Built on a steel base and finished in US26 Bright Chrome, this hinge transfers low-voltage wiring through the door frame to power electric locks, electromagnetic holders, or other door-mounted electrified hardware. At 4.5 inches x 4.5 inches, it fits standard full-mortise hinge preps on commercial-grade hollow metal and wood doors. Installation is performed by licensed locksmiths, access control technicians, or commercial door hardware specialists working within electrified openings.\u003c\/p\u003e\n\u003cp\u003eThis hinge is suited for commercial interior and exterior door openings where concealed wiring transfer is required between the frame side and the door-mounted device. It eliminates the need for exposed conduit or surface-mounted wire runs at the door edge, making it appropriate for retrofit and new-construction access control projects. The 4-wire configuration supports common access control functions including power, ground, and signal leads for electric latch retraction or monitoring circuits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-wire configuration supports power and signal transfer through the hinge knuckle\u003c\/li\u003e\n  \u003cli\u003e4.5 inches x 4.5 inches leaf size fits standard full-mortise hinge preparations\u003c\/li\u003e\n  \u003cli\u003eSteel base construction provides structural durability at high-cycle openings\u003c\/li\u003e\n  \u003cli\u003eUS26 Bright Chrome finish matches commercial hardware finish schedules\u003c\/li\u003e\n  \u003cli\u003eEliminates exposed wiring at door edges for a clean, code-compatible installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style electric transfer hinge replacement for commercial doors requiring a 4.5 inches x 4.5 inches full-mortise hinge with 4-wire low-voltage pass-through capability.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed access control technician or commercial door hardware installer familiar with low-voltage wiring practices.
