F34 4-Way T-Junction Overview

A Fixed T-Junction for F34 Square Truss Systems.

The EVT290S-4WT Black is a fixed 4-way T-junction for compatible 290 mm square truss systems. It provides Up, Down, Left, and Right connection directions at a planned junction point. It is not a 3-way T-junction, a 4-way cross junction, a 3-way 90-degree corner, or a universal junction block.

Fixed 4-Way T-Junction
Use this component where a compatible truss system requires an Up, Down, Left, and Right junction at a planned intersection.
Vertical and Horizontal Layouts
The product can be positioned within compatible vertical-column and intersecting horizontal-grid layouts specified by the project drawing.
500 mm Overall Size
The 500 × 500 × 500 mm outer dimensions fit within planned 290 mm square-truss layouts.
Fixed Connection Layout
The EVT290S-4WT Black is a dedicated fixed T-junction component, not an adjustable or universal connection block.

How the T-Junction Is Used

A Planned Junction for Columns and Intersecting Grids.

Use the EVT290S-4WT Black when the project drawing requires a fixed four-direction T-junction in a compatible 290 mm square-truss system. Its Up, Down, Left, and Right layout can be used in compatible vertical columns, lighting grids, ceiling grids, stage structures, AV layouts, exhibit systems, and production frameworks.

Vertical Column Intersections
Use the fixed T-junction where a reviewed truss layout requires a vertical column to meet intersecting horizontal truss components.
Lighting Grid Junctions
Use in compatible lighting-grid layouts where approved lighting positions and related production elements require a planned junction point.
Exhibit Frame Intersections
Use in compatible exhibit and trade-show layouts where a vertical support member meets horizontal display-frame directions.
Stage and AV Frameworks
Use in planned stage, video, projection, camera, lighting, audio, and cable-management truss layouts.
T-Junction Use Note
The EVT290S-4WT Black is a component for a compatible completed truss layout. It does not independently approve or rate a lighting grid, vertical column, stage structure, AV framework, exhibit structure, ceiling grid, suspended configuration, or public-facing installation.

Common Applications

For Intersections in Production and Exhibit Systems.

The EVT290S-4WT Black can be incorporated into compatible, project-specific truss systems that use a fixed 4-way T-junction. The completed system determines support points, loading, rigging, equipment attachment, connection hardware, bracing, and required approvals.

01
Lighting Grids
Use at planned junctions in lighting-grid systems for theater, studio, venue, and event-production applications.
02
Stage Structures
Use in compatible stage frames, scenic structures, video frameworks, backdrop systems, and presentation layouts.

05
Visible Black Frameworks
Use the matte black finish in layouts where the truss is intended to visually recede within a stage, studio, exhibit, or display environment.

Matte Black Powder-Coat Finish

A Finish for Low-Visibility Truss Layouts.

The EVT290S-4WT Black uses a matte black powder-coat finish for compatible black EVT290S components. It is suited to stage, theater, studio, AV, exhibit, and display environments where a darker truss appearance is desired or where visible structural elements should be less prominent.

Theater and Stage
Use matte black truss in compatible stage and theater layouts where truss should visually recede behind lighting, scenery, curtains, and production elements.
Studio and AV Layouts
Use in compatible studio, broadcast, camera, lighting, and AV truss systems that call for a coordinated black finish.
Exhibit and Display Systems
Use in compatible exhibit and display structures where matte black supports the visual direction of the installation.
Finish Does Not Set Capacity
Finish selection does not change load capacity, connection requirements, inspection requirements, engineering review, or safety obligations.

System Compatibility

Verify the Connection Interface Before Combining Components.

The EVT290S-4WT Black is intended for compatible EVT290S, F34-format, 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 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 T-Junction Layout
Position the component to match the approved Up, Down, Left, and Right truss layout before connection work begins.
03 — Plan Connection Hardware
The supplied hardware covers two connecting sides. Identify and obtain compatible hardware for the other required connection positions.
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 T-Junction Is Not a Standalone Load or Span Rating.

The EVT290S-4WT Black 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 T-junction or the completed truss system.
Do not treat an individual T-junction as evidence that a lighting grid, vertical column, 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.
