I did a search here as well as a internet search, but I could not find what I was looking for. My roll up door has a 2-3" gap at the top where it meets the front wall. If you stand in front of the door and look straight up you see the gap. I need a seal that is flexible to seal the ribs in the door. I tried putting a 1x4 across the gap, but the door hangs it going up and down. It needs to be flexible because the gap is larger when the door is down, because the roll is smaller and the gaps gets smaller as the roll gets larger.
What is used as a seal on the roll ups that any of you have?
