Single Stud Tandem track fittings are designed to couple multiple loudspeakers and other single Anchor Plate and L-track equipped objects together into vertical columns. Tandem fittings make assembling small clusters for temporary installations fast and secure. Its ring allows objects to be secured with a wide range of readily available coupling devices such as, carabiners, quick links and shackles. This design does not offer a redundant locking feature that is sometimes required in overhead applications. If the cabinet being suspended is not already equipped with L-track or Anchor Plates, be sure to select the aluminum TK-002-02 Anchor Plate and stainless TK-100-IB internal brace for outdoor applications and CB-375-02 or CB-M10-02 corner braces for indoor application.
