This is a great boat drain plug for any 1-7/8" hole! The top flange is 2-1/4" in diameter and it has a large loop that makes putting it in & out easy! The body extends 1/2" into the hole and has 2 molded rings for an excellent seal.
Originally designed for use on the inside of the stainless steel Southco/Orcas 2" Scupper. This rubber drain stopper works well as a sink plug, baitwell plug, or compartment drain plug!
If your scupper looks like the one pictured, this is the plug you need!
