It works, first try!
I added this to my enclosure in about 10 minutes, with most of the time spent just deciphering the one-size-fits-all instructions. the zippers join at the bottom, with a pipe that slides into the sleeve along the bottom of the door flap. has end caps that could hold a dowel or other weight, but it will work just fine as-is. the threading of the cord took some study, but it is very simple to use. The tie-off cleat has no pre-defined attachment point, but possibly could be attached with a couple of zip-ties. I just loop it around part of the frame and tie it with a slip-knot.
- fits on the 10 by 20 enclosure frame nicely. When rolled up, gives enough headroom for SUV or small truck.
- When closed, zips up easily.
- Directions need improvement, with mention of the grommets that are fine for threading the cords, instead of cutting the fabric - I didn't find it necessary to cut it, and I tied the cord on the top support tubes instead. A couple of photos, not line drawings only, would have helped.
