Most modern homeowners tend to overlook how complicated and highly involved their garage door system is. People might have an idea of how complex and complicated their garage doors are when they think about it, but few of them do so regularly. Garage doors today weigh up to 350 pounds, and that is a lot of heavy lifting to be done on a daily basis. These doors are held up by an intricate system of components, and two of the main components are garage door springs and garage door cables. The heavy-duty cables run through the springs, and together these parts help stabilize the garage door and prevent it from coming crashing down and potentially causing serious injury or property damage.
