Product Overview

A Central Junction That Joins Four Truss Directions at a Single Cross Point.

The EVT290S-4WC creates a four-direction cross intersection while maintaining the geometry of compatible 290 mm square conical truss.

4-Way Cross Geometry
The EVT290S-4WC creates a fixed four-direction intersection for modular square truss layouts.
0.5 m Junction Section
The EVT290S-4WC has an overall section length of 0.5 m (1.64 ft).
Brushed Aluminum Finish
The finish matches natural-finish truss systems used in stage, exhibit, and ceiling-grid environments.
Conical Connection System
The EVT290S-4WC uses couplers, tapered pins, and R-clips at each of its four connection points.

Common Applications

Build Four-Directional Truss Intersections Without a Configurable Universal Block.

The EVT290S-4WC is used where an approved layout requires four square truss directions meeting at one central intersection.

01
Lighting Grids
The EVT290S-4WC forms central four-direction intersections in overhead or freestanding lighting structures.
02
Stage Frameworks
The EVT290S-4WC builds central stage-grid intersections with a dedicated 4-way cross junction.
03
Ceiling Grids
The EVT290S-4WC forms four-direction cross intersections in suspended or supported grid layouts.
04
Trade Show Structures
The EVT290S-4WC creates central intersections for booth frames and overhead exhibit structures.
05
Modular AV Structures
The EVT290S-4WC connects four structural runs in approved display and production frameworks.

Who It’s For

For Teams Building Fixed 4-Way Junctions in 290 mm Square Truss Systems.

The EVT290S-4WC is designed for professional users assembling compatible modular square truss systems.

Event Production Companies
Use the EVT290S-4WC for fixed four-direction grid and stage layouts.
Trade Show Contractors
Use the EVT290S-4WC in modular booth and exhibit structures requiring a four-way intersection.
Rental Companies
Stock the EVT290S-4WC for inventory requiring a dedicated 4-way cross junction.
Stage Technicians
Use the EVT290S-4WC to assemble approved four-direction truss junctions.
Scenic and Fabrication Shops
Use the EVT290S-4WC in fixed structural frames and custom modular builds.
AV Integrators
Use the EVT290S-4WC for display, video wall, and equipment-support structures.

Connection Hardware

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

The EVT290S-4WC 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 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, 90-Degree

System Compatibility

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

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

Assembly Overview

Align All Four Directions 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 to match the approved four-direction layout and connection plane.
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 directions and all connection hardware before lifting or applying load.

Safety & Engineering

Cross-Junction Capacity Depends on the Complete Engineered Structure.

The EVT290S-4WC 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.
