24 Nylon Flat Stem 3/4" Bumper Glides for Tubular Chair Bases Color:Black These fiberglass rocker spring platesTypically used on base of swivel chairs. The stem bumpers keep the round base of the patio chair from sitting directly on the ground. Most swivel bases use 6 to 8 stem bumpers per chair. Stem bumpers can be flat or coved (curved) to fit the shape of the tubular metal of the patio chair base. This flat stem bumper fits 1 4" hole and is about 1 2" long (the stem can be cut to fit length as needed). The base disc is 3 4" round and about 3 16" thick.
