1.5 SB218 RIGGING SYSTEM
The SB218 BUMPSUB rigging system consists of one steel bar, four 22 mm shackles and two chains
incorporating Aeroquip double stud fittings. The Aeroquip fittings are connected to the flytrack
sections located on each side of the SB218 (two per loudspeaker on each side = 4 total per SB218).
The BUMPSUB flying bar is rated for up to 8 subwoofer enclosures at a 5:1 safety factor.
Note: It is recommended to preattach shackles and fittings to the chains prior to flying. Lay the chain out
flat and remove any twists. Shackles and double stud fittings are then attached every 13 chain links, i.e.,
with a separation of 11 open chain links between each shackle as shown in the figure below.
