Foot caps and plug in glides protect floor coverings from scratches. Chairs and tables can be moved quietly. The caps simply push onto the steel tubes. Push in glides are pushed into the steel tube. If this is too difficult, the glides as well as the foot caps can be knocked in carefully with a rubber mallet. Ideally, this is done by using a piece of wood between rubber mallet and foot cap or push in glide. The product display always shows the external measurements of the steel tubes for which the particular product is suitable.
