Product Overview

A Fixed Corner That Joins Three Truss Directions at a Single 90-Degree Junction.

The EVT290S-3WC creates a three-direction 90-degree junction while maintaining the geometry of compatible 290 mm square conical truss.

3-Way 90-Degree Geometry
The EVT290S-3WC creates a fixed three-direction corner for modular square truss layouts.
0.5 m Corner Section
The EVT290S-3WC 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-3WC uses couplers, tapered pins, and R-clips at each of its three connection points.

Common Applications

Used to Build Three-Way Junctions Without a Configurable Universal Block.

The EVT290S-3WC is used where an approved layout requires three square truss directions meeting at 90 degrees.

01
Lighting Grids
The EVT290S-3WC forms fixed three-direction junctions in overhead or freestanding lighting structures.
02
Stage Frameworks
The EVT290S-3WC builds branching stage structures at a dedicated three-way corner.
03
Ceiling Grids
The EVT290S-3WC forms three-direction corner transitions in suspended or supported grid layouts.
04
Trade Show Structures
The EVT290S-3WC forms fixed corners for booth frames, entrances, and overhead exhibit structures.
05
Modular AV Structures
The EVT290S-3WC connects three structural runs in display and production frameworks.

Who It’s For

For Teams Building Fixed 3-Way Corners in 290 mm Square Truss Systems.

The EVT290S-3WC is designed for professional users assembling compatible modular square truss systems.

Event Production Companies
Use the EVT290S-3WC for fixed three-direction grid and stage layouts.
Trade Show Contractors
Use the EVT290S-3WC in modular booth and exhibit structures requiring a 90-degree junction.
Rental Companies
Stock the EVT290S-3WC for inventory requiring a dedicated 3-way corner configuration.
Stage Technicians
Use the EVT290S-3WC to assemble approved three-direction truss junctions.
Scenic and Fabrication Shops
Use the EVT290S-3WC in fixed structural frames and custom modular builds.
AV Integrators
Use the EVT290S-3WC for display, video wall, and equipment-support structures.

Connection Hardware

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

The EVT290S-3WC uses a conical connection system. Each of its three connection points requires the same set of connection hardware.

Conical Couplers
Couplers seat between the corner 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 three connection points on the EVT290S-3WC 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)
Corner Geometry 3-Way, 90-Degree

System Compatibility

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

The EVT290S-3WC 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-3WC is designed for the EVT290S square aluminum truss series.
F34
The EVT290S-3WC is compatible with F34-format truss when receiver spacing and conical connection dimensions match.
Other 290 mm Square Systems
The EVT290S-3WC may fit other 290 mm square conical systems after dimensional verification.
50 mm Clamps
The main chords of the EVT290S-3WC accept compatible clamps designed for standard 50 mm truss tubing.

Assembly Overview

Align All Three Directions Before Final Connection Inspection.

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

01 — Inspect the Corner
Check chords, braces, welds, receivers, couplers, pins, and clips before use.
02 — Confirm Orientation
Position the EVT290S-3WC to match the approved three-direction 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 three active directions and all connection hardware before lifting or applying load.

Safety & Engineering

Corner Capacity Depends on the Complete Engineered Structure.

The EVT290S-3WC 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.
