Schlage 5BB1 4.5 X4.5 TW8 652 Electric Thru-wire Hinge

Product Description

The SCHLAGE 5BB1 4.5 X4.5 TW8 652 is an electric thru-wire hinge designed to route low-voltage wiring through a door hinge to power electric hardware such as electric strikes, electromagnetic locks, or access control devices. Measuring 4.5 x 4.5 inches, this hinge allows conductors to pass internally through the knuckle, eliminating exposed wire runs at the door edge. It is installed by licensed electricians or door hardware specialists on commercial door frames requiring integrated wiring access.

This electric thru-wire hinge is suited for commercial hollow metal or wood door applications where access control or electrified door hardware is part of the installation. It is commonly specified in exit device and access control systems where a clean, concealed wire path from frame to door is required. Architects, electrical contractors, and door hardware technicians typically specify this component during new construction or retrofit of commercial entry and egress points.

Key Features

• Internal thru-wire channel routes low-voltage conductors without exposed wiring at the door gap
• 4.5 x 4.5 inch leaf size suits standard commercial door applications
• 652 finish indicates satin chrome, common in commercial hardware specifications
• Sold individually as a single unit
• Designed for integration with electric strikes, electromagnetic locks, and access control hardware

Installation Notes

Installation of electric thru-wire hinges should be performed by a qualified door hardware technician or licensed electrician familiar with access control wiring. Power down all connected electrified hardware before beginning work. Follow applicable NEC guidelines for low-voltage wiring routed through door hardware. Verify wire gauge and conductor count are compatible with the hinge channel capacity before threading conductors.
