The SDC PT-3V Power Transfer Door Loop provides a simple and economical way to route electrical power or data wiring from the door frame to electrified hardware installed in the door. Its surface-mounted design allows for straightforward installation without requiring a concealed mortise power-transfer device.

The PT-3V features durable stainless-steel armored flex conduit with aluminum termination boxes. It is recommended for hollow-metal and aluminum-frame door applications equipped with electric locks, electrified exit devices, monitoring switches, or other access-control hardware.

Installation Note

The PT-3V is a surface-mounted power-transfer loop, not a concealed power transfer. The aluminum termination boxes mount to the door and frame, while the flexible armored conduit protects the wiring as the door opens and closes. Confirm the mounting location, door swing, required wire capacity, and clearance from hinges or pivots before installation. SDC lists the PT-3V for openings up to 180 degrees.
