Another key safety feature to prevent entrapment from garage doors is the “electric eye” sensor system found on many more modern garage door systems. Sensors placed on either side of the garage door’s track system about 4 to 6 inches off the ground transmit an infrared beam of light during a door’s closing operation. Should anything break the beam during the closing operation – including adults, pets or other objects – the opener should automatically stop and reverse the closing operation.
Center and level the first section after you install the brackets. The door must be level even if the floor isn’t, so use shims under the section to level it. The rubber gasket on the bottom section will fill the gaps created by an unlevel floor. To hold the level in place, tape it to the section. To hold the section in place, lightly toenail a 16d nail into the frame and bend it over the section. Add brackets and rollers before setting them in place and stack one section on top of another, toenailing as you go up.
They sent Doug Fussell out to my house on the day after Christmas! I had only called them three days before! Doug was a premier technician, very thorough and very efficient. I expected him to take two days, since he was replacing two doors and adding openers on each door. He only took the daylight hours of one day! I could not believe how fast he was! In addition, he thoroughly taught me how to use the remote openers. I highly recommend them to anyone!
