The ball base has a hole pattern to fit most standard T-slot aluminum extrusions. The through hole can be used for routing wires, cables, or small hoses. There is an exit groove out the side of the base for cables, hose, and wires. This ball base mounts to Imperial (AFSB) plates without XS in the part number and to the Imperial knuckles (AFSB-2, AFSB-290, and AFSB-2-2XS coupler).
