Thaisan7,Garage Door Torsion Springs .218 x 2" Pair xSpring Length: 28", With Winding Rods, With Center Nylon Bushing

How to select the correct spring (Please Read in Product Description and see detail step1-4 in picture) 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. (Please see detail in 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" ( Raynor doors use 2 ¼” ID ) (Please see detail in picture No.4) Step 3 is to measure the length of the spring, Measure the spring only, not including the winding and stationary cone.(Please see detail in picture No.4) 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. (Please see detail in picture No.4) 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.(Please see detail in picture No.5)
