McKinney T4A3786 CC8 Heavy Weight Electrified Hinge | 5" x 4-1/2" US26D
The McKinney T4A3786 CC8 is an elite, industrial-grade electrified hinge specifically designed for high-density security applications on oversized or heavy-duty doors. Featuring a 5-inch height and a sophisticated 8-wire (4-circuit) configuration, this Concealed Circuit (CC) hinge allows for the invisible and secure transfer of power and data from the frame to advanced door hardware. It is the ultimate solution for door restoration in mission-critical environments like hospitals, university campuses, and high-security government facilities.
Engineered with a massive .190 gauge thickness, the T4A3786 CC8 provides maximum structural support for high-traffic openings. While the ANSI/BHMA A156.1 standard requires only 350,000 cycles, McKinney’s electrified hinges have been cycle-tested to 3,700,000 operations—exceeding the industry requirement by over ten times. This unmatched longevity makes it a permanent solution for commercial door security, providing a reliable electrical path that outlasts standard hardware.
Key Features & Performance
- 8-Wire High-Density Configuration (CC8): Provides 4 individual circuits using 28-gauge wire, enabling complex electrified functions such as request-to-exit (RX), latch bolt monitoring, and high-draw power needs.
- Heavy Weight Structural Integrity: The .190 gauge steel construction acts as a permanent solution for door edge reinforcement for the heaviest institutional doors.
- Vandal-Resistant Security: Wires are concealed within the hinge barrel and protected by brass eyelets, creating a tamper-proof solution for door security that remains invisible when the door is closed.
- UL Listed for Fire Safety: Fully approved for use on fire-rated door assemblies for up to 3 hours, ensuring compliance with strict life-safety and building codes.
- Oil-Impregnated Bearings: Features self-lubricating, non-ferrous bearings that resist clogging and corrosion, ensuring smooth, silent operation in high-traffic corridors.
- Superior Electrical Capacity: Rated for 4.0 Amps continuous at 24V AC/DC per circuit, with a 16.0 Amp intermittent pulse capacity for hardware like electric latch retraction.

Important Installation Notes
The McKinney T4A3786 CC8 features a Non-Rising Steel Pin with button tips for added security and ease of maintenance. This hinge is a robust solution for door surface repair when converting oversized manual openings to advanced automated access control. Ensure that the frame and door are prepped with a 1/2" diameter "snake hole" to prevent wire insulation damage during the hanging process.
Why Choose the McKinney T4A3786 CC8?
The McKinney T4A3786 CC8 is the professional’s choice for large-scale security deployments that require high-density wiring through a single, heavy-duty hinge point. By concealing 8 wires within a 5-inch heavy-weight barrel, you eliminate the risk of wire tampering and physical damage common with external power transfers. It offers a permanent and cost-effective solution for door security, delivering industrial-grade reliability and the polished architectural finish required for modern healthcare and educational facilities.
