Forkless Optical Post, Aluminum, 4.0 in. Height, 8-32

The PXA-4 Forkless Optical Mounting 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 1 inch (25.4 mm) diameter aluminum post has a 4 inch (101.6 mm) height. Each post is marked with an index groove every 1 in. (25.4 mm) for a quick height reference. Cross-drilled holes allow 3/16 inch hex wrenches to aid in tightening and loosening assembled posts.
