EVT50C-ACP — Medium-Duty 2-Inch Clamp with Welded 18-Inch Post

The EVT50C-ACP is a medium-duty 2-inch clamp with a welded 18-inch x 1-inch post for 48mm to 51mm (2-inch) OD truss, tube, and pipe — a combined clamp-and-post component that mounts to a truss chord and extends a vertical post 18 inches below the attachment point for hanging drape, pipe-and-drape panels, banner poles, or other display and staging hardware that needs to drop below the truss run at a fixed offset. Rated at max load 250 kg, weighing 3.0 lbs, with a 50mm profile width collar and a 1-inch (25mm) OD welded post. A downloadable 3D file is available for CAD integration.

Function and Compatibility:

The EVT50C-ACP clamps to any 48mm to 51mm OD round tube or pipe through a wing nut collar assembly — the same opening, seating, and tightening sequence as a standard clamp, with the welded post extending downward from the clamp body once secured. The 1-inch (25mm) OD post is welded directly to the clamp body at the factory, providing a fixed 18-inch vertical drop from the truss chord to the bottom of the post. The post accepts standard 1-inch pipe-and-drape sleeves, spigot fittings, and other display hardware designed for 1-inch diameter pipe. At 3.0 lbs, the combined clamp-and-post assembly is substantial — account for the weight of the EVT50C-ACP itself when calculating total hardware load at each truss chord position. 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

• Welded 18-Inch Post: Factory-welded 1-inch (25mm) OD post extends 18 inches below the clamp collar — provides a fixed vertical drop from the truss chord for drape panels, banner poles, pipe-and-drape hardware, and display accessories.
• 1-Inch Post Diameter: The 1-inch OD post accepts standard pipe-and-drape sleeves and 1-inch spigot fittings used in drape and display hardware systems.
• 250 kg Max Load: Medium-duty collar rated at 250 kg maximum load — sufficient for drape weight, banner panels, and light display hardware on 2-inch truss and pipe.
• 50mm Profile Width: Standard-width collar seats against the full tube surface for a stable, broad-contact grip at the truss attachment point.
• 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 staging drawings and rigging plans.

Assembly Instructions

1. Release the wing nut by turning it counterclockwise to release the bolt and open the collar.
2. Place the EVT50C-ACP 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. Make sure the EVT50C-ACP 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-ACP into place.

Safety and Rigging Notice

Critical Rigging Guidelines:

• Load Rating: Do not exceed the 250 kg max load rating of the EVT50C-ACP or the rated capacity of the truss system it is installed on.
• Hardware Weight: The EVT50C-ACP itself weighs 3.0 lbs — include the clamp weight in the total hardware load calculation at each attachment point, in addition to the weight of any drape, banners, or display hardware mounted to the post.
• Post Loading: Apply loads to the post vertically within its rated capacity. Do not apply lateral forces or torque loads to the welded post joint that exceed the rated configuration.
• Inspection: The EVT50C-ACP should be fully inspected before every use, including the welded post joint for cracks, deformation, or weld defects. 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.
