Both sides of this sheep barn has an entrance. Along side each door is the part of the plastic sheeting that rolls up for ventilation. This area of the barn’s design fails, in my opinion. So its my job to figure out a way to keep the plastic from tearing.
So what I come up with is something like a double brace that would allow two tracks to be installed securely.
The door had quite a gap at the bottom as well. A door sweep is all that would be needed, like those found on residential exterior doors. But, there’s nothing commercially available… time to improvise. I took a piece of leftover rubber molding from a commercial job years ago, attached it to the door with a strip of steel and there you have it.
