  • Suitable for 1-car / 2-car 7 ft high door (8' x 7', 9' x 7', 16'x7')
  • Capacity: 1 pair garage door spring rated for 120 lbs; spring length: 25 inches, fully stretched length: 71 inches
  • Packing Included: Each package includes one pair of Garage Door Extension Springs, one pair of Non-Slip Gloves, and Installation Instruction
  • High Quality: Crafted from professional ASTM-A228 spring steel coils, heat-treated for exceptional durability. Utilizes the latest electrophoretic coating technology for superior corrosion resistance and tensile properties. Withstands 300 hours of salt spray testing and a minimum of 16,000 cycles (a cycle represents one open and close of the door), eliminating the need for maintenance and keeping hands clean during installation.
  • Double Loop Ends: Features double looped ends for enhanced sturdiness, with two coils of the spring connecting to the eye-bolt and pulley. Blesseras exclusively offers double looped ends as the preferred replacement option.
  • Importance of Replacement: Blesseras strongly recommends replacing springs in pairs to ensure balanced operation and safety. As both springs typically wear at the same rate, replacing only one can result in unequal pulling force, potentially damaging the door and opener.

Nice springs, but I made the mistake of guessing which LBS to choose. Unfortunately I needed 170 lb springs for my door. Make sure you put a scale under the unsupported garage door to determine the right choice. (I will not be returning the 120 lb springs, because it was my error). Nice gripping gloves included.
