The Command Access Technologies ETH4W4545 626 CH-BB68 Electrified Energy Transfer Hinge provides concealed low-voltage power and signal transfer between a commercial door frame and the moving door leaf. The 4-1/2" x 4-1/2" commercial hinge has a five-knuckle, heavy-weight (5HW), full-mortise construction and a 626 / US26D Satin Chrome finish on the specified CH-BB68 steel-base chassis. Its factory-installed conductors route wiring through the hinge without a visible external cable loop on a properly prepared commercial opening.

Important mechanical/electrical distinction: 5HW means a heavy-weight hinge with heavier-duty mechanical construction than the standard-weight 5SW CH-BB79 version. The ETH4W electrical harness still uses four 26 AWG wires (4 x 26 gauge conductors). This is NOT the ETH4WH heavy-wire model containing two 18 AWG power wires plus two 26 AWG signal wires. Hinge weight class and conductor wire gauge are separate specifications.

Exact finish and ordering specification: Specify the ETH4W4545-652-5HW, manufacturer model ETH4W4545 626 CH-BB68, for a 4-1/2" high x 4-1/2" wide, square-corner, five-knuckle heavy-weight hinge in 626 / US26D Satin Chrome. Supplier plating code 652 / US26D indicates satin chromium plating on the steel base. This item is different from ETH4W4545 626 CH-BB79, which is the 5SW standard-weight hinge. Check the hinge gauge, bearing type, mounting-hole template, door weight and usage requirements before substituting one configuration for another.

Understand 5HW, 5SW and ETH4WH

5HW designates five-knuckle heavy-weight hinge construction. The 5SW designation is a five-knuckle standard-weight hinge, which may require a different hinge preparation or carrying capacity. ETH4W specifies an electrical bundle of 4 x 26 AWG wires. ETH4WH is a separate heavy-wire electrical configuration with a 2 x 18 AWG power pair plus 2 x 26 AWG control wires. Do not assume that a heavy-weight hinge provides heavier electrical conductors or satisfies electric latch-retraction power demands. Evaluate continuous and inrush current, voltage, duty cycle, conductor grouping and voltage drop.

Ordering and Installation Checklist

1. Verify the opening: Confirm 4-1/2" high x 4-1/2" wide full-mortise leaf size, door/frame material and approved square-corner hinge preparation.
2. Check mechanical requirements: Select 5HW heavy-weight CH-BB68, not 5SW CH-BB79. Match the current manufacturer's hinge thickness, bearing, number of hinges, screw-hole layout and template.
3. Confirm finish: Specify 626 / US26D Satin Chrome with supplier code 652 / US26D; do not substitute bright chrome, stainless steel or other finishes.
4. Check wire requirements: This product contains four 26 AWG wires and does not include an 18 AWG power pair. Match electrical design, load, conductor grouping and manufacturer instructions.
5. Prepare protected wiring: Route conductors through the jamb and door raceways using the factory cut sheet; prevent conductor abrasion, pinching, sharp bends and over-tension.
6. Verify code compliance: Coordinate fire-rated doors, access-control locking and exit/egress functions with the approved opening design and local code requirements.
7. Test after installation: Verify wire continuity, door swing, latching, powered hardware operation and status circuits.

The Command Access Technologies ETH4W4545 612 CH-BB68 Electrified Energy Transfer Hinge provides a concealed electrical pathway between the hinge jamb and door leaf for compatible low-voltage commercial access-control hardware. This model is a 4-1/2" high x 4-1/2" wide, five-knuckle heavy-weight (5HW) full-mortise hinge with a 612 / US10 Satin Bronze plated, clear-coated finish on a CH-BB68 steel-base chassis. Its factory-installed wiring allows approved power, monitoring and control signals to pass through the door hinge without a visible exterior flex loop when installed with correctly prepared door and frame raceways.

Correct product and finish: Supplier part number ETH4W4545-639-5HW matches manufacturer model ETH4W4545 612 CH-BB68. The 639 / US10 supplier finish code denotes satin bronze plated and clear coated, which is different from the darker 613 / US10B Oil Rubbed Bronze, 626 satin chrome and 630 satin stainless finishes. Check the architectural finish and manufacturer hinge template against the project's approved door-hardware schedule before replacing an existing hinge.

Important hinge weight vs. wire gauge distinction: 5HW identifies the heavy-weight mechanical hinge construction; it does not indicate a larger wire harness. The ETH4W electrical configuration uses four 26 AWG conductors (4 x 26 gauge). The separate ETH4WH heavy-wire series uses two 18 AWG power wires and two 26 AWG signal wires. Confirm continuous current, startup current, voltage drop, cable length and wiring assignments for the connected electric lock, exit trim, motor, sensor or reader before purchase.

Key Features and Benefits

• Heavy-weight five-knuckle hinge: The 5HW designation identifies the heavy-weight commercial mechanical construction. It is distinct from a standard-weight 5SW CH-BB79 hinge.
• 4-1/2" x 4-1/2" full-mortise size: Fits door and frame hinge preparations made for the correct four-and-a-half-inch height and width. Verify hole spacing, corner style and hinge gauge before installation.
• Four-wire concealed transfer: Integrates 4 x 26 AWG factory wiring to carry compatible low-voltage electrical circuits from the stationary frame into the door leaf.
• 612 / US10 Satin Bronze: Attractive satin bronze plated finish with a clear protective coating, suitable for coordinating with other 612 architectural commercial door hardware.
• 639 / US10 distributor finish code: Supplier part number ends in 639-5HW to distinguish this exact 612 satin bronze heavy-weight version from 640 oil-rubbed bronze.
• CH-BB68 steel-base chassis: Exact heavy-weight hinge configuration; do not substitute a CH-BB79 standard-weight hinge or CH-BB91 stainless-base version without checking requirements.
• Square-corner mortise preparation: Confirm the manufacturer's current template, screw-hole positions, leaf thickness, bearing arrangement and frame-to-door wire raceways for the actual opening.
• Clean architectural appearance: Internal conductor routing avoids a visible loop at the hinge side of the door when wiring is protected and installed per factory instructions.
• Access-control integration: Suitable for compatible low-current electrified mortise and cylindrical locksets, electric exit trims, status monitoring circuits and door-mounted accessories, subject to manufacturer limits.
• ETH4W electrical rating: Published manufacturer family data identifies 1.0 amp continuous at 24 VDC for the designated wire arrangement; check current applicable specifications and the attached hardware's actual electrical load.
• Protected wire access: Command Access ETH literature describes a center-located wire-access feature and non-conductive protective cap to help preserve the harness.
• Lead options: The ETH family literature describes four-foot wiring leads. Confirm the length, connectors, terminations and supplied fasteners for the ordered SKU.
• Commercial installation support: Follow current Command Access cut sheets and local requirements for hardware safety, rated door openings and emergency egress.

ETH4W, ETH4WH, 5HW and 5SW Explained

ETH4W describes the four 26 AWG electrical conductors supplied in this hinge. ETH4WH is a different wiring harness with a larger power pair and must be chosen when specifically required by the electrical system. The separate designation 5HW means five-knuckle heavy-weight mechanical construction, whereas 5SW identifies a standard-weight hinge. A heavy-weight hinge does not necessarily support high current, heavy electric latch retraction, or higher power transfer. Calculate all applicable electrical loads and inspect the manufacturer's detailed cut sheet before selecting.

Ordering and Installation Checklist

1. Verify exact hinge size: Confirm 4-1/2" height, 4-1/2" width and full-mortise preparation; a 4-1/2" x 5" or 5" x 4-1/2" hinge is not interchangeable.
2. Confirm hinge construction: Match 5HW heavy-weight, CH-BB68 rather than 5SW CH-BB79. Check current factory leaf thickness, mounting holes, bearing, fasteners and door load.
3. Match finish: Select 612 / US10 Satin Bronze with 639 / US10 supplier code, not 613 oil-rubbed bronze or 626 satin chrome.
4. Review electrical load: Use four 26 AWG conductors only with appropriately rated power/signal circuits; account for voltage drop, startup current and wire grouping.
5. Prepare wiring raceways: Follow manufacturer instructions for internal hinge-side door and jamb wiring. Prevent pinching, chafing, cuts or sharp bends.
6. Confirm code and compatibility: Check fire-door approval, door/frame configuration, access-control design and applicable egress requirements for the full opening.
7. Test final installation: Verify hinge clearance, full door swing, wire continuity, electric locking and status circuits before putting the door in service.
