    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
