EVT50C-CCN — Narrow Light-Duty Half-Coupler Clamp for 48mm to 51mm Tubing
The EVT50C-CCN is a narrow light-duty clamp with half coupler for 48mm to 51mm (2-inch) OD truss, tube, and pipe — engineered specifically to fit between the diagonal cross bracing of truss where a standard-width clamp body would interfere with the brace members. At a profile width of 30mm and weighing just 0.98 lbs, the narrow body clears the diagonal bracing geometry of standard square truss systems, making it the clamp for single-tube applications and tight mid-span positions that wider clamps physically cannot occupy. Rated at max load 200 kg, available with a downloadable 3D file for CAD integration.
Function and Compatibility:
The EVT50C-CCN clamps to any 48mm to 51mm OD round tube or pipe through a wing nut collar assembly. The half-coupler body provides a stable seating profile against the tube, and the narrow 30mm profile width is the critical dimension — at this width, the clamp body clears the diagonal cross bracing members of standard 290mm square truss when positioned at mid-span between the brace attachment points, where a standard-width clamp would contact the bracing and prevent proper seating or rotation. This makes the EVT50C-CCN the correct clamp for positions along a single tube or truss chord in the areas where diagonal brace geometry limits available clearance. Compatible with EVT290S, EVT290I, F34 series truss main chords, and standard Schedule 40 aluminum pipe in the 48mm to 51mm outer diameter range.
Key Features
- Fits Between Diagonal Cross Bracing: The 30mm narrow profile is specifically sized to clear the diagonal brace members of standard square truss systems — the correct clamp for mid-span and single-tube positions where standard-width clamps cannot seat properly.
- 30mm Profile Width: Narrow body keeps hardware clearance requirements minimal in tight truss geometries and high-density rig configurations along a single tube run.
- Half-Coupler Seating Profile: Body seats closely against the tube surface for a stable, low-profile grip.
- Light-Duty, 200 kg Max Load: Rated at 200 kg maximum load for light fixture, accessory, and cable management mounting on narrow-clearance truss positions.
- Lightweight at 0.98 lbs: Compact and lightweight for quantity use without adding significant load to the truss system.
- 48mm to 51mm Tube Fit: Fits standard 48mm to 51mm (2-inch) OD tubing — compatible with F34 truss, EVT290S, EVT290I main chords, and Schedule 40 aluminum pipe.
- S45C Carbon Steel Hardware: High-strength S45C carbon steel fasteners for reliable long-term clamping performance.
- Wing Nut Closure: Tool-free collar tightening — open, seat, and lock without wrenches or hex keys.
- 3D File Available: STEP and DWG files available for download for CAD integration into structural drawings and rigging plans.
Assembly Instructions
- Release the wing nut by turning it counterclockwise to release the bolt and open the collar.
- Place the EVT50C-CCN on the truss, tube, or pipe and close the collar.
- Put the bolt back in place with the washer and wing nut above the collar.
- Make sure the EVT50C-CCN is located in its proper place on the truss, tube, or pipe before tightening the wing nut.
- Turn the wing nut clockwise to tighten and secure the EVT50C-CCN into place.
Safety and Rigging Notice
Critical Rigging Guidelines:
- Load Rating: Do not exceed the max load rating of the EVT50C-CCN or the rated capacity of the truss system it is installed on.
- Verify Clearance: Confirm that the clamp body clears all diagonal brace members at the intended installation position before tightening. Do not force the clamp into a position where the body contacts the truss bracing.
- Inspection: The EVT50C-CCN 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.
