The McKinney 1502 Spring Hinge is a high-performance, self-closing hardware solution designed to provide a sleek alternative to traditional overhead door closers. Engineered for standard-weight, medium-frequency doors, this full-mortise hinge is the premier solution for door restoration in apartments, hotels, office buildings, and motels.

Application & Installation Guidelines
To ensure proper latching and NFPA compliance, please follow these weight-based recommendations:
- For Doors up to 115 lbs: Use two 1502 spring hinges and one equivalent size ball bearing hinge.
- For Doors up to 150 lbs: Use three 1502 spring hinges for maximum closing force.
Note: Proper latching can be affected by gasketing, wind conditions, and air pressure. For doors with heavy smoke seals or unbalanced HVAC pressure, a third spring hinge is often the best solution for door restoration to ensure a positive latch.
