Newport MKS Double-Slotted Base, Stainless Steel, XY, 1.0 in. Range B-2SA

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. This product is also available in 10-piece saving pack .
