Hollow Metal Doors & Frames, Architectural Hardware
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.

A variety of other finishes are also available – brass, oil rubbed bronze etc. Standard weight stainless steel hinges (630) are recommended for exterior doors.  When ordering hinges, make sure that you check the finish you are getting because there is more than one way of designating the same finish. A handy finish chart is in the resource section for your use.


Heavy Weight 4 1/2” x 4” hinges are recommended for doors 3’6” and wider as are 5” h x 4” w hinges.  Where doors 7’0” or less have 3 hinges; doors higher than 7’0” to 9’0 require a 4th hinge to support the door.  When you install doors that are heavy or high, make sure you block the door and use a helper so that there is no stress on the hinges when you install them and do the top hinge last. This is because 75% of the stress is on the top hinge alone. Failure to do this may cause the door to sag against an adjacent door or jamb.

We appreciate the time frame you have given us to have the doors done. We were very happy with the first one, and are very excited to have them all done!
