This Extra-Small Aluminum Dual-Swivel Mini Clamp from Odyssey has a black finish and features a 1"-thick aluminum-body construction. Designed for hanging fixtures from the Nexus 6 x 6" Square Truss System, the unit is compatible with pipes and tubes up to 7/8" in diameter, and thanks to its swivel action design it's an excellent tool for connecting truss tubes or any pipes or posts running perpendicular to each another.
