Feature

●Includes 1 Left Wound Spring, Wire size is .250, Inside Diameter is 2".
●Please read the complete listing for instructions on how to measure a torsion spring, Our springs are made in the USA using Oil Tempered, USA made Wire, - this makes for a spring that is durable and will outlast imported springs. Cycle rating depends on the spring size and how many turns are required, *Winding and Stationary cones are included and are Pre-installed ((Cones are imported). Our springs include a 2 year limited warranty against pre-mature failure.
●First of all it is very important to have the correct spring for your door, if the spring is not matched correctly to the door, it will not work properly and can be dangerous or damage your operator. Make sure that you measure the spring correctly and if you have questions, please message us before ordering (See detail step1-4 in picture No.3-5)
●CAUTION: Installing or repairing a garage door can be dangerous task. Garage door springs and cables are under extreme tension and require appropriate safety precautions. Working with garage doors and openers could result in personal injury or death. We recommend all installations, repairs, adjustments, and removals on garage doors be made by a qualified garage door technician.


Description

How to select the correct sprin,

Step 1 is to measure the wire diameter. To do this you will need to measure 10 coils then compare that measurement to the chart below to see the wire size,double check by measuring 20 coils and compare to the 10 coil measurement, if the 2 measurements do not match, try measuring in a different area of the spring and also make sure the spring is not stretched. Do not measure in the ends where the cones are, the cones stretch the ends where they are installed.(Please see table detail picture No.3)

Step 2 is to determine the spring inside diameter, if the spring is broken you can simply use a ruler to measure the inside of the broken end, if the spring is still in one piece you can measure the outside and deduct the wire size X 2. You also may be able to find stampings on the cones which will help determine the ID, ( P200 or P2000 for 2” and P175 for 1 ¾”) The most common sizes in residential springs are 1 3/4" and 2" ( doors use 2 ¼” ID )

Step 3 Step 3 is to measure the length of the spring, Measure the spring only, not including the winding and stationary cone. If the spring is broken measure each piece and add the two measurements together to get the total length. If the spring is still in one piece and wound, it will be longer by 2-3” then when it is relaxed.the proper way to measure is to unwind the spring to measure the correct length.

Step 4 is only important if ordering a single spring, determine the wind direction of the spring, ( right hand wind ( RW) or left hand wind (LW). Below is an example of the different spring winds. This is probably the most confusing part of the spring ordering process, as The RW is normally on the Left side and the LW is normally on the Right side. Be sure to check the wind direction and not make assumptions. If you look at the end of the spring and compare to the picture below, you will be able to determine the correct wind direction.(see picture no.5)
