Frequently Asked Questions

What is a SPEC extension spring used for?

A SPEC extension spring with machine hooks is used to provide tension in industrial assemblies such as garage doors, trampolines, and agricultural equipment. It stores energy when stretched and returns to its original length, making it essential for counterbalancing and return mechanisms across many industries.

What are the specifications of the SPEC extension spring 828N56?

The SPEC extension spring (SKU 828N56, MPN MH03600491000M) has a 1-inch free length, 0.049-inch wire diameter, 0.36-inch outer diameter, and an oil finish. It is made of music wire and comes in a 5-pack. These dimensions determine its load capacity and fit for your application.
