Formed felt combines an extremely durable felt tip with a tap-in base that can be used on any size or shape wooden furniture leg. Easy to install, the tap in the base is simply nailed into the bottom of the leg. Then, the peel and stick felt tip is applied to the base. Because the base is convex, the custom 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—no new nail holes! Premium felt that is made in the USA. These are the highest quality felt protectors available on the market.
