The circular shaped Header and the round Rollers of the Capri Series Single Sliding Door System are the perfect complement to each other. They help provide a luxurious sliding shower door system and a soft décor. The use of minimal hardware lends itself to the popular modern sliding shower door systems by showing more glass, and less hardware. These quality Rollers assure quiet door travel, and make the door easy to slide. The Crescent Series Sliding System accommodates 1/2"or 3/8" (12 or 10 mm) thick tempered safety glass (not included), and the system allows that the fixed and sliding panels are reversible for installation as desired. The Crescent Series Sliding Door System is available in a choice of polished stainless steel, brushed stainless steel, or the new popular matte black finish.
