I have a hinge that I am trying to replace but I need help identifying it. Can you help?

Yes! Please click here to visit our Hinge Finder page.

Some of your hinges are sold by the each and some sell by the pair. What is the difference?

When the unit of measure says “pair” that means two hinges. Usually you need one pair of hinges per door. When the unit of measure says “each” that means one hinge. You would usually order 2 “each” hinges per door.

I want to replace my hinges. How do I make sure the screw holes on the new hinge match the screw holes on the old hinge so I do not have to redrill the holes?

Unfortunately, hinge manufacturers have never standardized the location of their screw hole patterns. Every manufacturer puts their screw holes in a slightly different place. This means that when you replace hinges you will almost certainly have to do some filling and redrilling. The exception to this is Architectural door hinges which are built to a standardized template for each size hinge.
