To Weigh Your Door:
1.
Raise door completely. Disconnect power and lifting arm of garage door opener.
2. Fasten "C" clamps or vice grips under bottom rollers to retain door.
With tension completely off extension springs, disconnect springs from track
support.
3.
Remove "C" clamps or vice grips and lower door by hand. Note that entire
weight of door, which could exceed several hundred pounds, has to be
lowered slowly by hand so more than one person is needed.
4.
Set bathroom scale to zero and place under center of door and record door
weight.
5. If door weight exceeds capacity
of the scale, use 2 bathroom scales. Add a 2 x 4 with one end on one scale
and the other on a second scale with the door perpendicular to the 2 x 4.
Add the respective weight from each scale together to get the total weight
of the garage door.
