  • Clearances: refers to the amount of headroom, backroom and side room required to efficiently and safely install a garage door.
  • Cycle: One cycle of a garage door goes from when its fully closed to fully open and then back again to fully closed. (Tort ion sprung doors are rated for how many cycles they are supposed to safely complete in their lifetime).

  • Pneumatic Sensing edge: Serves same purpose as photo eyes, consists of an air hose running along the bottom the door that will reverse the direction of the door if it comes in contact with an obstruction.
  • Radius: Curved part of the track between the vertical and horizontal pieces.
  • Rollers: Consists of and axle and attached wheel that run up and down the track.  Also rated in cycles.  Can be steel or nylon.
  • Sectional Doors:  Doors made up of sections hinged together.  Thus allowing it to bend around the track as the door opens and closes.
  • Side room:  Represents the distance from door jamb to closest obstruction.
  • Spring Assembly: Is either tort ion or extension spring witch counterbalances the weight of the garage door.
  • Torsion Spring: Another type of spring system that aides in raising and lowering the garage door.  They are mounted above the door and are unmentioned and tensioned by the cables as they wind around the drum and the door is opened and closed.
