The M-PXA-1 Forkless Optical Post has a unique internal slotted base allowing it to be directly mounted to an optical table without a clamping fork. This patent-pending feature saves 3X the space of a standard pedestal while still providing positional flexibility and long-term stability. This 25.4 mm diameter aluminum post has a 25.4 mm height. Cross-drilled holes allow 5.0 mm hex wrenches to aid in tightening and loosening assembled posts.
