This optional two-piece spacer can be used to create more room for through-the-mount cabling by placing them between the top of the Paramount MYT declination axis and the Versa-Plate. You will find this spacer particularly useful when the Versa-Plate is mounted in the wide orientation (see the Paramount User Guide for details). It may also be used in the standard orientation to allow more "clearance" for instrument cabling.
