EVT50C-ACC — Aluminum Medium-Duty Half-Coupler Clamp for 48mm to 51mm Tubing

The EVT50C-ACC is an aluminum medium-duty clamp with half connector for 48mm to 51mm (2-inch) OD truss, tube, and pipe — the silver-finish counterpart to the EVT50C-BCC for installations on standard aluminum truss systems where the clamp color matches the surrounding structure. Rated at max load 300 kg, at 1.34 lbs with a 50mm profile width, connecting hardware included, and a downloadable 3D file for CAD integration. The aluminum finish integrates visually with silver truss systems and provides corrosion resistance for both indoor and outdoor use.

Function and Compatibility:

The EVT50C-ACC 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 across the full 50mm profile width. All connecting hardware ships with the clamp — the bolt, washer, and wing nut are included for immediate assembly without a separate hardware order. The aluminum finish sits visually flush with the brushed aluminum surface of standard silver truss systems, and the anodized surface provides durability against moisture, UV exposure, and mild chemical contact under normal use. 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

• Aluminum Finish: Silver aluminum surface integrates with standard silver truss systems — the correct finish choice when the clamp needs to match the surrounding structure rather than disappear into a dark environment.
• 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-ACC 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-ACC 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-ACC into place.

Safety and Rigging Notice

Critical Rigging Guidelines:

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