Finefit's Retractable slider fitment has a unique style of operation, otherwise known as a collapsible window/door. The type of mesh used in this fitment is a pleated mesh (Fibre & Poly-propylene mix). This sliding system is best suited for large openings, Courtyards & Balconys. The frame of this fitment system is made of heavy Aluminium sections to avoid bend or instablility when doing larger screen fitments. Retractable Tripple slider fitments are used for Door openings that are 4 to 6 meters wide.
