This box is great for large applications such as golf courses but is also a suitable size for the home. There's no need to worry about different colored fittings or plugs to inventory because as well as accepting 2", 3" & 4" pipe, Polylok box can also accept 6" pipe. Our 20" Round Catch Basins will also accept Polylok 20" Risers so you can easily bring the Drain Box to grade.
