The biggest difference between Torquemaster springs and torsion springs is their size and ease of winding / installation. Torsion springs are located above the garage door, while Torquemaster springs are located inside a steel tube above the garage door. This makes Torquemaster springs safer to work with because if they break or snap they are contained in the steel tube, and they are wound using a drill instead of torsion spring winding bars. Another difference is the way the springs are wound. Torsion springs are wound tightly and can be dangerous to handle if they are not properly secured. Torquemaster springs, on the other hand, are wound inside a steel tube with a drill, which helps to keep them secure and makes them much easier to handle.
