Garage Door Springs
Torsion Springs
Extension Springs
Extension springs on the other hand, are mounted on the frame of the door or in the pulley assembly of a garage door system. Extension springs manage a garage door’s weight by expanding or contracting while the door is moving. While the contracting spring forces a garage door up toward the ceiling, the expanding spring counterbalances the weight of the garage door. Extension springs, like torsion springs, should only be maintained by a very knowledgeable professional, because of the tremendous forces associated with them.
