Replacement Rubber Stoppers for Underwater Plinth

Intended for the two legs of the Underwater Plinth that rest against the inside of the pool wall, under the water.
Each black stopper is inserted into each steel tube to seal it. Once inserted, the white stoppers are then fitted over the black ones to create a non-skid and non-marking point where the frame rests against the inside pool wall.
Sold in set of 4 stoppers.
