This straight L head drain has a wide, flat lip on the bottom edge of the flange to allow it to drain all the way down to the deck. The 1-1/2" hose barb is also off-set toward the bottom so water drains into the hose completely. It is molded of UV resistant, high strength Acetyl that resists degradation from sun and sealants. Comes with plastic nut, fits 1-1/2" marine sanitation hose, and has room for double hose clamps. 2" long threads allow this thru hull to fit in tight spaces.
These are the most widely used flat-sided drains in the marine industry -if yours looks like this, it is probably the same make!
