    Note: if an electric operator is being used, add 2" (51mm) to the headroom required.

    (1) Garaga recommends the use of torsion springs for improves door operation and increased safety.
    (2) Garaga strongly recommends the use of safety cables with extension springs for security.
    (3) If you have more than 15" (381mm) of headroom available, 15" (381mm) radius tracks are available on request

    Headroom calculation:

    (Please refer to drawing below)


    1. Measure the distance between floor and ceiling = H
      ex.: 14 ft. or 4270 mm

    2. Measure the door opening = h
      ex.: 12 ft. or 3658 mm

    3. Substract 2 from 1
      1 - 2 = Available headroom
      • The result (H-h) is greater then 406 mm
      • The result (H-h) is less then 406 mm
       

    P.S.: Option

    Low headroom hardware allows you to have very little headroom : between 4" (102 mm) and 11" (279 mm). Contact Garaga for more information

    Note: if adding a garage door opener onto an existing door: if you have 12" (305mm) headroom with torsion spring operation, and you would like to install an electric operator, special top brackets (quick turniing brackets) are available.
