The only hard part about this was getting the panel up the spiral stairs!  Beautiful, solid piece of glass, arrived well packed, assembly was simple and the inclusion of the plastic strips that lie inside the metal track were easy to install and protect the glass. Now we can finish our bathroom project!  It's such a simple, classy looking piece and we are glad to have brought it. And by the way, it can be taken up a spiral staircase by two average sized people (in fact, one of us is tiny!)
