Select the type of spring supply you need. We’ll show the relevant fields.

How would you like to specify it?

Selection help uses door and existing-system details. It does not calculate a replacement automatically.

Specify springs per assembly below. Left + right pair means two springs per set. Timing is a request; we confirm lead time and shipping with your quote.

3Spring specifications

Enter the core dimensions below. Ends, hardware, and finish can be confirmed later.

Use unwound spring body length, excluding cones. These fields capture your request; they do not confirm that a size combination will fit or be available.

Built for professional spring supply

Can I request 10-foot springs?

Yes. 120-inch long-length torsion options are available in selected specifications, including 1.75-inch and 2-inch inside diameters. Other lengths and configurations are quoted individually. Please confirm the required finished spring specification and installation space.

Can you help with higher-cycle replacements?

We can review supply options for your operating needs. Higher-cycle replacements must maintain the correct counterbalance characteristics and fit the available shaft space. Increasing spring length alone does not establish compatibility.

What if my spring has unusual ends?

Select the closest end type, then include markings and a photo reference. Self-storage, rolling steel, and legacy configurations require identification before supply is confirmed.

Can I order several sizes or repeat the same order?

Select bulk or repeat supply and list each specification and quantity in the project notes. Include a P.O. number and job name so your request can be matched to the project.
