Palace Series Bottom Sill Extrusion components were especially designed to add versatility to our Frameless Sliding Shower Door Kits. They allow the option of adding additional panels to create a designer enclosure, or simply construct your own sliding unit by combining the various parts. Stock lengths of Headers, Header Fillers, Side Jambs, Bottom Sills, Sidelite Sills, and Clear Polycarbonate Vertical Jambs, along with Top Hangers and other accessory items round out the items available. Use these components to build the enclosure you require, or we can assist with your design. Email or fax us a drawing (with dimensions) of the shower opening and we will put together a customized kit for you that will include everything you will need (except the glass and the silicone). Installation instructions are included in each custom kit.
