Wheel the second cabinet up behind the array, remove the rear flying pin and flick out both rear flying bracket. Lower the grid
and first cabinet until you can comfortably line the second cabinet rear bracket bar with the rear bracket on the first cabinet;-
Check which hole needs to be connected from the optimisation that you did with Display 2.1 and connect the rear brackets with
the flying pins;-
Next remove the flying pin from the front stowing position on the second MLA. Raise the grid until the second cabinet is just off
the floor. As with the first cabinet and grid, the cabinet will swing forward suddenly when it leaves the floor so take care to avoid
injury. The next stage is to swing the second cabinet up to link the front rigging brackets of both boxes. To make it a little lighter
you can remove the wheelboard before you do this. With someone either side of the array, swing the cabinet up by its handle
