The 1402C-RM rack mount kit is designed to work with any 485, 585, 586, or 685 Paks. When racking Paks on their sides, up to 5 units can be racked into a 3U space. When racking on their bases, up to 3 units can be racked into a 2U space. When using 586s, the tray only supports three units lying flat.
If you will be mounting instruments on their bases, the adhesive feet will need to be removed from the units.
