Bases Bases are round metal plates, which are used to provide support for wire bar chairs on soft surfaces, which may cause the wire spacer to sink into the ground. Bases are available in either 154mm diameter to suit wire bar chairs up to 140mm in height. Bases 224mm suits wire bar chairs to 200mm in height.
