Survey your garage area to see if any of the conditions below apply to your installation. Additional materials may be required. You may find it helpful to refer back to this page as you proceed with the installation of your opener.

Depending on your requirements, there are several installation steps which may call for materials or hardware not included in the carton.

  • This opener is compatible with:
  • Doors that use a torsion bar, springs, and a door no more than 14' (4.2 m) high
  • 4"–6" (10 cm – 15 cm) drums, not to be used on tapered drums over 6" (15cm)
  • High lift and standard lift sectional doors up to 14' (4.2 cm) high
  • Doors up to 18' wide
  • Doors up to 180 sq. ft.
  • 1" (2.5 cm) torsion bar only
  • Review or inspect proposed installation area. Opener can be installed on left or right side of door. Select the side that meets the requirements listed below:
    • Must have minimum of 2 – ½" (6.4 cm) between the garage wall and the center of the torsion bar
    • Must have minimum of 3" (7/6 cm) between the ceiling and the center of torsion bar
    • Must have minimum of 8" (20.3 cm) between the side garage wall (or obstruction) and the end of torsion bar
    • The torsion bar must extend at least 1" to 5" (2.5 cm to 12 cm) past the bearing plate
    • An electric outlet is required within 6" (1.8 m) of the installation area. If outlet does not exist, contact an qualified electrician
    • Depending upon garage construction, extension brackets or wood blocks may be needed to install safety reversing sensors
    • Alternate floor mounting of the safety reversing sensors will require hardware not provided
    • A model 475LM EverCharge Battery Backup System is strongly recommended if there is no access door to the garage, as this opener cannot be used in conjunction with an external emergency release mechanism
    • Any gap between the floor and the bottom of the door must not exceed ¼" (6mm). Otherwise the safety reversal system may not work properly

NOTE: Inspect the torsion bar while the door is raised and lowered. It is important that there is no noticeable movement up and down or let and right. If this type of movement is not corrected, lift of this opener will be greatly reduced.
