US Patent 9364121 Sliding shower door assembly

A fully frameless sliding shower door assembly includes a sliding panel of sufficient strength to be fully self-supporting and includes a stationary panel. The need for an upper horizontal header member is eliminated by using an upper guide assembly having a guide which is fixed to the sliding panel and configured to slide about a top edge of the stationary panel. A self-centering roller assembly is attachable to the sliding panel without the need for a rail member. The roller assembly and a track therefore feature matching inverted and non-inverted generally U-shaped profiles. The shower door assembly further features inboard and outboard roller finger guards, as well as a track leveling feature which improves ease of installation.
