This black 2-piece push together scupper provides excellent drainage while the recessed flapper keeps water out. Inside flange snaps onto ribbed sleeve from outside fitting creating one solid thru hull drain, no hose needed. This TH marine scupper adjusts from 1-1/2" to 3-5/8" length to handle most transoms. Used on many boats as original equipment, if yours has the TH logo (looks like an anchor) this is it!
