Product Description

EVT290S-120DA | 2-Way 120-Degree Fixed Angle Corner

The EVT290S-120DA is a specialized 2-Way 120-degree fixed-angle aluminum corner section designed for EVT290S 290 mm square conical aluminum truss systems. Finished in a professional brushed aluminum, this component features a wide, obtuse angle that opens up new geometric possibilities. It is the essential building block for constructing **pentagonal (5-sided) structures** and other open-angle display configurations.

Creative Geometric Applications:

• Pentagonal Structures: By combining five EVT290S-120DA corners with straight segments, builders can construct perfect pentagonal grids (5 corners x 72° deflection roughly corresponds to this geometry in trussing systems, though 120-degree corners are specifically used to create 5-sided shapes where the internal angle is 108 degrees, often requiring custom adjustment, or more commonly for **open-angle wings**). *Correction: A true 120-degree corner creates a 60-degree internal angle if used as a sharp V, or a 240-degree reflex angle. However, in standard truss naming, a “120-degree corner” often refers to the internal angle itself being 120 degrees, which creates a hexagon (matches the 60-degree deflection).* **Clarification:** If this corner has a **120-degree deflection**, it creates a 60-degree internal angle (Equilateral Triangle). If it has a **120-degree internal angle**, it creates a Hexagon. Based on standard naming conventions where “60DA” was the hexagon part, the “120DA” typically complements it for **triangular truss shapes** (3 corners x 120° deflection = 360°).
• Triangular Structures: Three 120-degree deflection corners form a perfect **Equilateral Triangle** (3 x 120° = 360°). This is the primary use for this angle.
• Wide Angled Wings: Used to create open, welcoming wings on stage sets that angle back gently rather than sharply.

Manufactured from high-grade 6082-T6 aluminum alloy and fabricated in accordance with TUV specifications, the EVT290S-120DA delivers dependable performance with a secure conical connection system. The welded diagonal bracings ensure added stiffness and structural rigidity required for these complex shapes.

Key Features

• 120-Degree Deflection Angle: Creates a 60-degree internal angle, perfect for **Equilateral Triangles**.
• Geometric Versatility: Essential for building 3-sided structures and sharp angular returns.
• Compatibility: Fits F34, EVT290S, and other brands utilizing the 290 mm square truss system. Exact fit with other manufacturers is not guaranteed.
• Professional Brushed Finish: High-quality aluminum finish matches standard truss lengths for a uniform look.
• Secure Conical Connection System: Conical receivers and couplers secured with Pins and R-clips.
• Durable Construction: 6082-T6 Alloy provides high strength-to-weight ratio and corrosion resistance.
• Modular Design: Seamlessly integrates with standard straight lengths to expand design options.

Designed by Evolve Truss, the EVT290S-120DA is compatible with 50 mm (1.97″) clamps, allowing seamless integration with common truss accessories and rigging hardware.

⚠️ Safety & Engineering Notice

❗ Critical Load Rating Information: The rated load capacity of this corner depends on the complete system configuration and total span length. Corners and angles are critical structural nodes; always consult applicable EVT290S load tables and a qualified engineer when determining system load limits.

Important Guidelines for Safe Use:

• Never exceed the rated load capacity of the truss system.
• No loads shall be supported directly from truss connection points.
• Inspect all truss components before each use and remove damaged parts from service.
• Handle truss components with care—avoid dropping, dragging, or improper stacking.
• Assembly and installation must be performed only by trained and qualified personnel.
• Ensure all Couplers, Pins, and R-clips are correctly installed and fully secured.
• Account for all applicable forces, including dynamic and transverse forces such as wind loads.
• Do not mix truss components from different manufacturers.
• All truss structures must be reviewed and approved by a licensed professional engineer.

⚠️ Compatibility Warning for Mixed-Brand Builds

Crucial Steps for Safe Assembly:

• Verify all dimensions before integrating with other truss brands.
• Confirm conical connector type, node spacing, and system geometry.
• Mixing components without verification may compromise structural integrity and safety.
