Product Description

Self-Locking Hook Clamp – Low Profile Matte Black (EVT50C-BIC)

The EVT50C-BIC Self-Locking Hook Clamp is a professional rigging solution designed for speed and stealth. Featuring an advanced auto-locking mechanism, this clamp allows for true one-person installation: simply hook it over the truss chord, and the internal spring lock instantly engages to hold the fixture’s weight while you tighten the wing nut.

Function & Compatibility:

Unlike standard bulky couplers, the EVT50C-BIC features a slim, low-profile design that holds lighting fixtures closer to the truss tube, eliminating unsightly gaps for a clean, high-end look. Finished in a non-reflective matte black powder coat, it blends seamlessly into dark stage environments.

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

  • One-Person Installation: The self-locking hook supports the fixture immediately, allowing you to tighten the bolt without holding the heavy light.
  • Low-Profile Design: Sits tighter to the truss than standard O-clamps for a streamlined, professional appearance.
  • High-Strength Hardware: Includes M10 (30mm) Attachment Bolt with Spring Lock Washer. Bolt Tensile Strength: 12.26 kN.
  • Stealth Finish: Durable Matte Black Powder Coat prevents glare and remains invisible to the audience.
  • 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-BIC is the preferred choice for installers who need a secure, self-locking M10 clamp that disappears into the rig.

⚠️ 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.
