CS Cavity Sliders offers a range of heavy duty cavity sliding doors engineered to suit 120mm stud widths.  

Cavity sliders refer to the cavity installed within wall framing that allows a door to slide inside the wall leaving clear space on both sides of the wall and opening while encouraging cohesion between rooms.  

CS Ultimate cavity sliding doors are designed for thicker and heavier specialised or custom manufactured door leaves. CS Ultimate is made to measure for doors up to 4000mm high x 3500mm wide.  

Jambs may be either timber or pre-finished aluminium. While timber jambs suit door thicknesses from 10mm to 68mm, prefinished aluminium jambs suit door thicknesses from 62mm to 68mm.  

The track extrusion on CS Ultimate cavity sliding doors has hidden cells with the option of installing steel bars for extra strength and rigidity. Multiple leaves may be joined to make one extra wide door using the ActaLink system by CS Group.
