McKinney T4A3786 CC4 Heavy Weight Electrified Hinge | 4-1/2" x 4-1/2" US26D
The McKinney T4A3786 CC4 is an industrial-grade, heavy-weight electrified hinge engineered for high-traffic commercial environments. As a Concealed Circuit (CC) intermediate connector, it facilitates the invisible and secure transfer of power from the door jamb to electrified hardware, such as electric locks and exit devices. This hinge is a premier solution for door restoration in facilities that demand extreme durability, such as hospitals, schools, and high-security government buildings.
Constructed with a substantial .180 gauge thickness, the T4A3786 is built to support heavy-duty doors under constant use. While the ANSI/BHMA A156.1 standard requires only 350,000 cycles, McKinney’s electrified hinges have passed 3,700,000 cycles—over ten times the industry requirement. This exceptional longevity makes it the ultimate solution for commercial door security, providing a reliable electrical path that outlasts the competition.
Key Features & Performance
- Heavy Weight Construction: Features a .180 gauge steel body, acting as a permanent solution for door edge reinforcement on high-frequency, heavy-duty doors.
- 4-Wire Concealed Circuit (CC4): Utilizes 28-gauge wire to provide two circuits for power or monitoring, ensuring a discreet solution for door security without exposed wires.
- Tested Beyond Standards: Cycle-tested to 3.7 million operations, ensuring the internal wiring remains intact even in the busiest corridors.
- UL Listed for Fire Doors: Approved for use on fire-rated door assemblies up to 3 hours, meeting stringent life-safety codes.
