DIMENSION: One pair of 130 lb. heavy-duty yellow garage door extension springs. Each spring is 25 inches long at rest and 67 inches long when fully stretched. These springs fit Tall configurations on residential doors that are no higher than 7 ft.
PACKING INCLUDED: One pair of Garage Door Extension Springs, one pair of Non-Slip Gloves, and Installation Instructions are included in the package, so you can start installing immediately after receiving the product.
HIGH QUALITY: Made from professional ASTM-A228 spring steel coils that have been heat-treated to ensure extremely high durability. The latest electrophoretic coating technology provides excellent corrosion resistance and excellent tensile properties. Salt spray testing lasts up to 300 hours with a minimum of 16, 000 cycles, with one cycle defined as 1 open & close of the door. The springs do not require maintenance and help keep your hands clean during installation.
DOUBLE LOOP ENDS: They are sturdier than open loops because two coils of the spring connect to the eye-bolt and pulley. These springs feature double looped ends, which can replace any other end type. Only double looped ends are offered as the preferred replacement option.
IMPORTANT: Replacing springs in pairs is highly recommended. Typically, both springs are the same age and have similar wear. When one spring breaks, the second spring may also soon reach the end of its cycle and break. A newer spring may exert more pull than an older spring, causing the door to open and close with an unequal amount of pull on both sides. This can damage the door or garage door opener and create an unsafe condition
