Storm Drain – Slimline Pit with Green Plastic Grate

The RELN Storm Drain Slimline Pit is used at the end of Storm Drain channels to enable lower pipe connection, allowing pipe work to run beneath concrete slabs for vehicular applications. The Heritage Green Plastic Grate is a concave profile, making it perfect for use in paths, driveways, courtyards and trafficable areas.

RELN Storm Drain is the complete surface drainage solution, with a range of different accessories and grate options, perfect for paths, driveways, and domestic areas with corners, T sections and X sections. With its deep 100mm profile, Storm Drain effectively collects and distributes large volumes of surface water throughout its system. The interchangeable clip in grates, hold-down feet and pipe cut-outs make it easy to install, whether you are a DIYer or a professional.
