This specialty spring is made only by Wayne Dalton for their Torquemaster TMS garage door system. This kit includes easy to follow DIY installation instructions, the correct size plus style TM3 replacement spring(s) for your door weight, and the compatible winding assembly and cable drum kits to convert the original TM1 springs to the newer style plus springs. This is all you need to make the switch from the original to the plus style torquemaster springs. To order, you must know the height and weight of your garage door. Measure door height or find the label on the metal spring tube listing your door dimensions. For doors 6'6" - 7'5" choose 7ft height. For doors 7'6" - 8'2" choose 8ft (available on our other listing for 8ft doors). The most important information when ordering a spring is your garage door balance weight. Springs are specifically rated for a range of door weights, so this detail is required to receive the correct spring replacement. Usually the weight is listed on a label located on the metal tube. If it isn't you can use a bathroom scale to weigh your door. Make sure all spring tension is release prior to weighing. The cables must be fully slack on both sides to insure you are getting the full weight on the scale. Once you have the weight, select the weight range that your door weight falls within. If you select a higher or lower weight than your actual door weighs, the spring you receive may not work.
