Description:
Residential sectional garage door springs counterbalance the weight of the door to make it easy to open and close. They serve the same purpose of counter weights used to balance doors in centuries past and in many doors today. For example, if a garage door weighs 300KG, a spring force of 300KG needs to pull against the weight of the door. This can be accomplished with springs that either stretch or torque special parts to assist in balancing the door.
