The SDC PT-2U Power Transfer Door Loop, commonly referenced as the SDC PT-2, provides a simple and economical method of routing electrical power or data wiring from the door frame to electrified hardware installed in the door.

The surface-mounted design allows for easy installation without mortising the door or frame. Its stainless-steel armored flexible conduit protects field-supplied wiring while allowing the door to open and close normally. Plastic end caps provide finished mounting points at the door and frame.

Features

• Surface-mounted power transfer door loop
• Transfers power or data wiring between the frame and door

Common Applications

The SDC PT-2U can be used to route wiring for:

• Electrified cylindrical and mortise locks

Installation Note

The PT-2U is a surface-mounted power transfer loop, not a concealed power-transfer device. One plastic end cap mounts to the frame and the other mounts to the door, allowing the armored conduit to flex as the door operates. Confirm the mounting position, door swing, wire quantity, wire diameter, and required clearance before installation.
