Bommer Special Spring Hinges

At times door and door frame manufactures have Bommer make special sized and/or special hole pattern door hinges. By special we mean non-standard. They are a very odd size (EX: 4" High x 3-3/4" Wide) or the hinge hole pattern is unique.

Usually you find out your door has special door hinges after you all ready purchased standard type replace hinges from us. You quickly measured a hinge size and corner radius (How to measure hinge corner radius) that needed replacing. Purchase the replacement hinges. Then when installing them you find out they did not fit. All the Bommer Door Hinges sold at have links to downloadable PDF files of the hinges dimensions.

Below are some of the most common Special Spring Hinges manufactured by Bommer that we sell.
