How many turns do I need to wind the new spring(s)
I full turn per ft of door height plus a 1/2 turn. A 7' high door would adjust to 7 1/2 full turns or 30 quarter turns. Installation Video:PLEASE NOTE, Any variation of your actual spring dimensions will alter
counterbalance and affect the overall life of the replacement spring. Here are the instructions on how to measure your existing spring. If you need help, contact customer support

The spring shown above is a Right Hand Wound Spring which mounts
to the left side of center(Red) End. A spring mounted on the right side of center is left hand wound(black end)Doors that have two springs
have both right hand and left hand wound.
STEP 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.
STEP 2 Measure the Inside Diameter Of The Spring
It will be one of the following:
Look for a number imprinted on the winding end(shown
1.75=1 3/4" I.D.
If it says Raynor it is a 2 1/4" I.D. Please Note: We convert 2 1/4"ID to 2"ID. The spring(s)will be slightly Longer.
STEP 3 Determine The Wire
Measure the length of 10 coils. Refer to Wire Chart. Example: 10 coils measures 2 1/4" = .225 wire size.
Note: Take your Measurements at the point of where the spring is broken and not and the end of spring where there are gaps between the coils.
Also Measure the length of 20 Coils
20 Coils measures 4 1/2"=.225 wire size.
Length of 10 Coils

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
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
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.
