strike on the door leaf. On a non-electrified commercial opening at the same heavy duty level, the Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge, 4-1/2 by 4-1/2, in satin chrome, and the HWBB85045 is the same family at 5 by 4-1/2 in brass with a satin chrome finish. The Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles, also heavy duty.

No. The T4A3795 carries a concealed ElectroLynx circuit that transfers power from the frame through to electrified door hardware without exposed wiring. The Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge, and the Don-Jo HWBB74545 is a heavy weight full mortise ball bearing hinge 4-1/2 by 4-1/2 in satin chrome. Both are mechanical hinges only, with no conductor path, so swapping one in leaves the electrified lock with no power. If the reason for the McKinney was the non-removable pin on an out-swinging door rather than the wiring, the BB1168 covers that.

Two sizes are offered, 4.5 inch and 5 inch, both in 626 Satin Chrome. Pick 4.5 inch for standard 1-3/4 inch commercial doors and 5 inch where the door is heavier or wider and the spec calls for the larger leaf. Both sizes are available with either the 4-wire or the 8-wire ElectroLynx circuit.

McKinney's Magnetic Monitoring (MM) option can be combined with ElectroLynx on most full mortise hinges, so a single hinge can carry both power and a door position signal. One caution from McKinney: the QC12 twelve-wire hinge with MM is not recommended on wood or solid core doors. If you want monitoring built into the hinge as a packaged product instead, the Command Access ETM-BB68 is an energy transfer hinge with an integrated door position switch, and the ETM-CB70 is the 3 knuckle standard weight version of the same idea.

Heavy duty, steel base, five knuckle, square corners, and specified commercial rather than residential. That is the build for exterior entrances, stairwells, and corridor doors that cycle all day. Square corners means it drops into a standard commercial hollow metal frame prep with no radius router work.

Yes, and NRP is available as an option on the T4A3795. On an outswing door the barrel sits on the exterior, so a standard pin can be driven out and the door lifted off. The NRP set screw seats into the pin and blocks that. Order it on any exterior outswing or secure-side opening; for interior inswing doors it is unnecessary.

No handing to specify on this one. McKinney hands its two knuckle hinges; the T4A3795 is a five knuckle hinge, so the same part works on a left hand or right hand door. Note that the electric hinge still goes in the center position regardless of which way the door swings.

One electric hinge per opening is the norm. The T4A3795 carries the power circuit and goes in the center position; the remaining hinges on the door are standard non-electric butt hinges of the same size and finish. For a heavy duty commercial door in 626 Satin Chrome, the Don-Jo HWBB74545 in 4-1/2 by 4-1/2 satin chrome or the HWBB75045 at 5 by 4-1/2 are heavy weight full mortise ball bearing hinges that fill out the rest of the stack. Match the corner style to your frame prep, square in this case.

Each ElectroLynx circuit on the T4A3795 is rated 4 amps continuous at 24 volts AC or DC, which covers typical electrified mortise locks, electric strikes, and electrified trim. Add up the continuous draw of everything on the door and keep it under that per circuit. Magnetic locks generally mount to the frame or header and are fed directly, not through a hinge. The wire itself is 28 gauge multi-strand, so keep runs to the door hardware short rather than extending them.

Both move current through the hinge to electrified hardware. The T4A3795 is a 5 knuckle heavy duty steel hinge with the ElectroLynx quick connect, whose wires are coordinated to work with other ASSA ABLOY Group brands electro-mechanical hardware, and it is sized at 4.5 inch and 5 inch. The Command Access ETH-CB70 is a 3 knuckle standard weight steel base energy transfer hinge in the ETH 3 Series at a medium duty rating. The knuckle count and weight class are the deciding difference on a heavy traffic or heavy leaf opening.

No. The T4A3795 is a commercial heavy duty steel hinge carrying an electrified circuit. Residential hinges such as the Emtek 91013 residential plain bearing hinges in 3-1/2 by 3-1/2 with square corners, the Schlage S3P1010 3.5 by 3.5 square corner plain bearing mortise hinges, or the Ives 1010RP steel plain bearing residential hinges with square corners are plain bearing at a medium duty rating and carry no conductors. They belong on light residential leaves, not on an electrified commercial opening.

The swing clear geometry on the T4A3795 pulls the door leaf clear of the opening so the full clear width is available, which matters for ADA clearance and gurney or cart traffic. On a conventional opening where that is not required, a standard full mortise hinge covers it: the Stanley Security FBB191 is a 5 knuckle full mortise standard weight hinge at 4.5 by 4.5, heavy duty, and the Ives 3CB1 is a steel 3 knuckle concealed bearing full mortise hinge with a medium duty rating. Note that neither carries an electrified circuit, so a separate power transfer device is needed if the door has electrified hardware.

The T4A3795 is a power transfer hinge and does not include a closing spring. When the requirement is self-closing rather than electrified, the Stanley Security 2060R is a spring hinge, full mortise, square corner, 4.5 by 4.5, ferrous steel base, heavy duty. It matches the square corner prep and heavy duty class of the T4A3795 but serves a different purpose entirely.

The T4A3795 is a heavy duty commercial hinge built around the ElectroLynx circuit, not a detention product. For correctional and high abuse openings, the BEST BB855 is a heavy duty steel double weight concealed ball bearing prison hinge in the Detention Hardware series, the Stanley Security BB855 is a double weight prison hinge furnished with no holes and not swaged at 5 by 6, and the Hager 990 STEEL is a full surface prison hinge 3 by 4 with a welded tip, heavy duty. Those are the products written into a detention spec.

The T4A3795 is a full mortise hinge, mortised into both the door and the frame. If the frame cannot be prepped that way, the Hager 1129 is a half mortise plain bearing commercial hinge, 4-1/2, standard weight steel, rated heavy duty, and the Hager 990 STEEL is a full surface prison hinge at 3 by 4 with a welded tip. For a center hung double acting application, the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors.

A common approach is to hold one square corner heavy duty family across the facility and use the electrified version only where the opening needs it. The McKinney T4A3795 covers the electrified square corner openings in 4.5 inch and 5 inch, 626 satin chrome, with an NRP non-removable pin option available. For the mechanical doors, the Don-Jo HWBB84545 heavy weight full mortise ball bearing hinge in 4-1/2 by 4-1/2 satin chrome and the HWBB75045 at 5 by 4-1/2 steel with satin chrome finish keep the same finish and sizes. Where an out-swinging exterior door needs pin security, the Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge.

They are two different words for two different things. Concealed bearing describes where the bearings sit in the knuckle, as on the Ives 3CB1-B, a 3 knuckle concealed bearing full mortise hinge at a medium duty commercial grade, or the Hager 920, a full mortise concealed plain bearing 2 knuckle steel hinge. Concealed circuit, as on the McKinney T4A3795, means concealed plug connectors run current through the hinge to the electrified hardware with no exposed wiring. A hinge can be concealed bearing without carrying any power at all, which is why the two are not interchangeable on an access control opening.

The T4A3795 is prepped for square corners in a heavy duty steel commercial hinge. On lighter interior leaves needing the same square corner prep, the Orca Hardware 3535 Series is a 4-1/2 by 4-1/2 square corner ball bearing commercial hinge at a medium duty rating, and the 4040 Series is a 4 by 4 square corner plain bearing commercial hinge, also medium duty. The Delaney CH401X is a 4 by 4 commercial ball bearing hinge with square corners. If the existing frames are radius corner rather than square, the Orca 4014 Series is a 4 by 4 with 1/4 inch radius corners and the 3514 Series is a 3.5 by 3.5 with 1/4 inch radius.

The McKinney T4A3795 can be ordered with an NRP non-removable pin option, but if the electrified circuit is not needed the pin security is available on mechanical hinges. The Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge, the Deltana CSB45N is a 4-1/2 by 4-1/2 square hinge pair with non-removable pin, and the Deltana DE44R5TA is a 4 by 4 with 5/8 inch radius security hinge with tamper resistant screws in steel, sold as a pair.
