TorqueMaster

TorqueMaster is a proprietary torsion spring counterbalance system designed by Wayne Dalton. Instead of an exposed spring mounted on an open shaft above the door, the TorqueMaster system places one or two springs inside a hollow painted-steel tube. The tube is mounted horizontally above the door opening in the same position as a standard torsion shaft, but the springs and their winding mechanism are fully enclosed within it.

Why Wayne Dalton designed it:

A standard torsion spring that breaks under tension can sometimes produce a loud bang and, in rare cases, can snap or fragment. The TorqueMaster tube contains the spring entirely. If the internal spring breaks, it stays inside the tube. The system also presents a cleaner visual appearance because no coiled spring is visible above the door.

How it is wound:

Standard torsion springs are wound with steel winding bars inserted into the winding cone. The TorqueMaster system uses a proprietary electric winding tool that inserts into the end of the tube. The winding is performed at the tube end rather than at an exposed cone. This means a homeowner cannot service the spring with standard winding bars and must either purchase the Wayne Dalton winding tool or call a technician who has one.

Serviceability tradeoffs:

TorqueMaster springs are available in two formats: original Wayne Dalton replacement springs (available through dealers) and retrofit conversions. Because the system is proprietary, the spring options are more limited than the broad aftermarket for standard torsion springs. When a TorqueMaster spring fails, many technicians recommend converting the door to a standard open-shaft torsion spring system at the same time, because the conversion gives the door access to the full range of standard spring sizes, wire gauges, and cycle-life ratings without requiring proprietary parts.

The TorqueMaster system functions identically to a standard counterbalance system in terms of force delivery. Its spring tension is still transferred through cable drums to the lift cables to the bottom of the door.
