Super Drain is a technically superior Round Drain designed for maximum flow capacity, durability, and ease of installation. Super Drain features a nailing guide, which also acts as a true water seal against moisture transfer to the subsoil. A full range of non-directional fittings, adapters and end clips are available although you may construct your own out of 1-1/2" schedule 40 P.V.C. pipe. Because Super Drain fits flush on both sides, it stakes securely (no more roll over).
