The Command Access Technologies ETH4W5045 626 CH-BB79 Electrified Energy Transfer Hinge provides a concealed low-voltage wiring pathway between the door frame and moving door leaf for compatible electrified commercial door hardware. This 5" high x 4-1/2" wide full-mortise, five-knuckle, standard-weight hinge has the CH-BB79 steel-base configuration and 626 / US26D Satin Chrome finish (supplier finish code 652 / US26D). The wiring is carried through the hinge to eliminate a visible surface-mounted flex loop on appropriately prepared openings.

Correct conductor configuration: This product belongs to the ETH4W family and contains four 26 AWG conductors (4 x 26 gauge). It is not the ETH4WH heavy-wire version, which instead carries two 18 AWG power wires plus two 26 AWG signal wires. Determine whether the lock, reader, trim or monitoring device requires the ETH4W small-gauge bundle or a larger-gauge power-transfer solution before purchasing.

Size and compatibility note: This ETH4W5045 has a hinge size of 5" H x 4-1/2" W, not 4-1/2" x 4-1/2" or 5" x 5". The 5" height requires matching full-mortise door and jamb hinge preparations. Verify screw-hole spacing, hinge thickness, bearing type and corner radius against the Command Access manufacturer's template rather than using a similar-sized hinge as a substitute.

Key Features

• Concealed four-wire electrical transfer: Factory-supplied conductor harness routes compatible low-voltage power and signals discreetly through the door hinge.
• Four 26 AWG conductors: Provides 4 x 26-gauge wires for appropriately rated electric locking hardware, status monitoring and control circuits.
• 5" x 4-1/2" commercial hinge: Fits door/frame openings specifically prepared for the five-inch-tall, four-and-a-half-inch-wide hinge.
• Five-knuckle standard-weight construction: The supplier suffix 5SW identifies the standard-weight, five-knuckle commercial hinge configuration.
• 626 / US26D Satin Chrome: Satin chromium-plated appearance on a steel-base hinge, coordinated with matching commercial door hardware finishes; supplier plating code 652 / US26D.
• CH-BB79 steel-base chassis: Order this specified steel-base version; do not substitute the stainless-steel CH-BB91 series or a different construction without approval.
• Less visible cabling: Integrated power transfer supports a cleaner opening by routing conductors inside the hinge rather than using an exterior exposed cord loop.
• Commercial electrical integration: Appropriate for properly engineered low-voltage door systems when conductor count, current, voltage drop and device compatibility are satisfied.
• Published ETH4W family rating: Manufacturer data identifies 1.0 A continuous at 24 VDC for the designated 26 AWG conductor grouping; confirm limits, conductor assignments, and the current official data sheet for the installed application.
• Wire-access design: Command Access family documentation describes protected, center-located wire access and a non-conductive cap; match the specified door/frame wire preparation.
• Lead configuration: Manufacturer literature provides four-foot lead options; confirm the supplied version's lead length, wiring termination and connector selection before installation.

Product Specifications

Typical Commercial Applications

• Access-controlled door openings using compatible low-current electrified mortise locks or cylindrical locksets
• Approved electrically operated exit trims and other appropriately rated door-mounted accessories
• Door-mounted credential readers, small indicator lamps, or low-voltage sensors, when wired within the hinge rating
• Door-position monitoring and access-control signaling circuits
• Commercial storefront, office, institutional, education, and facility maintenance installations needing concealed frame-to-door wiring
• Replacement of a matching ETH4W5045 626 CH-BB79 unit where the door and frame have the correct hinge and wire access preparation

ETH4W versus ETH4WH

ETH4W5045 uses 4 x 26 AWG conductors. The ETH4WH heavy-wire hinge is a different product containing 2 x 18 AWG power conductors and 2 x 26 AWG signal wires. Some electric latch-retraction equipment, high-inrush solenoids, and powered locking systems require a heavier power pair or another manufacturer-approved transfer method. Do not substitute the ETH4W simply because it is the same size and finish as a heavy-wire hinge.

Installation and Ordering Checklist

1. Verify hinge dimensions: Confirm 5" H x 4-1/2" W and five-knuckle, standard-weight full-mortise preparation.
2. Match the finish and chassis: Specify 626 / US26D Satin Chrome, supplier code 652 / US26D, and CH-BB79 steel-base construction.
3. Check the conductor requirements: Use the four 26 AWG wires within the connected devices' continuous and startup current limitations; account for voltage drop, circuit pairing, wire length, and controller requirements.
4. Confirm the manufacturer hinge template: Match the exact screw locations, hinge corners, door and frame mortises, and approved wire raceway installation to the supplied hinge.
5. Protect the harness: Follow manufacturer instructions for routing and fastening. Avoid conductor damage or pinch points behind the hinge leaves.
6. Test completed opening: Verify continuity, full door swing, electrified locking functionality, signal circuits, required egress operation and rated-door requirements as applicable.
