The SDC PT-5 Concealed Mortise Power Transfer Loop provides a secure and discreet method of routing power or data wiring from the door frame into an electrified door. Its mortised design keeps the transfer loop concealed when the door is closed, helping protect the wiring from tampering, damage, and everyday wear.

The PT-5 is ideal for commercial door openings equipped with electrified locks, electric exit devices, latch-retraction hardware, monitoring switches, and other access-control components. Its flexible steel conduit accommodates field-supplied wiring without restricting the normal movement of the door.
