Quick Technical Selection Guide
The Command Access 8-Wire Transfer Hinge | 4-1/2 x 4-1/2 is designed to carry compatible low-voltage circuits through the hinge side of an electrified commercial door, keeping the wiring pathway within the prepared door and frame instead of using an exposed surface cord. This model family provides 8 conductors, with selectable factory finishes or preparations shown below. Select by electrical harness, hinge size and mechanical preparation—not by finish alone.
Specification Review: 8-Wire Hinge Installation
Use this 8-conductor electrified transfer hinge as the concealed electrical pathway between a prepared door and frame. Before ordering, match its 4-1/2 x 4-1/2 nominal leaf size, electrical conductor arrangement and architectural finish to the project hardware schedule. Select the factory option matching the specified finish and mechanical preparation.

- ETH8WH4545-652-5SW — 626 Satin Chrome
Installer and Estimator Checklist
- Mechanical preparation: Verify full-mortise hinge template, leaf width, length, thickness, knuckle style, corner radius, screw locations and door/frame reinforcement. Verify load class and any required listing using the exact SKU.
- Electrical routing: Confirm the factory lead and wire gauges, number of circuits, operating current, voltage drop, and available space for field terminations. Route conductors to protect them during full door swing.
- Compatibility: Identify the electric lockset, exit device, transfer switch or door-monitoring accessories connected through the hinge. Match their terminal requirements to the conductor arrangement; do not substitute a standard-weight or mixed-gauge model by wire count alone.
- Testing: Check hinge alignment, free door movement, wire continuity, insulation condition and device operation with the door in open and closed positions.
Package scope: The selected electrified hinge is supplied as its factory assembly. Locks, access controller, external power supply, wiring beyond the supplied leads and installation labor are not included unless separately specified.
Project Specification and Installer Checkpoints
For the 4-1/2 x 4-1/2 8-wire electrified transfer hinge, confirm both the mechanical hinge specification and the electrical circuit layout before selecting a finish. A power-transfer hinge is not interchangeable with a standard butt hinge merely because the leaf dimensions match.
Electrical Design
- Factory conductor configuration: 2 × 20 AWG power conductors + 6 × 28 AWG signal/control conductors. Confirm the wiring arrangement of the exact selected SKU against the current product sheet.
- Connected hardware: Identify the electric lock, latch-retraction hardware, door-position switch or monitoring contacts that the cable serves, and map each conductor to a circuit before installation. Reserve conductor capacity for required power and signals.
- Power sizing: Check total running and inrush current, voltage at the device under load, allowable conductor ampacity and maximum cable length using the electrical device and hinge manufacturers' specifications. Do not assume a particular amperage rating from conductor count alone.
- Termination and movement: Plan protected cable routing through prepared door and frame raceways, proper strain relief and termination access. Verify continuity and insulation integrity with the door fully open and closed.
Mechanical Fit and Ordering Requirements
- Hinge template: Verify leaf height and width, hinge thickness, five-knuckle pattern, screw-hole locations, corner style and door/frame mortise; compare the selected part number to the architectural hardware schedule.
- Door construction: Confirm door weight, hinge quantity, opening frequency, intended fire-door listing and any applicable frame reinforcement or manufacturer restrictions. Do not substitute a different hinge load class solely based on appearance.
- Series distinction: The WH-coded configuration may have a different electrical harness and/or hinge specification from the W-coded family. Check both before substitution.
Commercial Applications and Supplied Scope
For commercial entrance, corridor and other access-controlled openings that require concealed low-voltage transfer from the frame to electrified door hardware. Select the precise factory configuration in the variant menu. This is a power-transfer hinge assembly; the mating lockset, power supply, access controller, door wiring and field installation are separate unless an individual manufacturer package expressly states otherwise.

Choosing the Correct Hinge
- Match the opening: Confirm height, open width, hinge thickness, corner radius, hole pattern and door/frame mortise against the existing hinge or new construction schedule.
- Size the circuit: Calculate the connected lock/trim device's operating and inrush current, voltage drop, required conductors and control contacts. Use the current Command Access electrical ratings for the selected SKU.
- Check the power transfer: Route the factory wiring through the designated hinge and approved door/frame raceways without pinching or stressing the leads through the full swing cycle.
- Coordinate door hardware: Verify electric locks, readers, monitor switches, exit trim, power supply and access controller are electrically compatible before installation.
- Inspect and test: Verify conductor continuity, insulation, mechanical door movement and powered hardware operation after installation. Follow applicable fire-door and egress requirements.
Important model distinction: ETH8WH provides a distinct power pair from ETH8W, which uses eight 28 AWG conductors; verify load and voltage-drop requirements.
