Locking a rigging bar (WIFORIG, SB18MRIG or WIFOLIFT)

Coupling bars and SB18m
For SB18m/SB18m or SB18m/WIFOBUMP attachment, only use the long SB18MRIG bars stored on the
SB18m subwoofers. The shorter WIFORIG bars cannot ensure the mechanical safety of these connections.

1 WIFOLIFT for 2 or 4 ARCS
RIGGING: Slide the bar into adjacent rigging rails from the front of the array.
STORAGE: Engage the bar into both storage pins.
Secure the bar with the locking tab.
a. Accurately position the bar by pushing it into place.
