Determine What Size Roll-up Door Springs You Need

It is very important that you order the proper Self Storage Door Springs or Mini Warehouse Door Springs for your Roll Up Door. You will need to make several important measurements that must be accurate. If you are not careful when you make these measurements, your roll-up door may not work as it did before.

To measure Roll Up Door Springs, follow each of the following four steps carefully. 

(1) Measure Spring Wire Size

(2) Measure Spring Inside Diameter

(3) Measure Spring Length

(4) Determin Wind of Torsion Spring (Left Wound or Right Wound)

 

WARNING:

Torsion springs and related door hardware can cause serious injury or death if not handled and installed properly. Professional installation is recommended.

DO NOT attempt to install springs or hardware yourself unless you have the proper tools, reasonable mechanical aptitude and experience, and upper arm strength. Read and understand all instructions before you begin work.
