An industry first, the TorqueMaster counterbalance system helps prevent injuries that can be caused by the exposed springs generally used on garage doors. These springs contain a significant amount of force - approximately 44 inch-pounds per turn. The torsion spring on a 7-foot-high garage door typically has 16 turns, translating to 704 inch-pounds of force contained in the spring. The TorqueMaster system shields springs - and their dangerous force - safely inside a steel tube. |
