EVT50C-BQR — Matte Black Quick-Release Pipe and Tube Clamp for 50mm Tubing

The EVT50C-BQR is a professional matte black quick-release clamp designed for speed, efficiency, and visual discretion. Whether you need a tube clamp for a truss grid or a pipe clamp for a studio lighting rail, this unit disappears into the background thanks to its durable anti-reflective black powder coat — eliminating the reflective silver surface that catches light in dark overhead environments, studio grids, and theatrical rigs where hardware visibility needs to be zero.

Function and Compatibility:

Manufactured from high-strength 6061-T6 aluminum alloy, the EVT50C-BQR features a specialized lever handle for tool-free attachment. Engineered strictly for standard 48mm to 51mm (2-inch) OD piping and truss, it is the ideal solution for theaters, concert stages, and houses of worship where hardware needs to remain invisible to the audience. The included M10 x 30mm bolt with spring lock washer connects to any standard M10 fixture yoke or accessory bracket, with all hardware finished in black to maintain finish consistency at the connection point. Rated at 500 kg safe working load and TUV Nord Certified.

Safety and Engineering Notice

Critical Rigging Guidelines:

• Load Rating: Do not exceed the rated safe working load of 500 kg (1,100 lbs).
• Inspection: Check the clamp mechanism before every use. If the lever is loose, bent, or does not lock fully closed, remove from service immediately.
• Secondary Safety: The use of safety cables is mandatory for all overhead rigging applications.
• Installation: Release the handle counterclockwise to open the collar, seat firmly on the pipe or tube, close the collar, and tighten the handle clockwise to lock.
• Finish Care: Handle with care to prevent chipping the black powder coat, which can expose the raw aluminum underneath.
• 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.

Compatibility Warning

Crucial Steps for Safe Assembly:

• Verify Diameter: Designed strictly for 48mm to 51mm (2-inch) tubing. Do not use on smaller decorative truss with 35mm (1.37-inch) tubes such as the EVT220 series.
• Handle Clearance: Ensure the quick-release handle has 360-degree clearance to rotate fully during tightening.
