McKinney TA786 Concealed Bearing Hinge | 5" x 4-1/2" Heavy Weight 3-Knuckle
The McKinney TA786 is an industrial-strength, full-mortise architectural hinge designed for the most demanding high-traffic commercial environments. Featuring a sophisticated 3-knuckle design and advanced concealed bearings, this hinge provides a sleek, modern aesthetic while delivering the extreme load-bearing capacity required for heavy-duty openings. It serves as the premier solution for door restoration, offering a clean, high-end appearance for schools, hospitals, and government facilities that utilize 5-inch hinge preparations.
Engineered with vertical and lateral thrust twin anti-friction bearings at both joints, the TA786 ensures a lifetime of smooth, silent operation under heavy stress. These bearings are completely concealed within the knuckles, protecting them from environmental contaminants while providing a tamper-resistant solution for commercial door security. This hinge is a vital component for any solution for door surface repair, as its heavy .190 gauge thickness and standard template screw hole pattern allow for the seamless replacement of failed hardware on high-use metal or wood doors.
