Review on 6219 Sliding Plastic Construction: Durable and Versatile Products for Easy Assembly by Darnell Murphy

I was looking for this for sliding shower doors for a customer who was renovating and wanted to reuse their doors. This was perfect for their doors, but there are many sizes so measure before you buy. Very easy to install with a single screw on the inner shower rail. Quick tip: add some silicon under the plastic to make it hold up better than a single screw because when they break it's usually on that screw.
