Product Description

Quick Release Self-Locking Hook Clamp – 50mm (2″) (EVT50C-AHC)

The EVT50C-AHC is a professional Quick Release Self-Locking Hook Clamp engineered for precision and speed. Featuring a pre-installed M10 Attachment Bolt with a spring lock washer, this coupler is ready to mount to standard lighting yokes right out of the box. Its natural aluminum finish allows it to blend seamlessly with standard truss systems, making it the ideal choice for industrial, architectural, and stage applications.

Function & Compatibility:

Designed for efficiency, the EVT50C-AHC features an advanced auto-locking mechanism that enables true one-person installation. Simply hook the clamp over the truss chord, and the internal spring lock instantly engages to hold the fixture’s weight while you tighten the wing nut. Its slim, low-profile design holds fixtures tighter to the tube than standard clamps, reducing gaps for a clean, precision-rigged appearance.

Truss Compatibility: Fits F34, EVT290S, and all standard 290mm Conical Truss systems, as well as EVT12S and other standard 12-inch plated truss systems using bolt connections.

Key Features

• Quick Release Action: The self-locking hook supports the fixture immediately, allowing you to tighten the bolt without holding the heavy light.
• One-Person Installation: Designed to snap onto the truss and hold itself in place, significantly reducing setup time.
• High-Strength Hardware: Includes M10 (30mm) Attachment Bolt with Spring Lock Washer. Bolt Tensile Strength: 12.26 kN.
• Low-Profile Design: Sits tighter to the truss than standard O-clamps for a streamlined appearance.
• Tube Compatibility: Compatible with standard 48mm – 50mm (1.9″ – 2.0″) truss tubes.
• Load Capacity: Rated for a Safe Working Load of 150 kg (330 lbs).
• Certified Safety: TUV Nord Certified and constructed from high-strength 6061-T6 Aluminum Alloy.

Designed by Evolve Truss, the EVT50C-AHC combines industrial strength with the ease of a quick release self-locking hook.

⚠️ Safety & Engineering Notice

❗ Critical Rigging Guidelines:

• Load Rating: Do not exceed the rated capacity (330 lbs / 150 kg).
• Inspection: Check the spring-loaded locking mechanism before every use.
• Secondary Safety: The use of safety cables is mandatory for all overhead rigging.
• Installation: Hook the clamp over the tube, listen for the “click” of the self-lock, and firmly tighten the wing nut.

⚠️ Compatibility Warning

Crucial Steps for Safe Assembly:

• Verify Diameter: Designed strictly for 48mm-50mm tubing. DO NOT USE on smaller decorative truss with 35mm (1.37″) tubes (such as EVT220 series).
• Check Clearance: Ensure the hook body has sufficient clearance around bracing to seat fully onto the chord.
