1 Measure The Overall Length Of The Spring--UNWOUND.Take all your measurements from the broken spring. Measure the spring only from coil to coil. Do not include the winding and stationary ends.
2 Measure the Inside Diameter Of The Spring It will be one of the following:
1/4" Raynor Garage Doors only
Look for a number imprinted on the winding end(shown above).
1.75=1 3/4" I.D. 2.00=2" I.D.
If it says Raynor it is a 2 1/4" I.D.
Also Measure the length of 20 Coils 20 Coils measures 4 1/2"=.225 wire size.

the Spring is Left Hand Wound.
Look at the end of your spring and refer to example below.
If you have 2 springs,
we highly recommend that you replace both springs.
If your spring wire size does not
match the spring chart above, please call for price.
Avoid Having to Repeat The Replacement Process
If your door cycles (opens & Closes) more than 3 times a day, we recommend our High Cycle Option. An inexpensive upgrade that will double the spring cycle life from 10,000 up to 20,000 cycles.
What is a High Cycle Spring?
A high cycle spring is a re-engineered spring base on your existing spring measurements(See Steps 1 thru 4) creating a DIMENSIONALLY larger spring. A High Cycle spring has the same IPPT(Inch Pounds Per Turn) or torque as the existing spring but has 50% less stress when fully wound, lasting 2X longer. The installation and the number of turns are the same as the existing spring.
