EVT50C-EHEC — Black Extra Heavy-Duty 2-Inch Truss Clamp with Eyenut

The EVT50C-EHEC is a black powder coat extra heavy-duty 2-inch truss clamp with an integrated eyenut — a purpose-built rigging clamp for attaching safety cables, slings, shackles, and chain directly to 2-inch (50mm) OD truss tubing and pipe without a separate attachment point. Where a standard clamp connects fixtures through a bolt and yoke, the EVT50C-EHEC replaces the bolt with a formed eyenut loop that accepts a shackle, carabiner, or safety cable hardware directly — making it the clamp used for secondary safety attachment, load-bearing sling connection, and any overhead rigging point that needs a dedicated loop rather than a bolt interface. Built from 6061-T6 aluminum alloy, finished in black powder coat, and TUV Nord Certified.

Function and Compatibility:

The EVT50C-EHEC clamps to any 48mm to 51mm OD round tube or pipe through the standard wing nut collar assembly — the same opening, seating, and tightening sequence as every other clamp in the EVT50C family. What sets it apart is the attachment interface: instead of a threaded bolt hole for a fixture yoke, the clamp body carries an integrated eyenut — a formed loop sized to accept standard rigging hardware including shackles, snap hooks, carabiners, and safety cable ferruled ends. The black powder coat finish keeps the clamp visually integrated with dark overhead rigs and eliminates the reflective silver surface that catches light in stage environments. 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

• Integrated Eyenut Attachment: A formed eyenut loop replaces the standard attachment bolt — provides a dedicated rigging point for shackles, carabiners, slings, and safety cable hardware directly on the truss tube without a separate anchor point.
• Black Powder Coat Finish: Factory-applied black powder coat absorbs light and integrates with black truss systems and dark stage environments — no reflective silver surface at the rigging attachment point.
• Extra Heavy-Duty Construction: Built from 6061-T6 aluminum alloy for demanding overhead rigging applications where the eyenut carries dead load or secondary safety loads.
• 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.
• TUV Nord Certified: Independently tested and certified — not manufacturer self-certification.
• Wing Nut Closure: Tool-free collar tightening — open, seat, and lock without wrenches or hex keys.

Assembly Instructions

1. Release the wing nut by turning it counterclockwise to release the bolt and open the collar.
2. Place the EVT50C-EHEC 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-EHEC 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-EHEC into place.

Safety and Rigging Notice

Critical Rigging Guidelines:

• Load Rating: Do not exceed the rated load capacity of the EVT50C-EHEC or the truss system it is installed on. Contact Evolve Truss for load documentation before use in structural overhead applications.
• Eyenut Loading: The eyenut is designed for in-line axial loading through the eye. Do not apply side loads or angular loads to the eyenut that fall outside the rated configuration.
• Inspection: The EVT50C-EHEC should be fully inspected before every use, including the eyenut loop for deformation, cracking, or wear. 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.
