Product Description
The SOSS 218PTUS26D is a heavy-duty invisible power transfer hinge designed to route low-voltage wiring through a door without exposed conduit or surface-mounted cable channels. Finished in satin chrome, this hinge installs flush within the door and frame, keeping the electrical pathway concealed while maintaining a clean architectural appearance. Rated for 1-3/4 inch doors with a leaf size of 1-1/8 inches by 4-5/8 inches, the 218PTUS26D suits applications where card readers, electric strikes, or door position sensors require a continuous power feed to the door itself. It is typically installed by licensed electricians or commercial door hardware specialists.
This power transfer hinge is suited for commercial and institutional door applications where low-voltage wiring must pass between a stationary frame and an active door leaf. Typical installations include access control systems, electric latch retraction hardware, and door monitoring circuits on 1-3/4 inch commercial doors. The concealed design makes it appropriate for high-visibility environments such as offices, hospitals, hotels, and government facilities where surface-mounted cable management is not acceptable.

Compatibility
Designed as an OEM-style replacement or new-installation power transfer hinge for 1-3/4 inch commercial doors requiring concealed low-voltage wiring passage.
Installation Notes
Installation is typically performed by a licensed electrician working in coordination with a commercial door hardware installer. De-energize all low-voltage circuits feeding the door before routing wiring through the hinge transfer channel. Mortise pockets must be precisely routed to the manufacturer’s template dimensions to ensure flush seating and proper door swing clearance. Consult local building codes and NFPA 70 (NEC) requirements for low-voltage wiring methods at door assemblies prior to installation.
