EVT50C-BTC — Black Heavy-Duty Hook-Style 2-Inch Clamp

The EVT50C-BTC is a black powder coat heavy-duty hook-style clamp for 2-inch (50mm) OD truss, tube, and pipe — a hook-body fixture clamp rated at max shear load 50 kg with 11.27 kN tensile strength for mounting lighting fixtures and accessories on standard 2-inch truss and pipe in installations where the clamp needs to match a dark overhead structure. The hook body profile seats over the truss chord from above, and the M10 x 30mm bolt with spring lock washer connects 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-BTC uses a hook body that seats over the truss tube from above rather than wrapping fully around it — the hook profile positions the fixture close to the tube with a compact footprint, and the M10 x 30mm bolt with spring lock washer threads into the fixture yoke to lock the assembly. The spring lock washer maintains 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 invisible in dark overhead rigs where silver hardware would create visible contrast. Compatible with EVT290S, EVT290I, F34 series truss main chords, and standard Schedule 40 aluminum pipe in the standard 2-inch outer diameter range.

Key Features

• Black Powder Coat Finish: Factory-applied black powder coat absorbs light and integrates with black truss systems and dark stage environments.
• Hook-Style Body: Hook profile seats over the truss chord from above for a compact, close-fitting fixture mount — different from collar-style clamps that wrap fully around the tube.
• Max Shear Load 50 kg: Heavy-duty rating at 50 kg max shear load and 11.27 kN tensile strength, TUV Nord Certified — for lighting fixtures, small speakers, and accessories on 2-inch truss and pipe.
• M10 Attachment Bolt Included: Ships with M10 x 30mm bolt and spring lock washer — connects to any standard M10 fixture yoke or mounting bracket.
• 6061-T6 Aluminum Body: High-strength structural aluminum construction.
• S45C Carbon Steel Hardware: High-strength S45C carbon steel fasteners for reliable long-term clamping performance.
• TUV Nord Certified: Independently tested and certified load ratings.

Safety and Rigging Notice

Critical Rigging Guidelines:

• Load Rating: Do not exceed the max shear load rating of the EVT50C-BTC or the rated capacity of the truss system it is installed on.
• Inspection: The EVT50C-BTC should be fully inspected before every use. In the occurrence of any damage or defect, the clamp should not be used.
• Secondary Safety: The use of safety cables is recommended for maximum security on all overhead applications.
• Professional Review: The purchase of this product does not authorize or approve a specific installation or use. A licensed professional engineer shall review all structures, lighting plots, or other clamp uses.
