Color Coded Garage Door Extension Springs

Color Coded Garage Door Extension Springs. Oil Tempered, Galvanized, Black Oxide or E-Coated: Wound from high-carbon spring wire and finished in-house, so the springs hold up in unheated, damp and coastal installations. Open Loop, Double Loop and Clipped End Options: All three standard end styles are produced to order and matched to your pulleys, S-hooks and bracket hardware, so the spring seats correctly without fie. Colour-Coded for Lift Capacity: Each spring is marked at the end to identify wire gauge and door weight at a glance, which cuts mis-orders and return claims on replacement business.
