EVT50C-BCC — Black Medium-Duty Half-Coupler Clamp for 48mm to 51mm Tubing

The EVT50C-BCC is a black medium-duty clamp with half connector for 48mm to 51mm (2-inch) OD truss, tube, and pipe — a standard-width half-coupler clamp rated at max load 300 kg for fixture mounting, accessory hanging, and light rigging applications in installations where the clamp color needs to match a dark overhead structure. At 1.34 lbs with a 50mm profile width, connecting hardware included, and a downloadable 3D file for CAD integration. The black finish absorbs light under every stage and overhead lighting condition, keeping the clamp integrated with dark truss systems where a silver clamp would create visible contrast.

Function and Compatibility:

The EVT50C-BCC clamps to any 48mm to 51mm OD round tube or pipe through a wing nut collar assembly. The half-coupler body seats against the tube surface for a stable, close-fitting grip, and the wing nut tightens clockwise to lock the clamp in place. All connecting hardware is included — the bolt, washer, and wing nut ship with the clamp for immediate assembly without a separate hardware order. The 50mm profile width is the standard full-width half-coupler dimension, providing broad contact with the tube surface for maximum stability under load. The black finish holds under stage lighting, UV, and colored wash conditions. Compatible with EVT290S, EVT290I, F34 series truss main chords, and standard Schedule 40 aluminum pipe in the 48mm to 51mm outer diameter range.

Key Features

• Black Finish: Dark surface absorbs light and integrates with black truss systems and dark overhead environments where silver hardware would create a visible contrast.
• Half-Coupler Seating Profile: Standard 50mm profile width seats closely against the tube surface for a stable, broad-contact grip under medium-duty loads.
• Max Load 300 kg: Medium-duty rating for fixture mounting, accessory hanging, and light rigging applications on 2-inch truss and pipe.
• Connecting Hardware Included: Ships with all necessary connecting hardware — bolt, washer, and wing nut — ready for immediate assembly.
• Lightweight at 1.34 lbs: Manageable weight for quantity deployment across a full rig without adding significant load to the truss system.
• 48mm to 51mm Tube Fit: Fits standard 48mm to 51mm (2-inch) OD tubing — compatible with F34 truss, EVT290S, EVT290I main chords, and Schedule 40 aluminum pipe.
• S45C Carbon Steel Hardware: High-strength S45C carbon steel fasteners for reliable long-term clamping performance.
• Wing Nut Closure: Tool-free collar tightening — open, seat, and lock without wrenches or hex keys.
• 3D File Available: STEP and DWG files available for download for CAD integration into structural drawings and rigging plans.

Assembly Instructions

1. Release the wing nut by turning it counterclockwise to release the bolt and open the collar.
2. Place the EVT50C-BCC on the truss, tube, or pipe and close the collar.
3. Put the bolt back in place with the washer and wing nut above the collar.
4. Make sure the EVT50C-BCC is located in its proper place on the truss, tube, or pipe before tightening the wing nut.
5. Turn the wing nut clockwise to tighten and secure the EVT50C-BCC into place.

Safety and Rigging Notice

Critical Rigging Guidelines:

• Load Rating: Do not exceed the max load rating of the EVT50C-BCC or the rated capacity of the truss system it is installed on.
• Inspection: The EVT50C-BCC 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.
