Our CRL Serenity Series Sliding Door System has an entirely different look from traditional sliding shower door systems. The use of minimal hardware provides a frameless look that gives the enclosure an almost floating appearance. Specially designed roller bearings allow for quiet, easy opening and closing of the door. This unique roller system operates above the header support bar that spans the top of the enclosure. One sliding and one fixed panel make the 180 Degree Deluxe Kit beautiful and practical.
