Winding the torsion spring requires using 18-in. winding bars made from 1/2-in. diameter cold rolled steel (which is not a typical toolbox staple). Drums at each end of the torsion-spring bar hold the cables that help lift the heavy door. The top panel of this door includes the window design.
In pursuit of the quietest door operation available, homeowner Jeremy Hollingsworth upgraded his old door openers to the PDS800 models from Precision Overhead Door Service. These energy-efficient, DC-powered operators run at an AC-equivalent speed. The DC drive motor features soft-start and soft-stop for smooth, quiet, long-term reliable performance. The efficient design results in ongoing energy savings, and if the obstacle-sensing beam is crossed when the door is closing, the door reverses to fully open. Linear remote controls operate over a long range and employ high-security technology. Plus, the built-in 100W MAX light illuminates the garage for five minutes every time the operator is used. Precision offers a lifetime warranty on the motor, the belt and the labor. Visit precisiondoor.net.
