These things are great! Nylon caps with felt pads for the feet of your classroom chairs. They are silent and they prevent those streaks, scuffs and worn areas on the floor. Forget about those ridiculous looking tennis balls stuck on chair legs. When I got these, my concern was that the felt base would not last and I would have to replace them too often. It is safe to say that I was mistaken….kind of amazingly mistaken. I installed these around 12 years ago and the original ones are still intact. I have used a couple dozen spares to replace ones that have been lost. Pretty impressive considering all the grime that students track in every year.
I bought them from Shiffler Equipment. These days 100 caps costs around $30…well worth the money in my opinion. They also sell a tool to help remove them when necessary. The manufacturer suggested a dab of glue when installing to help them stay in place. I understand the latest model of the caps is deeper and may not need the adhesive.
