We're glad to offer Zurn's Perma-Drain trench drain and 9" - 20" drain boxes from Polylok.
Polylok’s polypropylene drain boxes, available with different capacities and with square or round covers, offer a lot of flexibility and durability for piping in any direction. The 20″ drain box also accepts standard Polylok risers to bring it back to grade at any time.View downloads
