EVT50C-BNC — Black Medium-Duty 2-Inch Truss Clamp

The EVT50C-BNC is a black powder coat medium-duty 2-inch truss clamp for standard 48mm to 51mm (2-inch) OD truss, tube, and pipe — a straightforward collar clamp rated at max shear load 40 kg with 23.96 kN tensile strength for mounting lighting fixtures and accessories in installations where the clamp color needs to match a dark overhead structure. The M10 x 30mm bolt with spring lock washer connects directly to standard M10 fixture yokes and mounting brackets. Built from 6061-T6 aluminum alloy, finished in black powder coat, and TUV Nord Certified.

Function and Compatibility:

The EVT50C-BNC clamps to any 48mm to 51mm OD round tube or pipe through a wing nut collar assembly. The collar opens counterclockwise, seats onto the tube, closes, and locks with the wing nut tightened clockwise. The included M10 x 30mm bolt with spring lock washer threads into any standard M10 fixture yoke or accessory bracket, with the spring lock washer maintaining bolt tension under vibration and thermal cycling without re-tightening. The black powder coat finish absorbs light under stage, UV, and overhead lighting conditions, keeping the clamp integrated with dark truss systems where silver hardware would stand out. Compatible with EVT290S, EVT290I, F34 series truss main chords, and standard Schedule 40 aluminum pipe in the 48mm to 51mm outer diameter range.
