The B-2SA, provides coarse tool-free x-y positioning through the novel use of a hex head bolt in a counterbored slot. Simply twist the post holder to loosen, slide to the desired position, and then twist back to tighten - all without removing the base from the table! The base also has another bottom-side counterbored through hole to allow attachment of post holders like the VPH-3 or posts like the PS-3T. The base rests on relieved pads to provide long term stability.
