Measuring Your Broken Garage Door Torsion is as simple as 1 2 3.
Take 3 Simple Measurements Of Your Garage Door Torsion Spring. Wire Diameter, Inside Diameter, and Length of Garage Door Spring.
1. Measuring the wire diameter; The easiest and most accurate way to measure the wire size (because it is so small) is to count 20 coils on the broken spring and measure just that section to the nearest 1/8", then devide that measurement by 20 or see chart below. Ex. if your 20 coil measurement came out to exactly 5", then your wire size is a .250.
2. Measuring the inside diameter; This is pretty cut and dry. Measure straight across from inside the coil to inside of the other side of coil, where the spring is broke. Your measurement for residential doors will either be 1.75" or 2". If and only if you have a Raynor door, you will have a 2.25" inside diameter. In some cases you will find this size on the cone.
3. Measuring the overall length; This is the easiest of the three measurements. Simply measure from the 1st coil to the last coil. Do not include the end cones, and be sure you are measuring the broken or unwound spring.
(Please be certain both springs are the same in measurement.)
