This is a great rubber boat scupper plug for any 1-7/8" hole! Top flange is 2-1/4" 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 Southco/Orcas 2" Scupper. 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!
