Product Overview

A Central Cross Junction Finished for Low-Visibility Production Environments.

The EVT290S-4WC Black creates a central intersection for four compatible 290 mm square truss runs while maintaining system geometry.

4-Way Cross Geometry
The EVT290S-4WC Black creates a central intersection for four modular square truss runs.
0.5 m Junction Section
The EVT290S-4WC Black has an overall section length of 0.5 m (1.64 ft).
Matte Black Powder Coat
The finish reduces light reflection compared to a natural aluminum surface.
Conical Connection System
The EVT290S-4WC Black uses couplers, tapered pins, and R-clips at each of its four connection points.

Common Applications

Used Where a Central Intersection Needs to Blend Into a Dark Environment.

The EVT290S-4WC Black is used where four square truss runs intersect at one central point, and the matte black finish helps the structure blend into low-light settings such as broadcast studios and black-box theaters.

01
Lighting Grids
The EVT290S-4WC Black forms central four-way intersections in overhead or freestanding lighting structures.
02
Broadcast Studios
The matte finish reduces on-camera glare from lighting fixtures aimed near the structure.
03
Black-Box Theaters
The EVT290S-4WC Black minimizes visual presence in dark performance venues.
04
Ceiling Grids
The EVT290S-4WC Black forms central intersections in suspended or supported ceiling-grid layouts.
05
Stage Frameworks
The EVT290S-4WC Black builds central stage-grid intersections with a dedicated 4-way cross.

Who It’s For

Built for Teams That Need an Intersection to Disappear Into the Background.

The EVT290S-4WC Black is designed for professional users assembling compatible modular square truss systems in venues where visual presence matters as much as structural function.

Broadcast and Studio Teams
Use the EVT290S-4WC Black for central grid intersections that must minimize glare on camera.
Event Production Companies
Use the EVT290S-4WC Black for central four-way grid and stage layouts.
Trade Show Contractors
Use the EVT290S-4WC Black in modular booth and exhibit structures requiring a low-visibility finish.
Rental Companies
Stock the EVT290S-4WC Black for inventory requiring a dedicated 4-way cross junction.
Scenic and Fabrication Shops
Use the EVT290S-4WC Black for central structural intersections and custom modular builds.
AV Integrators
Use the EVT290S-4WC Black for display, ceiling, and equipment-support structures in dark venues.

Connection Hardware

Conical Couplers, Secured with Tapered Pins and R-Clips.

The EVT290S-4WC Black uses a conical connection system. Each of its four connection points requires the same set of connection hardware.

Conical Couplers
Couplers seat between the cross junction receivers and the adjoining truss receivers.
Tapered Pins
Pins secure the couplers through the aligned receiver holes.
R-Clips
Retaining clips secure the tapered pins after installation.
All four connection points on the EVT290S-4WC Black are load-bearing.

Use only compatible connection hardware and confirm every active connection is fully seated and secured before lifting or applying load.

Connection & Compatibility

System Fit

Compatibility Fits F34, EVT290S, and all standard 290mm Square Truss systems
Main Tube Diameter 50 mm (1.96 in)
Junction Geometry 4-Way Cross

System Compatibility

Fits F34, EVT290S, and All Standard 290mm Square Truss Systems.

The EVT290S-4WC Black uses 290 mm square truss geometry, 50 mm main chords, and a matching conical connection system. Compatibility requires matching receiver spacing, coupler dimensions, and engineering data.

EVT290S
The EVT290S-4WC Black is designed for the EVT290S square aluminum truss series.
F34
The EVT290S-4WC Black is compatible with F34-format truss when receiver spacing and conical connection dimensions match.
Other 290 mm Square Systems
The EVT290S-4WC Black may fit other 290 mm square conical systems after dimensional verification.
50 mm Clamps
The main chords of the EVT290S-4WC Black accept compatible clamps designed for standard 50 mm truss tubing.

Assembly Overview

Align All Four Truss Runs Before Final Connection Inspection.

Assembly must be completed by trained personnel using compatible conical hardware and the approved structural layout.

01 — Inspect the Junction
Check chords, braces, welds, receivers, couplers, pins, and clips before use.
02 — Confirm Orientation
Position the EVT290S-4WC Black to match the approved four-way layout.
03 — Insert Couplers
Seat the conical couplers into the required receivers.
04 — Align Truss Sections
Bring each mating truss section into alignment without forcing the receivers.
05 — Install Pins and R-Clips
Fully seat every tapered pin and secure it with an R-clip.
06 — Final Inspection
Verify all four active connections and all hardware before lifting or applying load.

Safety & Engineering

Junction Capacity Depends on the Complete Engineered Structure.

The EVT290S-4WC Black does not have a standalone load rating. Allowable loading depends on connected span directions, supports, bracing, connection details, load placement, geometry, and the complete structural configuration.

Inspect all chords, braces, welds, receivers, couplers, pins, and clips before use.
Do not use components with cracks, bends, damaged welds, deformation, or excessive wear.
Confirm every tapered pin is fully seated and every R-clip is installed.
Do not place loads directly at unverified connection locations.
Balance loading across the structure and use appropriate secondary safeties where required.
Have the complete structure reviewed by a qualified engineer when required.
Assembly and use must be performed by trained personnel.
