what is the weight of a garage door
Garage door A typical version of an overhead garage door used in the past would have been built as a one-piece panel.[1] The panel was mounted on each side with unequal parallelogram style hinge lifting mechanism. Newer versions of overhead garage doors are now generally built from several panels hinged together that roll along a system of tracks guided by rollers.[1] The weight of the door may be 400 lb (181.4 kg) or more, but is balanced by either a torsion spring system or a pair of extension springs.[2] A remote controlled motorized mechanism for opening garage doors adds convenience, safety, and security.[3]
Classic car Cars 20 years and older typically fall into the classic class.
