ProBurger 2" Half Coupler w/ 1/2" bolt

Used for hanging heavy fixtures including moving lights to pipe grids and truss. Includes a 1/2" mounting bolt with locking nut. For smaller fixtures, and camera rigging, use the version with the 3/8"-16 thread. Has a slightly larger diameter than grid clamps which allows it to attach to standard 2" Truss. ProBurger couplers are constructed from a certified high tensile-strength 6061 T6 aluminum extrusion.
