This is a great rubber plug for any 1-1/4" hole! Top flange is 1-3/4" in diameter, and it has a large loop that makes putting it in & out easy! The body extends 3/4" into the hole and has 2 molded rings for an excellent seal.
Originally designed for use on the inside of the MSC3504 drain tube. Works well as a sink plug, bait well plug, or compartment marine drain plug!
