These hinges provide spring tension to any door, lid or cap without taking up a lot of room.  Even with their small (3.25 in x 2.75 in) footprint, they pack a lot of torque.

Steel with yellow zinc plating, stainless steel spring, and nylon bushings for quiet operation.  Mounting hardware is not included.

These hinges are designed for long-term usage with corrosion-resistant materials, a quiet operation, and robust spring tension support. Enjoy the convenience of easily opening and closing your doors, lids, and caps, with minimal effort and space needed.
