Which hardware is more appropriate for my garage door? The 2 in. (50 mm) or the 3 in. (75 mm)?
The answer to this question lies in the size of the door and the extent to which it is used. If the door measures less than 150 square feet (14 square metres) and operates at a normal rate, that is to say, 8 cycles per hour at most, the 2 in. (50-mm) tracks and rollers are perfectly suitable. For all other applications, we recommend the 3 in. (75-mm) hardware. Make sure tracks are welded, not riveted, and that they bear the GARAGA name.
