Do I need tools to install this clamp?

No tools are required for the clamp mechanism itself. It features a quick-release lever handle that snaps securely into place. You will only need a wrench to attach your light fixture to the M10 bolt.

What tube sizes does the EVT50C-AQR actually fit, and can it be used on smaller decorative truss?

The clamp fits tubes with an outer diameter between 48 mm and 51 mm (approximately 1.89 in to 2.0 in), which covers standard 50 mm truss main chords and 2-inch scaffold pipe. It will not fit smaller decorative truss tubes such as 35 mm (1.37 in) bracing found on mini truss systems like the EVT220 series. Always verify the outer diameter of your tubing before purchasing.

Is this clamp safe for overhead lifting?

Yes, provided it is used within its Working Load Limit (WLL). Always perform a visual inspection before use to ensure the lever mechanism is fully engaged and the bolt is secure. Secondary safety cables should always be used for overhead fixtures.

Is this product load-rated and certified?

Yes. The EVT50C-AQR is TUV Nord certified and rated at 220 lb (100 kg). Always follow local codes, use secondary safety cables for overhead applications, and inspect the clamp mechanism before every use.

Safety & Rigging

Inspect Every Clamp. Secure Every Fixture.

The rated capacity does not eliminate the need for proper installation, inspection, secondary attachment, load evaluation, and compliance with applicable codes and manufacturer instructions.

Do not exceed the rated capacity of 220 lb / 100 kg.

Use only on round tubing with an actual outside diameter between 48 mm and 51 mm.

Inspect the lever, collar, pivot, bolt, nut, washer, and contact surfaces before every use.

Remove the clamp from service if it is bent, cracked, worn, loose, or unable to lock fully.

Maintain sufficient clearance for the quick-release handle to rotate and lock completely.

Use an independently rated safety cable for every overhead fixture or accessory.

Installation must be performed by trained personnel in accordance with applicable requirements.
