General Information : - The standard roller runners are for use with wooden drawers and shelves and are particularly suitable for system 3000 drawers (or use 'S' type hook and pin runners which are also available). The standard runners are available as bottom or side screw fix and are manufactured from steel and epoxy coated. The runner has profiled low friction nylon runners for smooth action and a captive roller track on one side of the runner reduces lateral movement of the drawer. A self-closing action holds the drawer closed automatically. Loading capacity is 25Kg. Sold in pairs.
