Manufacturers have made great strides in improving the safety of garage doors and garage door openers. One of the biggest improvements is the addition of photoelectric eyes on door openers manufactured since 1993.
Photoelectric eyes are mounted above the floor and cause a closing door to reverse when movement is detected in the door opening. If you have an older style door opener, consider replacing it with a new one that has all the latest safety features. A new opener costs from $100 to $150 and can be installed by a homeowner in two to four hours.
A second safety improvement is adding a containment cable to extension spring- type doors (Photos 10 and 11). (Extension springs are mounted above the roller tracks.) When an extension spring breaks, the spring and cable become a heavy whip that can smash into cars or unsuspecting victims. A containment cable stops the recoil.
Containment cables cost only $4 each and are available at home centers. Follow the steps in Photos 10 and 11 to install one.
