EVT50C-CCA — Aluminum C-Clamp for 1-Inch to 2-Inch Tubing, 300 lb Capacity

The EVT50C-CCA is a durable aluminum C-clamp for 1-inch to 2-inch (25mm to 51mm) diameter truss tubes, pipes, and structural members — a versatile mounting solution rated at 300 lbs for event production, theatrical rigging, and live performance applications where a single bolt adjustment accommodates a wide range of tube diameters without swapping clamp sizes. Unlike collar-style clamps that are sized to a specific tube diameter, the C-clamp jaw opens and closes through a single bolt that both adjusts the jaw gap and clamps the tube — one component, one adjustment, one tube diameter range covering the full span from 1-inch pipe to standard 2-inch truss.

Function and Compatibility:

The EVT50C-CCA works through a threaded bolt that draws the C-clamp jaws together around the tube when tightened clockwise, and releases the tube when backed off counterclockwise — no separate collar, no wing nut, no bolt-and-collar assembly. Place the open jaw around the tube, position the clamp at the correct location, and tighten the bolt clockwise until the jaws grip the tube securely. The single-bolt design adapts to any tube or pipe in the 1-inch to 2-inch diameter range without adjustment rings or separate sizing hardware. Compatible with round tubing, pipe, structural members, and truss chords in the 25mm to 51mm outer diameter range used in event production, theatrical rigging, film sets, and light-duty industrial overhead applications.

Key Features

• 1-Inch to 2-Inch Universal Tube Range: Single C-clamp design accommodates any tube or pipe from 1 inch to 2 inches (25mm to 51mm) in diameter — one clamp covers the full range without separate sizing.
• 300 lb Rated Capacity: Load-rated at 300 lbs for event production, theatrical, and live performance mounting applications.
• Single-Bolt Adjustment: One bolt both adjusts the jaw gap and clamps the tube — simpler installation sequence than collar-style clamps with separate wing nut and bolt hardware.
• Versatile Application: Compatible with truss tubes, conduit, structural pipe, and any round member in the 1-inch to 2-inch diameter range used in event, theatrical, and production environments.
• S45C Carbon Steel Hardware: High-strength S45C carbon steel fasteners for reliable long-term clamping performance.

Assembly Instructions

1. Release the bolt by turning it counterclockwise to open the jaw.
2. Place the EVT50C-CCA on the truss, tube, or pipe with the jaw around the tube.
3. Make sure the EVT50C-CCA is located in its proper place on the truss, tube, or pipe before tightening the bolt.
4. Turn the bolt clockwise to tighten and secure the EVT50C-CCA into place.

Safety and Rigging Notice

Critical Rigging Guidelines:

• Load Rating: Do not exceed the 300 lb rated capacity of the EVT50C-CCA or the load capacity of the truss or pipe system it is installed on.
• Inspection: The EVT50C-CCA 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.
