Blizzard Lighting Klamp-C Cast Aluminum Wrap-Around Truss Clamp

The Klamp-C is a single-piece cast aluminum clamp that wraps fully around 2 inch truss tube rather than hooking over it, which is what you want when a fixture is going to be flown over an audience. Blizzard rates it at a 220 lb working load limit against a 1,350 lb proof load, a 6:1 safety factor.

The body is 6.5 x 3.8 x 1.3 inches and weighs half a pound, so it adds very little to the hang, and it closes on an M10 bolt. Fixture attachment is the standard clamp bolt through the yoke. Blizzard covers it with a limited lifetime warranty.
