beamZ BSC50B - Self-Locking Hook Clamp 50 kg for 38–51 mm Tube/Truss in Black
The beamZ BSC50B is a black die-cast aluminum claw hook designed for securely mounting luminaires and accessories on tubes and truss structures . Its self-locking Quick Trigger system allows you to position the fixture against the tube, release the trigger, and the claw will lock into place while you tighten the screw, speeding up installations and reducing the risk of drops during assembly. With an opening compatible with diameters from 38 to 51 mm , an M10 threaded bolt, and a maximum load capacity of 50 kg per fixture , it offers an optimal balance between lightness and strength (only 0.23 kg ). Its horizontal hook access makes it easy to secure the fixture to the truss cable, and its ergonomic design protects your hand from the fixing screw.
