Carol,
The strap is located so that you push a little against the door and just slip the loop over the roller and there then is a little tension on it and it stays in place perfectly.....once the tension is right you never have to unsnap it. We mounted the male snap through the strap, drilled a hole in the flat aluminum shower extrusion and screwed it in place. We then ran the strap around the roller and carefully marked where the female snap would go and pulled the strap and had that female snap mounted at a canvas shop. The Starboard clamp that locks the door down was a draw, cut, trim, and sand kind of project. I think there must be a simpler method, maybe a Velcro strap or some kind of clamp is the answer. I was reluctant to use a small metal bar clamp in case it came off, it could fall into the glass. These doors are so expensive and perhaps unavailable that some solution is wise before the "big one".
