Our slot drains are one of a kind. Heavy duty galvanized stamped steel slot grate rests upon the 4" channel depth of your choice or our 1% Pre Slope Packages.  Connecting to each other with a tongue and groove connection. The slot grate has an opening of 1/2 inch and widens towards the channel. This is a patent feature that allows debris to pass through the slot and not be stuck. Perfect for pools, porches, and any situation where grating is not necessary. Below are specifications.  With our Pre Slope system you can create a run up to 50 ft in length with a 1% slope. With an option of a 4" outlet on the end no matter the channel run length.  Neutral Channels; The 2", 3", 4", 6", and 8" Depth channels have bottom outlet option available with 4" Pipe connection.
