Extension Springs
Extension springs run along the horizontal tracks above the door and stretch when the door closes. Each one's color-coded by lift rating, which makes it easier to match your replacement. We've got S-hook, double-loop, and clipped end styles for doors from 7 feet to 12 feet tall. Oil-tempered USA steel. Swap both sides at the same time — even if only one broke — so the door stays balanced and doesn't ride crooked.
