Three main products in the area of garage door spring safety have been introduced in the last 20 years:
Wayne Dalton TorqueMaster springs (shown installed above) wind with a drill. The TorqueMaster is the first system to offer a counter balance spring sealed inside the garage door tube for safety. Because TorqueMaster springs have a smaller mean diameter, they need to be longer to match the lift of a spring. To keep the springs from being too long, however, Wayne Dalton uses a smaller wire size, which leads to problems with cycle life. As a key advantage, if you have two springs on your garage door, there is a winding unit at each end, which makes drill/socket winding a breeze.
Clopay/Ideal EZ-SET springs have their own hardware, winder, and winding cone. Stationary cones can be the standard variety. The shaft has limited room for these. The cycle life on EZ-SET springs somewhat has a limit. However, they have gaps that hold them to the proper length so that the coils will not bind. As a result, these springs appear more slinky-like as compared to standard springs.
Spring King: Industrial Spring’s Spring King utilizes a drill-winding system for use with standard torsion springs. Therefore, Spring King is a product well-suited for the do-it-yourselfer who would be hesitant to face the task of conventional spring winding.
These three innovations increase safety in the garage door business.
