Your roller garage door comes with a remote to automatically open and close it. When you are approaching the garage door, you simply press the button on your remote, and the door opens by the time you reach the garage. Then, you drive in, press the button again and the door automatically closes. The Genie garage door opener utilizes their Intellicode software that changes the passcode that is transmitted from their garage remote to the garage to open it. You never have to worry about some electronically stealing your passcode, copying it, and opening it without your persission.
In response to the inherently dangerous old style garage spring issues as above, a newer and safer system for opening the overhead garage door was created. The idea was to transfer the load or weight of the door via a cable and pulley system to a vertical rod now equipped with a torsion (twisted) spring. This type of spring is installed with specialty hardware and bolts to a fixed plate at one end, while the entire spring is installed around a horizontal pipe. This load balancing device is normally installed directly over the header of the garage opening. Using appropriate cables, connectors and pulleys, the weight of the garage door is transferred into the torsion spring system. The difference between the old style stretched spring and the newer torsion spring is the way that the spring energy is stored. With the old style stretched spring, the energy is stored and released by pulling on the spring or returning the spring to its un-stretched condition.
