For simpler protection for your floors, Nail-in Chair Glides combine a dynamic felt tip with a tap-in base that can be used on any wooden chair leg – no matter the shape or size. They protect your floor surfaces from scratches, reduce noise when moving furniture & extend the life of the original furniture glide. Durable glides are easy to install. Simply nail into the bottom of the hair leg, peel the release liner & place the felt tip on the base. With a convex base, the molded felt tip adheres much better than a traditional flat felt pad. If the felt wears out, you simply replace it with a new felt pad (not included) so no new nail holes. Glides are recommended for all hard floor surfaces, wood, ceramic tile, finished concrete & vinyl composition tile.
