Sdc PTH-2+4Q Electric Hinge 4.5 Inch 2+4 Wire

Product Description

The SDC - SECURITY DOOR CONTROLS PTH-2+4Q is a 4.5-inch electric hinge designed to carry low-voltage wiring through a door hinge without exposed wiring runs along the door frame or jamb. It provides a concealed pathway for electrical conductors, supporting both 2-wire and 4-wire configurations in a single unit. This type of hinge is used in access control, electrified lockset, and door monitoring applications where a clean, code-compliant wire transition from the frame to the door leaf is required. Installation is typically performed by a licensed electrician or access control technician working alongside a door hardware specialist.

The PTH-2+4Q is suited for commercial and institutional door openings where electrified hardware must be powered or monitored at the door leaf. Typical applications include electric strikes, magnetic locks, door position switches, and request-to-exit devices that require power or signal conductors routed through the hinge barrel. It is appropriate for use on hollow metal doors and frames in commercial access control installations where concealed wiring is specified.

Key Features

• 4.5-inch hinge size accommodates standard commercial door and frame preparations
• Supports both 2-wire and 4-wire conductor configurations in one hinge
• Concealed wiring pathway eliminates exposed wire loops or door-frame conduit runs
• Designed for access control and electrified hardware integration
• Sold individually as a single unit

Compatibility

Designed as an OEM-style electric hinge replacement or new installation component for commercial door openings requiring concealed low-voltage wire transfer through the hinge point.

Installation Notes

Installation should be performed by a qualified electrician or credentialed access control technician in accordance with NFPA 70 (NEC) and applicable local codes. Disconnect and de-energize all power to the door hardware circuit before beginning work. Verify conductor gauge and insulation rating are compatible with the intended load before pulling wire through the hinge barrel. Do not exceed the rated conductor capacity of the hinge or subject the wire passage to mechanical stress from improper hinge alignment.
