16 foot wooden garage door, no telling what the door age is. The bottom, middle and top panels already have 2 1/4" (?) struts installed, presumably to correct previous sagging.
The bottom panel is sagging horribly even though has a strut installed across the bottom edge. What would you recommend to fix the sag:
- Replace the strut along the bottom?
- Add another strut along the top edge of the bottom panel?
- Do both (1) & (2)?
I was hoping to do this myself, although I have no way of transporting a 16 ft long strut and will likely be at the mercy of a garage door repair company anyway.
