Hinges
 
Template

Five knuckle, ball bearing 4 1/2” h x 4” w with ball bearing template hinges are the standard for 1 3/4” hollow metal and wood doors.  Standard weight steel hinges (.134” thick) with a satin nickel (C15) or statin chrome (C26D) finish are typically used for 3 x 7 interior doors.

Continuous

The fact that geared aluminum hinges distribute the stress of carrying the door over the length of the hinge makes them ideal for high traffic applications where template hinges would have a shorter life cycle. Full Mortise continuous hinges are typically ordered for new doors and frames.

Spring

These standard concealed bearing hinges contain an internal spring that can be tensioned. They are ideal for low weight doors in low traffic areas where the installation of an overhead door closer is not feasible or desirable. The size of the door governs the number of spring hinges required. For a 3 x 7 door, we recommend two spring hinges.
