EVT50C-CCB — Black Aluminum C-Clamp for 1-Inch to 2-Inch Tubing

The EVT50C-CCB is a black-finished aluminum C-clamp for 1-inch to 2-inch (25mm to 51mm) diameter truss tubes, pipes, and structural members — the dark-finish version of the EVT50C-CCA for event production, theatrical rigging, and live performance installations where the clamp needs to match a black overhead structure. Rated at 300 lbs, the single-bolt jaw accommodates any tube or pipe from 1 inch to 2 inches in diameter without sizing adjustments — place the jaw around the tube, position the clamp, and tighten clockwise. The black finish absorbs light instead of reflecting it, keeping the clamp visually integrated in dark overhead environments where a silver C-clamp would stand out against surrounding black hardware.

Function and Compatibility:

The EVT50C-CCB works through a single threaded bolt that draws the C-clamp jaws together around the tube when tightened clockwise and releases when backed off counterclockwise — no collar, no wing nut, no separate sizing hardware. The jaw accommodates any round tube or pipe in the 1-inch to 2-inch diameter range, making it adaptable across a full set of truss chord sizes, conduit diameters, and structural pipe dimensions without needing a separate clamp for each tube size. The black finish holds under stage lighting, UV, and colored wash conditions without fading or becoming reflective. 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

• Black Finish: Dark surface absorbs light and integrates with black truss systems, dark stage environments, and overhead installations where silver hardware would create visible contrast.
• 1-Inch to 2-Inch Universal Tube Range: Single C-clamp jaw fits 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 opens the jaw and clamps the tube — a 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-CCB on the truss, tube, or pipe with the jaw around the tube.
3. Make sure the EVT50C-CCB 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-CCB into place.

Safety and Rigging Notice

Critical Rigging Guidelines:

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