McKinney T4A3786 CC8 Heavy Weight Electrified Hinge | 4-1/2" x 4-1/2" US26D
The McKinney T4A3786 CC8 is a premier, industrial-grade electrified hinge designed for high-density access control in high-traffic commercial environments. As a Concealed Circuit (CC) intermediate connector with an 8-wire (4-circuit) configuration, it allows for the secure, invisible transfer of power and data from the frame to sophisticated door hardware like multi-point locks and exit devices with monitoring. This heavy-weight hinge is the ultimate solution for door restoration in mission-critical facilities like hospitals, schools, and high-security government buildings.
Engineered with a robust .180 gauge thickness, the T4A3786 CC8 is built to withstand the physical demands of oversized or high-frequency doors. While the ANSI/BHMA A156.1 standard requires only 350,000 cycles, McKinney’s electrified hinges have been tested to 3,700,000 cycles—over ten times the industry requirement. This unmatched longevity makes it a permanent solution for commercial door security, providing a reliable electrical path that outlasts the building’s lifecycle.
Key Features & Performance
- 8-Wire High-Density Configuration (CC8): Provides 4 individual circuits using 28-gauge wire, allowing for complex electrified functions like request-to-exit (RX), latch bolt monitoring, and high-draw power needs.
- Heavy Weight Structural Integrity: The .180 gauge steel construction acts as a permanent solution for door edge reinforcement for heavy-duty 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 is 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 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 high-draw 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 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 heavy-duty security deployments that require multiple circuits through a single hinge point. By concealing 8 wires within the hinge, 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
