Commercial Garage Door Torsion Spring

With standard garage door springs lasting about 10,000 cycles, it’s inevitable that your commercial garage door torsion springs will eventually need a replacement. That's why we supply these 3 3/4-inch interior diameter springs to instantly get your doors working like new. Our springs are great for roll-up doors, overhead doors, and other industrial applications.

When ordering your springs, keep in mind that they tend to give out around the same time. So even if only one of your springs is broken, it’s best to order them in sets of two. If you have any questions about this product, use the handy “Questions” app below to get more information from our staff.

Wire Size:

A spring’s wire size can be determined by several different tools or techniques. Use of a caliper, micrometer, or wire gauge are common ways to determine a spring’s wire size. If none of these tools are available, simply measure ten coils of wire to the nearest 1/16th of an inch, and refer to the Spring Wire Chart. The spring must be tightly compressed, with no gaps. It’s also a good idea to measure twenty coils as a double check. Wire Size

Inside Diameter:

Measure the inside diameter to the nearest 1/16th of an inch. In most cases, the cones inserted in each end of the spring will have a manufacturers name (OHD or Raynor, etc.) which will give a clue toward the proper identity. The chart on the right shows common ID’s used by various manufacturers. If no manufacturers name is evident, usually a part number on the cone will indicate the inside diameter: 134 or 175 = 1 3/4" ID 258 or 263 = 2 5/8" ID 375 or 334 = 3 3/4" ID Inner Diameter

Length of Spring:

Measure spring length with the spring in its unwound state. In the case of a distorted or broken spring, simply count the total number of coils and multiply by the wire size. 120 coils x .250 wire = 30" 120 coils x .375 wire = 45"
