The door rolls in front of or behind of the fixed glass panel, so bathroom floor space is never compromised whether the door is opened or closed. When necessary to fully enclose the shower area, more fixed glass – such as a 90-degree return panel – can also be installed. In some applications a dual rolling door may be better suited to meet your needs. In this configuration both pieces of glass are operable and roll left to right along the same bar. Be assured that with either option, ABC Glass and Mirror will carefully measure your space and construct your rolling “barn style” frameless shower enclosure from glass fabricated to the appropriate specifications.
