EVT290X-12DA Black 12-Degree Fixed-Angle Square Truss Corner.
A Heavy-Duty 290 mm Matte Black Corner for Controlled Truss Direction Changes and Sloped Structures.

The EVT290X-12DA Black is a fixed 12-degree 2-way corner designed for compatible 290 mm square aluminum truss systems. Its gradual fixed-angle geometry allows a truss run to transition through a controlled 12-degree change rather than a standard 90-degree corner. Manufactured from EN AW-6082 T6 aluminum with 50 mm main chords and a heavy-duty 3 mm wall thickness, the EVT290X-12DA Black uses a matte black powder-coat finish and conical connection system for professional modular structures.

Product Overview

A Fixed 12-Degree Corner for Precise Directional Transitions.

The EVT290X-12DA Black introduces a controlled 12-degree change between two compatible 290 mm square truss sections, making it useful where a gradual slope or non-standard directional transition is required.

12-Degree Fixed Geometry
Provides a repeatable 12-degree directional transition without adjustable hinges or moving components.
2-Way Connection
Connects two truss sections through a fixed-angle corner for gradual changes in the structural run.
Heavy-Duty Main Chords
Uses 50 mm OD aluminum main tubing with a 3 mm wall thickness.
Matte Black Powder Coat
Professional matte black finish helps reduce visual reflection in stage, studio, exhibit, and production environments.

Common Applications

Introduce Controlled Slopes and Gradual Direction Changes into Modular Truss Layouts.

The EVT290X-12DA Black is designed for applications where a standard straight section or 90-degree corner cannot provide the required geometry.

01
Sloped Roof Structures
Introduce a fixed pitch into compatible roof-grid layouts where a gradual slope is part of the approved structural design.
02
Trade Show Structures
Create angled architectural elements and non-orthogonal transitions in custom booth designs.
03
Motion Capture Systems
Develop custom cage geometries and polygonal truss layouts around specialized capture environments.
04
AI & Sensor Truss Systems
Create gradual directional changes in modular frameworks supporting cameras, sensors, and related equipment.
05
Stage & Studio Structures
Create controlled angled transitions while maintaining a low-visibility matte black appearance.

Who It’s For

For Professionals Building Non-Standard 290 mm Truss Geometry.

Designed for professional users who need a precise fixed-angle component rather than a standard straight section or conventional right-angle corner.

Event Production Companies
For custom stage, roof, lighting, and production structures requiring controlled angular transitions.
Trade Show Contractors
For architectural booths and exhibits incorporating slopes and non-90-degree geometry.
Motion Capture Integrators
For custom perimeter and enclosure geometries surrounding specialized capture volumes.
Stage Technicians
For approved truss assemblies requiring a repeatable 12-degree directional change.
Scenic & Fabrication Shops
For custom modular frameworks and architectural truss structures.
Studio & AV Integrators
For camera, sensor, display, simulation, studio, and equipment-support structures where matte black truss is preferred.

Connection Hardware

Conical Couplers, Tapered Pins, and R-Clips.

The EVT290X-12DA Black uses a conical connection system with couplers, tapered pins, and R-clips for joining the corner to compatible truss sections.

Conical Couplers
Couplers seat between the fixed-angle corner receivers and adjoining truss receivers.
Tapered Pins
Tapered pins secure the conical couplers through the aligned receiver holes.
R-Clips
Retaining clips secure the tapered pins after installation.
Confirm hardware requirements for the complete structure.

Use only compatible conical connection hardware and verify that every coupler, tapered pin, and R-clip is completely seated and secured before lifting or applying load.

System Compatibility

EVT290S, F34, and Compatible 290 mm Square Truss Systems.

The EVT290X-12DA Black uses a 290 mm square profile, 50 mm main chords, and a conical connection system. Mixed-system compatibility requires verification of receiver spacing, coupler dimensions, node geometry, overall truss geometry, and applicable structural data.

EVT290S Compatibility
Designed for compatible EVT290S 290 mm square aluminum truss connections.
F34 Compatibility
Listed for F34-style 290 mm square systems when receiver spacing and conical connection dimensions match.
Standard 290 mm Square Systems
May fit other compatible 290 mm square conical systems after dimensional and connection verification.
50 mm Clamp Compatibility
The 50 mm main chords accept compatible clamps designed for standard 50 mm truss tubing.
Mixed-brand compatibility should always be verified.

Matching nominal truss width alone does not confirm structural compatibility. Verify dimensions, conical connector geometry, node spacing, tubing configuration, and engineering requirements before combining components from different systems.

Assembly Overview

Maintain the Intended 12-Degree Orientation During Assembly.

The EVT290X-12DA Black is a fixed-angle component. Confirm that the orientation and direction of the 12-degree transition match the approved structural layout before connecting adjoining truss sections.

01 — Inspect the Corner
Check main chords, braces, welds, receivers, couplers, pins, and clips before assembly.
02 — Confirm Angle Direction
Orient the fixed 12-degree transition in the direction specified by the approved layout.
03 — Insert Couplers
Seat compatible conical couplers into the required receivers.
04 — Align Truss Sections
Bring the mating truss sections into alignment with the fixed-angle receivers without forcing the connection.
05 — Install Pins & R-Clips
Fully seat each tapered pin and secure it with the required R-clip.
06 — Final Inspection
Verify the 12-degree orientation, connection seating, hardware retention, and complete system geometry before lifting or loading.

Safety & Engineering

Fixed-Angle Corner Capacity Depends on the Complete Engineered Structure.

Allowable loading depends on the complete system configuration, span length, supports, bracing, corner orientation, connection details, load placement, environmental forces, and overall structural geometry.

Inspect all main chords, braces, welds, receivers, couplers, pins, and clips before use.
Do not use components showing cracks, bends, deformation, damaged welds, or excessive wear.
Confirm all tapered pins are fully seated and all R-clips are correctly installed.
Do not support loads directly from unverified truss connection points.
Account for the effect of the 12-degree geometry on the complete structure, supports, load paths, and bracing.
Account for applicable gravity, dynamic, transverse, and environmental forces, including wind where applicable.
Confirm the complete structural configuration against applicable load data and engineering requirements.
Have the complete structure reviewed by a qualified engineer when required.
Assembly and installation must be performed by trained and qualified personnel.
