MG-MINA/LINA/750-LFC GRID ASSEMBLY GUIDE

750-LFC cabinets equipped with the MRK-750 rigging kit provide for more secure transport as the bottom cabinet can be
linked and pinned to the caster frame. The three cabinets can be linked and pinned together as well.

TIP:

Durable nylon pullover covers, sized for stacks of 2 units or 3 units, are available to protect 750-LFC cabi-

nets during transport. Special wraparound covers are also available to accommodate stacks with grids on top.

TIP:

The MG-MINA/LINA/750-LFC grid can travel installed on top of 750-LFC stacks on the MCF-750 caster

frame.
