For heavy duty sliding door applications such as larger wardrobes and cupboards in hotels, schools, hospitals and offices, the Double Top is the ideal choice. Designed to support double track sliding timber, timber framed and composite doors of up to 45kg and 16-40mm in thickness, it works silently on nylon hangers and an aluminium track. Door heights can be adjusted easily, a floor guide can be added as an option, and a triple door kit can support openings of up to 2400mm.
