The ETH-BB79 Energy Transfer Hinge is a robust and secure solution for routing low-voltage power from the frame to door-mounted hardware without any exposed or vulnerable wiring. Designed for heavy-use commercial environments, the ETH hinge ensures clean, discreet, and durable wire transfer, maintaining the aesthetic of a conventional hinge while adding vital electronic capability.

Whether you're integrating with electrified exit devices like the MLRK1-VD for Von Duprin 33/35 or 98/99 series, or installing electric mortise/cylindrical locks, electric strikes, exit trims, door lights, or card readers, the ETH-BB79 delivers seamless power continuity.

• Works perfectly with:

  • Motorized Latch Retraction Kits like MLRK1-VD

  • Electrified mortise & cylindrical locks

  • Electric exit trims & pullback exit devices

  • Door-mounted card readers & low-voltage indicators

• Ideal for:

  • New construction or retrofit on hollow metal and wood doors

  • High-security or access-controlled openings

• Material: Steel base, 5-knuckle design

• Power Transfer: Internal wire routing eliminates exposed conductors

• Concealment: All wiring is protected and invisible when the door is closed

• Voltage Use: Supports low-voltage applications (commonly 12VDC to 24VDC systems)

• Mounting: Installs like a conventional hinge no specialized prep required

• Customization: Available in most major hinge brands, finishes, and sizes

Use the ETH-BB79 with systems like Command Access MLRK1-VD to maintain clean installations and protect all electrified connections from tampering or wear. This hinge is an essential component for ADA-compliant, access-controlled, and code-compliant door openings.
