EVT290S-3WT 3-Way T-Junction.
For F34 Square Truss Systems.
The EVT290S-3WT is a brushed-aluminum fixed 3-way T-junction for compatible EVT290S, F34, and matching 290 mm square truss systems. Its fixed T-junction configuration supports vertical or horizontal truss layouts for overhead lighting, speaker clusters, modular exhibit frames, stage structures, ceiling grids, AV systems, and other compatible production frameworks.
Product Facts
F34 3-Way T-Junction Overview
A Fixed T-Junction for F34 Square Truss Systems.
The EVT290S-3WT is a fixed 3-way T-junction for compatible 290 mm square truss systems. It is used in vertical or horizontal T-junction layouts where the project drawing calls for this specific connection configuration. It is not a 3-way 90-degree corner and it is not a universal junction block.
How the T-Junction Is Used
A Fixed T-Junction for Compatible Truss Layouts.
Use the EVT290S-3WT when the project drawing requires a fixed three-way T-junction in a compatible 290 mm square-truss system. The component can be used in vertical or horizontal layouts for overhead lighting, speaker clusters, ceiling grids, stage structures, AV systems, modular exhibit frames, and production frameworks.
Common Applications
For Lighting, Stage, AV, and Exhibit Truss Layouts.
The EVT290S-3WT can be incorporated into compatible, project-specific truss systems that use a fixed 3-way T-junction. The final system determines support points, loading, rigging, equipment attachment, connection hardware, and required approvals.
Brushed Aluminum Finish
A Finish for Visible Aluminum Truss Layouts.
The EVT290S-3WT uses a brushed aluminum finish that matches other aluminum EVT290S components in a compatible system. It is suited to visible technical structures, lighting grids, exhibit frames, display environments, and production layouts where a natural aluminum truss appearance is desired.
Included Connection Hardware
Hardware for Two Connecting Sides.
The confirmed hardware package is supplied for two connecting sides of the EVT290S-3WT. Its fixed 3-way T-junction configuration does not mean that hardware for three sides is included. Confirm the project drawing and connection schedule to identify any additional compatible hardware needed for the remaining truss connection.

System Compatibility
Verify the Connection Interface Before Combining Components.
The EVT290S-3WT 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.
Assembly Overview
Set the T-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.
Safety and Engineering
A T-Junction Is Not a Standalone Load or Span Rating.
The EVT290S-3WT 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.
Product Questions
EVT290S-3WT Frequently Asked Questions.
What is an F34 3-way T-junction used for?
A fixed 3-way T-junction is used where a compatible 290 mm square-truss layout calls for a T-junction connection. The EVT290S-3WT can be used in vertical or horizontal truss layouts for overhead lighting, speaker clusters, ceiling grids, stage structures, AV systems, trade-show displays, and other compatible frameworks.
Is the EVT290S-3WT a 3-way corner?
No. The EVT290S-3WT is a fixed 3-way T-junction, not a 3-way 90-degree corner and not a universal junction block. Use the component specified by the project drawing.
What connection hardware is included?
The confirmed package contains hardware for two connecting sides: 8 conical couplers, 16 coupler-pins, and 16 r-clips. Confirm the project drawing and connection schedule for any additional compatible hardware needed for the remaining truss connection.
Why choose the brushed aluminum finish?
The brushed aluminum finish matches compatible natural-aluminum EVT290S components and is suited to visible lighting, exhibit, display, and production truss frameworks. It does not change capacity, engineering, connection, or inspection requirements.
Is it compatible with all 290 mm square truss?
No compatibility should be assumed from size or appearance alone. Confirm receiver spacing, coupler dimensions, chord spacing, alignment, component condition, current manufacturer documentation, and applicable engineering information before mixing components.
Does this T-junction establish capacity for a finished truss system?
No. Capacity depends on the complete configuration, including connected truss, supports, rigging, connection hardware, applied loads, attachments, environmental conditions, venue requirements, and approvals.
