The shower door was purchased to enhance and allow use of a master shower.  I rated it four out five stars for reasons other than overall quality, design and appearance when installed.  The engineering could use some enhancements such as the lower glide having a full nylon or plastic insert covering the entire chromed metal to ensure silence of the glide door when operating.  The stationary door adjustments on the support bar could allow slightly more alignment adjustment just for additional give in out of plum applications.  The stationary panel should be sealed on the bottom with silicone prior to the sliding door installation to ensure caulk can be properly applied without use of a nozzle extension.  The installation instructions should be in one language for an entire installation and not have four paragraphs in the same instruction section each in different languages.
