Torsion springs are secured horizontally across the top of your garage door if you have a sectional or panel garage door, located at both the left and right-hand side if you have a tilt door, and internally fit horizontally if you have a roller door.
  • TORSION POLE: A solid steel rod that the torsion springs are fixed around
  • WEATHERSEAL: This is a rubber strip of varying thickness that prevents wind, rain, debris, etc., coming through the bottom of your garage door. It also assists in evening out the floor level if your garage floor level is not straight
