Extension Spring Safety Cable Install & Replacement
Missing or frayed extension spring safety cables in Fort Collins? Code-required containment cable install and replacement, usually under an hour.
Safety cables are the thin containment cables that run through your extension springs. They are not the same thing as lift cables — if the cable that lifts your door snapped and the door is sagging on one side, you want our garage door lift cable repair page instead. Safety cables have one job: keep a broken extension spring from flying across your garage like a projectile. If yours are missing, frayed, or worn, this is a quick, cheap fix that could prevent a serious injury.
