EVT50C-HDC — Heavy-Duty 2-Inch Clamp with M10 Bolt for 48mm to 51mm Tubing

The EVT50C-HDC is a heavy-duty silver anodized clamp for 48mm to 51mm (2-inch) OD truss, tube, and pipe — rated at 500 kg safe working load with 3,990.3 kN tensile strength for fastening lighting fixtures and rigging accessories in place on standard 2-inch truss and pipe. The standard M10 x 35mm metric attachment bolt with spring lock washer connects directly to the M10 fixture yokes used across the majority of professional lighting and audio hardware. At 0.52 kg, built from 6061-T6 aluminum alloy with an anodized silver finish and TUV Certified — the silver-finish counterpart to the EVT50C-BHC for installations where the clamp color matches a silver truss system.

Function and Compatibility:

The EVT50C-HDC clamps to any 48mm to 51mm OD round tube or pipe through a wing nut collar assembly. The collar opens counterclockwise, seats onto the tube, closes, and locks with the wing nut tightened clockwise. The M10 x 35mm bolt with spring lock washer threads into any fixture yoke or accessory bracket with a standard M10 mounting slot — the metric standard used across moving heads, LED pars, wash fixtures, and most professional rigging accessories. The spring lock washer maintains bolt tension under vibration and thermal cycling without re-tightening between performances. The silver anodized finish integrates with standard aluminum truss systems and provides corrosion resistance for both indoor and outdoor use. Compatible with EVT290S, EVT290I, F34 series truss main chords, and standard Schedule 40 aluminum pipe in the 48mm to 51mm outer diameter range.

Assembly Instructions

1. Release the wing nut by turning it counterclockwise to release the bolt and open the collar.
2. Place the EVT50C-HDC on the truss, tube, or pipe and close the collar.
3. Put the bolt back in place with the washer and wing nut above the collar.
4. Ensure the EVT50C-HDC is located in its proper place on the truss, tube, or pipe before tightening the wing nut.
5. Turn the wing nut clockwise to tighten and secure the EVT50C-HDC into place.

Safety and Rigging Notice

Critical Rigging Guidelines:

• Load Rating: Do not exceed the 500 kg safe working load of the EVT50C-HDC or the rated capacity of the truss system it is installed on.
• Inspection: The EVT50C-HDC 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.
