For new designs and changes to existing designs we suggest you call and talk to one of our design specialists. There are many questions that need to be answered to supply you with an extension spring that works and is cost effective. Our design specialists are trained to help you answer these questions.

For existing designs we ask that you fax or email a current print or send a sample. With a good pair of dial calipers you can measure the spring and fill in the information required below.
