The McKinney T4B3386 is a heavy weight full mortise butt hinge built for high-frequency, high-abuse openings where durability matters most.

The non-removable pin (NRP) adds a critical layer of security, making this hinge ideal for out-swinging exterior doors where tamper resistance is essential. Constructed from 630 satin stainless steel (US32D), it resists corrosion and holds up beautifully in both interior and coastal or exterior environments. This hinge is a reliable choice for commercial buildings, institutional facilities, and any application requiring long-term performance and strength.

The ball bearing configuration reduces friction between the hinge knuckles, allowing the door to swing freely while carrying substantial weight. The non-removable pin locks in place once installed, preventing the door from being lifted off its hinges when in a closed, secured position.
