PLH290 is a simple extruded aluminium coupler designed for truss system connections. It features a built-in M10 x 50 mm stainless steel bolt with associated fastening nuts for secure assembly. The coupler has an internal diameter of 50.8 mm, engineered to accommodate tubes ranging from 48 mm to 51 mm in outer diameter. With a maximum load capacity of 100 kg, this component provides reliable structural integrity for temporary rigging applications in event production environments. The coupler's aluminium construction ensures lightweight performance while maintaining sufficient strength for standard truss connection requirements in event setups.
