Garage Door Extension Springs

Garage Door Extension Springs
Find the right garage door extension springs for your model door at North Shore Commercial Door. We have one-piece garage door springs and sectional garage door extension springs for sale at affordable prices. Worn or faulty springs can prevent your garage door from opening, or allow it to free-fall shut. This can damage your door and its components, and create a serious hazard to anyone who enters your garage. All our springs meet current safety standards.

North Shore Commercial Door has several types of garage door extension springs for sale. They're available in several colors, including green and white, so it's easy to match them to your current system.

The garage door springs in our catalog are designed to work with door heights as low as 7 feet and as high as 14 feet, so they're ideal for residential and commercial applications. Shop our line of extension springs for door heights of 8 feet, 9 feet, or 10, 11 or 12 feet. Springs are sold in pairs, and they are sold by color code - from white for 10 pounds to tan for 300 pounds. We also carry extension springs accessories, including sheave pulley kits, garage door pulley clevis straps, metal clips, yoke plates and safety cable. If you can't find what you're looking for, we can place a special order for you. Call our technical help line at 440-366-6112, or email us at
