How to Install Middle Atlantic Caster Base, 42"D

• Prepare the rack area: clear the base of any debris and ensure the interior bottom surface is clean and free of obstacles to allow a flush seating of the recessed base inside the rack.
• Position the base: align the recessed caster base with the interior footprint of the rack so that it sits evenly on the bottom surface and the wheels have clear paths for movement.
• Insert and seat: carefully slide the base into place until it rests flush with the rack interior; check that the base is fully seated and aligned with the rack walls for optimal stability.
• Check wheel orientation: confirm that all three-inch casters are correctly oriented and rotate freely; if any wheel binds, re-seat the base or reposition slightly to regain smooth movement.
• Level and finalize: if LF leveling feet are in use, install or adjust them per the LF system guidelines to achieve a level footprint; consult page 31 of the manual for precise leveling steps. Once level, test mobility by gently rolling the rack in a controlled environment and verify stability when stopped.
