Sdc PTH-4QDPS 4-conductor Hinge 4.5x4.5 626 Finish

Product Description

The SDC - SECURITY DOOR CONTROLS PTH-4QDPS is a 4-conductor continuous hinge designed to transfer low-voltage power through a door without exposed wiring or surface-mounted conduit. Finished in satin chrome (626), it measures 4.5 x 4.5 inches and is built for access control installations where concealed wiring is required between the door frame and the door leaf. Licensed electricians and access control technicians install this type of device when card readers, electric strikes, magnetic locks, or door position switches must receive power through the hinge point. It ships as a single unit.

This hinge is suited for commercial interior and exterior door applications where low-voltage signal or power conductors need a protected, reliable path across the door pivot axis. Typical use cases include installations with electric hardware on the door leaf — such as electrified exit devices, request-to-exit sensors, or powered locking hardware — where running a wire loop or surface raceway is not acceptable. The 626 satin chrome finish makes it compatible with standard commercial hardware finish schedules.

Key Features

• 4-conductor configuration routes low-voltage power and signal wiring through the hinge barrel
• 4.5 x 4.5 inch hinge leaf size suits standard commercial door applications
• 626 satin chrome finish aligns with common commercial hardware finish schedules
• Conceals wiring at the hinge point, eliminating exposed wire loops on the door edge
• Sold as a single unit, compatible with typical access control electrified door assemblies

Compatibility

Designed as an OEM-style door power transfer hinge for commercial access control door assemblies requiring concealed low-voltage conductor routing through the hinge point.

Installation Notes

Installation is typically performed by a licensed electrician or certified access control technician. De-energize all low-voltage circuits connected to the door hardware before beginning work. Follow applicable NEC guidelines for low-voltage wiring at the door hinge location. Verify conductor gauge and circuit requirements of the connected hardware before terminating leads at the hinge.
