The Essence Basic Sliding Shower Door Kit with Squared Corner Rollers is a header less system that offers a frameless appearance both vertically and horizontally. Smooth and quiet operation is the cornerstone of the Essence Series. Water management is achieved horizontally via the use of the bottom track, and vertically, with the use of our DK98L Clear Seal. The anti-derail/anti-pinch guard features of the squared corner shaped bottom rollers make them unique. For use with only 1/2″ (12 mm) thick tempered safety glass. Stocked in four popular finishes
