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 and 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 and 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 and vinyl composition tile.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.
