We offer different sets of castors as accessories for some of our waste baskets. A set basically consists of four castors. The castors are of different sizes, made of metal or plastic, and they can be inserted into the bottom of the waste paper baskets. This makes it easier to empty large or bulky wastepaper baskets or entire wastepaper basket systems in particular, or to use them in different places. The castors make pushing and transporting much easier.
