The natural aluminum finish can complement trade-show displays, product presentations, graphics structures, and branded environments.
Matching EVT290S Components
Use with compatible brushed-aluminum EVT290S sections and components where the project calls for a consistent finish.
Finish Does Not Set Capacity
Finish selection does not change load capacity, connection requirements, inspection requirements, engineering review, or safety obligations.

Included Connection Hardware

Hardware for Two Connecting Sides.

The confirmed hardware package is supplied for two connecting sides of the EVT290S-4WC. Its fixed 4-way cross-junction configuration does not mean that hardware for all four sides is included.

System Compatibility

Verify the Connection Interface Before Combining Components.

The EVT290S-4WC is intended for compatible EVT290S, F34, and matching 290 mm square truss systems using conical connections. Compatibility requires more than matching profile size: confirm receiver spacing, coupler dimensions, chord spacing, alignment, component condition, current manufacturer documentation, and applicable engineering information.

EVT290S Series
Designed for the EVT290S square aluminum truss series.
F34 Format
Compatible with F34-format truss when receiver spacing and conical connection dimensions match.
Other 290 mm Square Truss
Other 290 mm square conical systems may require dimensional and engineering verification before they are combined.
Compatible 50 mm Clamps
The 50 mm / 1.96 in main chords accept compatible clamps for approved attachments within the completed system design.

Assembly Overview

Set the Cross Junction Position, Then Inspect Every Required Connection.

Assembly should be completed by trained personnel using compatible components, the project drawing, supplied hardware for the two included connecting sides, and the approved support or rigging plan. Work on a stable surface and retain access to inspect every required connection position.

01 — Inspect the Component
Check chords, braces, welds, receivers, conical couplers, coupler-pins, and r-clips. Do not use damaged, worn, contaminated, or improperly fitting components.
02 — Confirm the Cross Layout
Position the component to match the approved vertical or horizontal cross-junction layout before connection work begins.
03 — Install Supplied Couplers
Insert the supplied conical couplers into the compatible receivers for the two included connecting sides.
04 — Align Mating Truss
Bring compatible truss faces together evenly. They should close without forcing, spreading, or pulling the connections into alignment.
05 — Secure Coupler-Pins and r-Clips
Fully install each required coupler-pin and secure every installed coupler-pin with its r-clip.
06 — Perform Final Inspection
Verify connection retention, support planning, and the completed configuration before movement, lifting, rigging, or load application.
If a Connection Does Not Close
Stop assembly. Inspect receiver spacing, coupler fit, debris, hardware condition, damage, and alignment. Do not modify the component or drive a coupler-pin against resistance.

Safety and Engineering

A Cross Junction Is Not a Standalone Load or Span Rating.

The EVT290S-4WC does not independently establish a span, load, wind, suspension, or freestanding-structure rating. Determine suitability from the complete configuration, including connected components, spans, orientation, supports, connection hardware, bracing, rigging method, applied loads, lighting, AV equipment, displays, signage, base plates, ballast or anchorage, environmental conditions, venue requirements, and applicable approvals.

Do not use a straight-section load-span table to independently rate this cross junction or the completed truss system.
Do not treat an individual cross junction as evidence that an overhead grid, lighting cluster, stage structure, AV framework, exhibit structure, ceiling grid, suspended configuration, or public-facing structure has adequate capacity.
Confirm project-specific support, rigging, bracing, base-plate, ballast, and anchorage plans before erection or loading.
Assess wind, banners, screens, displays, suspended equipment, public access, and other operational or environmental forces as part of the complete project review.
Inspect every conical coupler, coupler-pin, r-clip, clamp, base connection, sling, shackle, safety cable, and attachment point before use.
Use trained personnel and obtain the project-specific engineering, facility, venue, and regulatory review required for the intended use.
