I love the end product. The door fits well with my shower opening, but getting the nuts that attach the rail to the fixed side took a while. Hard to thread and tighten down. If they had a bit more thread before abutting to the glass, it would be nice. After several attempts, finally got them to seat, but only with about 1 1/2 turns on the thread. I'm hoping it's enough... Otherwise, a good product.
