The 1401-RM-2 rack mount kit is designed to work with any 4300 Series LaserSource, 5300 Series TECSource, or 6300 ComboSource, and is designed to rack mount two units side-by-side in 2U of rack space. If you will be rack mounting only a single unit, use the 1401-RM-1 which is designed for a single unit.

If you will be rack mounting other instruments directly below this rack mount kit, you will need to remove the feet from the instrument.
