Quickly assemble loudspeaker columns and clusters together using this tandem design, especially for live performance venue set up. Tandem fittings couple multiple loudspeakers and other track equipped objects together into vertical columns. This assembly comes with swivel rings to limit side loading and for ease in coupling to carabiners, quick links and shackles. This design offers a redundant locking feature that is sometimes required in overhead applications. If the cabinet being suspended is not already equipped with L-track, be sure to select one of the compatible track and internal brace kits from the internal portion of this rigging hardware section.
