The Slot Drain® Galvanized Steel drain makes exterior drainage and civil installs easier than ever before. The 6″ wide galvanized segments feature a 0.5% slope and 8″ shallow invert, which continues to 70″ depth.
A 1-1/4″ slot opening will handle up to 27 GPM per foot of flow capacity. Design your drain around flow requirements that you need. Segments mechanically lock together with stainless bolted flanges to create a secure, lasting joint.
