4-Way 90-Degree T-Junction Overview

A Fixed Junction for 290 mm Square Truss.

The EVT290S-4WT is a fixed 4-way 90-degree T-junction. It is a component for compatible 290 mm square aluminum truss layouts. It is not a 3-way T-junction, a 4-way cross junction, a 3-way 90-degree corner, or a universal junction block.

Product Identity
EVT290S-4WT is the brushed-aluminum 4-way 90-degree T-junction in the EVT290S square-truss family.
Fixed Configuration
The connection layout is fixed. Select this component only where the project drawing calls for the specified four-direction junction.
290 mm Square Profile
The product is intended for compatible 290 mm / 11.41 in square-truss connection interfaces.
Brushed Aluminum
The natural aluminum finish is intended for layouts where visible truss is part of the finished environment.

What Does a 4-Way 90-Degree T-Junction Connect?

One Vertical Truss Run and Two Horizontal 90-Degree Runs.

The EVT290S-4WT connects Up, Down, Left, and Right truss directions. In a planned layout, the Up and Down directions form a continuous vertical truss run. The Left and Right directions extend horizontal truss runs at 90 degrees. This creates a fixed intersection for a compatible stage, exhibit, lighting, AV, or display truss system.

Up and Down
Use the Up and Down directions for a continuous vertical truss line where specified by the project drawing.
Left and Right
Use the Left and Right directions for horizontal truss runs that extend from the vertical line at 90 degrees.
Fixed Intersection
The component establishes the connection configuration. It does not establish the completed system’s support, span, or loading limits.

Where Is This T-Junction Used?

For Visible Truss Intersections in Event and Display Structures.

Use the EVT290S-4WT in a compatible layout where a vertical truss line intersects with left-and-right horizontal runs. The brushed aluminum finish is well suited to applications where the natural aluminum truss appearance remains visible.

01
Trade-Show Exhibit Frames
Use at visible intersections in exhibit frames, overhead identity elements, and modular display structures.
02
Stage and Scenic Structures
Use in compatible stage frames, scenic structures, backdrop systems, and presentation layouts with exposed aluminum truss.
03
Lighting and AV Frameworks
Use in planned lighting, video, camera, projection, audio, and cable-management truss layouts.
04
Retail and Experiential Displays
Use in compatible branded environments, product displays, museums, retail activations, and experiential installations.

Why Choose Brushed Aluminum?

Choose a Finish That Keeps the Truss Visually Present.

Choose EVT290S-4WT brushed aluminum when the truss is intended to remain visible or must match existing natural-aluminum EVT290S components. The brushed finish supports a coordinated aluminum appearance in exhibit, stage, lighting, AV, display, and production environments.

Match Natural Aluminum Truss
Use with compatible brushed-aluminum EVT290S sections and components where a consistent natural aluminum finish is required.
Keep the Structure Visible
Select brushed aluminum when exposed truss contributes to the visual character of the exhibit, stage, or display environment.
Different From Matte Black
Matte black is often selected when truss should visually recede. Brushed aluminum is the finish choice for a visible natural-metal appearance.
Finish Does Not Set Capacity
Finish selection does not change load capacity, connection requirements, inspection requirements, engineering review, or safety obligations.

What Must Match Before Connection?

Verify the Interface Before Combining Components.

The EVT290S-4WT is intended for compatible EVT290S, F34-format, and matching 290 mm square truss systems using conical connections. Matching profile size alone does not confirm compatibility. Verify 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
Use with F34-format truss only when receiver spacing and Conical Coupler dimensions match.
Other 290 mm Square Truss
Other 290 mm square conical systems require dimensional and engineering verification before components 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.

How Is the T-Junction Connected?

Plan the Connection, Then Inspect Every Required Point.

Assembly should be completed by trained personnel using compatible components, the project drawing, the approved support or rigging plan, and sufficient hardware for every required connection. The supplied hardware covers two connecting sides only.

01 — Inspect Components
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 Layout
Position the T-junction to match the approved Up, Down, Left, and Right project layout before connection work begins.
03 — Plan Hardware
Use the supplied hardware for its two included connecting sides. Identify compatible hardware for other required connection positions.
04 — Align Mating Truss
Bring compatible truss faces together evenly. Connections should close without forcing, spreading, or pulling components into alignment.
05 — Secure the Connection
Fully install each required Coupler-Pin and secure every installed Coupler-Pin with its R-Clip.
06 — Final Inspection
Verify retention, component condition, support planning, and the completed configuration before movement, lifting, rigging, or load application.
If a Connection Does Not Close
Stop assembly. Check 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 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.
Documentation and Project Review
