EVT35C-BJQ — Black Quick-Release Aluminum Truss Clamp for 35mm Tubing

The EVT35C-BJQ is a light-duty black quick-release aluminum clamp for 1.37-inch (35mm) OD tubing, truss, and pipe — combining the speed of a lever handle with a dark finish that integrates into black truss systems and stage environments where a silver clamp would break the visual. The quick-release lever opens and locks the collar with a half-turn, letting crews hang, adjust, and strike fixtures on narrow-chord truss without stopping to hand-spin a wing nut at each position. Built from 6061-T6 aluminum alloy, rated at max shear load 30 kg with 11.64 kN tensile strength, and TUV Nord Certified. Ships with an M10 x 30mm bolt and spring lock washer for immediate fixture connection.

Function and Compatibility:

The EVT35C-BJQ mounts to any 35mm OD round tube or pipe through a quick-release lever collar. The lever releases counterclockwise to open the collar, the collar seats onto the tube, and the lever closes and tightens clockwise — a complete mount cycle in seconds without tools. The included M10 x 30mm bolt with spring lock washer connects to any fixture yoke or accessory bracket with a standard M10 mounting slot, with the spring lock washer maintaining bolt tension under vibration independent of the lever mechanism. The black finish absorbs light under every stage, UV, and overhead lighting condition — keeping the clamp visually invisible in dark overhead grids where the silver version would catch light and create contrast against the surrounding black structure. Compatible with EVT220S and EVT220T series truss main chords, standard 35mm aluminum pipe, and any round tube in the 35mm outer diameter range.

Key Features

• Quick-Release Lever Handle: Half-turn lever opens and locks the collar without wing nuts or tools — fast mounting, fast repositioning, fast strike across every clamp position in the rig.
• Black Finish: Dark surface absorbs light and integrates with black truss systems, dark stage environments, and any overhead installation where silver hardware creates an unwanted visual break.
• 35mm Tube Fit: Designed for 1.37-inch (35mm) OD tubing — compatible with EVT220S, EVT220T, and other light-duty truss systems with 35mm main chords.
• Light-Duty Load Rating: Rated at max shear load 30 kg and tensile strength 11.64 kN — suited for LED pars, small effect fixtures, and light accessory hardware on narrow-chord truss.
• M10 Attachment Bolt Included: Ships with M10 x 30mm bolt and spring lock washer — connects to any fixture yoke or accessory bracket with a standard M10 mounting slot.
• 6061-T6 Aluminum Body: High-strength structural aluminum — lightweight for quantity use without adding significant load to the truss system.
• S45C Carbon Steel Hardware: High-strength S45C carbon steel fasteners for reliable long-term clamping performance.
• TUV Nord Certified: Independently tested and certified load ratings.

Assembly Instructions

1. Release the quick-release handle by turning it counterclockwise to open the collar.
2. Place the EVT35C-BJQ on the truss, tube, or pipe and close the collar.
3. Put the quick-release handle back into place with the washer above the collar.
4. Make sure the EVT35C-BJQ is set in its proper place on the truss, tube, or pipe before tightening the handle.
5. Turn the quick-release handle clockwise to tighten and secure the EVT35C-BJQ into place.

Safety and Rigging Notice

Critical Rigging Guidelines:

• Load Rating: Do not exceed the rated load capacity of the EVT35C-BJQ or the truss system it is installed on.
• Inspection: The EVT35C-BJQ 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.
