EVT50C-ATC — Heavy-Duty Hook-Style 2-Inch Clamp with T-Handle

The EVT50C-ATC is a heavy-duty hook-style clamp for 2-inch (50mm) OD truss, tube, and pipe — the T-handle closure version of the hook-style clamp family for installations where a large T-handle provides faster hand-tightening leverage than a standard wing nut. Rated at max shear load 50 kg with 11.27 kN tensile strength, the M10 x 30mm bolt with spring lock washer connects to standard M10 fixture yokes and mounting brackets. Built from 6061-T6 aluminum alloy and TUV Nord Certified, in a natural aluminum finish that integrates with standard silver truss systems.

Function and Compatibility:

The EVT50C-ATC uses a hook body that seats over the truss tube from above, and the large T-handle replaces the wing nut for collar closure — the T-bar grip provides more hand-tightening leverage than a standard wing nut, making it faster to achieve a firm lock without tools across multiple clamp positions on a rig. The M10 x 30mm bolt with spring lock washer connects to any standard M10 fixture yoke or mounting bracket, with the spring lock washer maintaining bolt tension under vibration and thermal cycling. The natural aluminum finish sits visually consistent with standard silver truss systems. Compatible with EVT290S, EVT290I, F34 series truss main chords, and standard Schedule 40 aluminum pipe in the standard 2-inch outer diameter range.

Key Features

• Large T-Handle Closure: The T-bar handle provides more hand-tightening leverage than a standard wing nut — faster to lock firmly without tools across multiple clamp positions on a rig.
• Hook-Style Body: Hook profile seats over the truss chord from above for a compact, close-fitting fixture mount.
• Natural Aluminum Finish: Silver aluminum surface integrates with standard silver truss systems.
• Max Shear Load 50 kg: Rated at 50 kg max shear load and 11.27 kN tensile strength, TUV Nord Certified — for lighting fixtures and accessories on 2-inch truss and pipe.
• M10 Attachment Bolt Included: Ships with M10 x 30mm bolt and spring lock washer — connects to any standard M10 fixture yoke or mounting bracket.
• 6061-T6 Aluminum Body: High-strength structural aluminum construction.
• S45C Carbon Steel Hardware: High-strength S45C carbon steel fasteners for reliable long-term clamping performance.
• TUV Nord Certified: Independently tested and certified load ratings.

Assembly Instructions

1. Release the large T-handle by turning it counterclockwise to release the bolt and open the collar.
2. Place the EVT50C-ATC on the truss, tube, or pipe and close the collar.
3. Place the large T-handle back into position with the washer and T-handle above the collar.
4. Make sure the EVT50C-ATC is set in its proper place on the truss, tube, or pipe before tightening the T-handle.
5. Turn the large T-handle clockwise to tighten and secure the EVT50C-ATC into place.

Safety and Rigging Notice

Critical Rigging Guidelines:

• Load Rating: Do not exceed the max shear load rating of the EVT50C-ATC or the rated capacity of the truss system it is installed on.
• Inspection: The EVT50C-ATC should be fully inspected before every use. 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.
