Q: Will this fit if the Height on mine is 34"?

My unit is 34-1/2" high. It worked okay, but the cords around the bottom didn't cinch up very tight and I ended up having to tie some clothes line rope to tie around the entire base to keep the wind from filling it up and blowing off. My deck does catch wind, but if the cords worked better, it shouldn't have been an issue. If your area is more protected it should be fine.
