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

The EVT35C-AJQ is a light-duty quick-release aluminum clamp for 1.37-inch (35mm) OD tubing, truss, and pipe — the faster-mounting alternative to wing nut clamps for production crews who need to hang, adjust, and strike lighting fixtures and accessories on narrow-chord truss systems without slowing down for hand-tightening at every position. The quick-release lever handle opens and locks the collar with a half-turn — no wing nut to spin, no bolt to pull, no tool required. Mount a fixture, close the lever, move to the next 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-AJQ mounts to any 35mm OD round tube or pipe through a quick-release lever collar mechanism. The lever handle releases counterclockwise to open the collar, the collar seats onto the tube, and the lever closes and tightens clockwise to lock the clamp in place — a full mount cycle in seconds without tools or loose hardware. The included M10 x 30mm bolt with spring lock washer connects to any fixture yoke or accessory bracket with a standard M10 mounting slot. The spring lock washer maintains bolt tension under vibration, keeping the fixture connection secure independently of the lever mechanism. Compatible with EVT220S and EVT220T series truss main chords, standard 35mm aluminum pipe, and any round tube in the 35mm outer diameter range used in event production, exhibition builds, and retail display installations.

Key Features

Assembly Instructions

1. Release the quick-release handle by turning it counterclockwise to open the collar.
2. Place the EVT35C-AJQ 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-AJQ 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-AJQ into place.

Safety and Rigging Notice
