These doors were a well-embraced mechanism that allowed homeowners to open their garage doors remotely from the comfort of their cars without the need to step out of their cars to open heavy garage doors by hand. This has been by far the most useful garage door invention in the history of garage doors. The leading manufacturer of garage doors openers are selling thousands and thousands of garage door operators on a yearly basis. Such manufacturers invented numerous safety features that allow common households to have and operate automatic garage doors more safely. One of the most noted invention was the photo-eye sensors that allow an operating device to check for any obstructions when prompted to operate. This keeps children, pets or vehicles away from danger by disabling the garage door close shut on someone or something. Once the signal is received and it is perceived as an obstruction, again, the door will be retracted into its open position. Find more about garage doors at http://www.charlottegaragedoorguys.com
