Cast Iron - 3-pronged Series

As with all JI Bases the “B” Series has cast iron top plates that will not bend or flex. The “B” Series 6″ wide prongs offer a heavier base plate in a smaller footprint. Simply because of the laws of physics, the “B” Series (3-prong) base will not wobble on an uneven surface because of it’s tripod shape which keeps the top parallel with the floor.
