JMAZ Lighting O-Clamp Pro Coupler

The pro coupler locks two lengths of tube together at a fixed right angle. Where the double swivel clamp is for angles that vary, this one is for the joins that should not move: a header across two verticals, a goalpost, a boom off a main run.

Both jaws are Al 6061-T6 with a 50 mm width and a 500 kg safe working load, taking 38 to 51 mm tube. Fixed geometry means fewer bolts to check on a walkthrough than an equivalent swivel.
