Hinges – Using a 4 Inch – 5/8 Hinge Where a 4 Inch 1/4 Hinge Used to Go

hinges

I have a door with 3 hinges that are 4 inches – 1/4 inch radius on the corners. Finding a specific hinge with the same hole pattern seems to be impossible to find or extremely expensive.

Is there any issue with using a 4 inch 5/8 radius radius instead? Obviously it would fit. But the reverse would situation would not fit.

Why exactly are their 2 or 3 different sizes corner radius's? Is it a structural thing or simply esthetics?

Best Answer

Hinges all used to have square corners, the rounded corners are to allow machines to cut the recess for the hinge more easily. the corners are not structural.

If you are confident using a chisel replacing your rounded hinges with square ones may be another option.
