Menus are sometimes hierarchically organized, allowing navigation through different levels of the menu structure. Selecting a menu entry with an arrow will expand it, showing a second menu (the sub-menu) with options related to the selected entry.
Torsion springs are normally mounted horizontally above the opening of your garage door. When you pull the door down, cables attached to the bottom corners actually force the springs to wind up, in turn energizing the system.
Hereâs what you should know about what they do, how they affect the lifecycle of your garage door, and what to do when theyâre in need of repair. Just like any spring, garage door torsion springs store mechanical energy, which makes them tighten. Torsion springs store energy by using a rotating or twisting motion. The advantage of garage door torsion springs over conventional springs is that they can store lot more energy because they are made from a denser material.
