GRI PTDC Power Transfer Device with Custom Lengths

Installers and security integrators rely on the George Risk Industries PTDC power transfer device (door cord) to deliver dependable, protected power from door to frame for electric mortise locks, exit devices and other access control hardware. The PTDC combines a stainless steel armored cable with heavy-duty aluminum end fittings to protect wiring from abrasion and tampering—critical for long-term security and surveillance installations. With an internal diameter of 0.218" (5.55 mm) accommodating up to .180" wire diameter and a design that permits a full 180° door opening, the PTDC preserves functionality while enabling continuous monitoring and reliable power transfer in high-traffic environments. Twist-lock cable retention and included mounting hardware and set screws simplify installation and reduce service calls. Available with custom armored cable lengths on request, the PTDC adapts to retrofits and new builds alike.
