The Main Drain Cover fitting is made from UV stabilised heavy duty PVC plastic. The universal cover is concrete filled to maximise weight. Designed to prevent suction cleaners from becoming stuck on original grate style covers. This easy fit Slimline model has a height of 25mm, diameter of 240mm and weighs approximately 700g.
Smaller weight to suit shallow main drains - typically fibreglass pools. The extended base retains it in the main drain hole 90mm long. (Not intended for use on main drains with active suction.)
