Product Description

Variable Angle Low Profile Truss Hinge – Non-Lockable 180-Degree Connector (EVT290A-TMH)

The EVT290A-TMH is a specialized Variable Angle Low Profile Truss Hinge designed for 290 mm square conical aluminum truss systems. Unlike heavy-duty tower erection hinges, the TMH features a streamlined, compact design that reduces visual bulk. It offers a full 180-degree range of rotation, making it the ideal solution for creating custom geometric shapes, angled arches, or non-standard corner connections where a sleek, unobtrusive appearance is required.

Function & Compatibility:

This unit replaces standard rigid corners, offering riggers the freedom to adjust the angle of the truss run to fit specific architectural constraints. Please note that this is a free-moving, non-lockable hinge. It is designed to allow the truss to find its angle within a closed structure (like a hexagon or spider web) or an arch where gravity or bracing maintains the shape. It is fully F34 Compatible, ensuring seamless integration with EVT290S and most major 290mm square truss brands.

Key Features

• 180-Degree Rotation: Full freedom of movement to create angles from flat (0°) to folded (180°).
• Non-Lockable Mechanism: Free-moving hinge designed for self-stabilizing geometric shapes or braced structures.
• Compatibility: F34 Compatible design integrates seamlessly with standard 290mm square truss systems.
• Low Profile Design: Compact form factor for a cleaner, less industrial aesthetic.
• Material Type: Precision-machined from high-grade Aluminum Alloy EN AW-6061 T6.
• Versatile Application: Perfect for creating arches, hexagons, or custom angled display frames.

Designed by Evolve Truss, the EVT290A-TMH gives designers the flexibility to break away from right angles without compromising the visual flow of the structure.

⚠️ Safety & Engineering Notice

❗ Structural Warning:

• Non-Locking: This is a non-lockable hinge. It does not lock into a fixed position. Do not rely on the hinge alone to hold an angle.
• Structural Stability: The shape of the structure must be maintained by the geometry of the design (e.g., a closed loop) or by external bracing/guying. Do not exceed the load capacity of the truss system.

Important Guidelines for Safe Use:

• Inspect the hinge mechanism for wear or deformation before every use.
• Ensure all conical couplers and safety pins are fully engaged before lifting or loading.
• Do not use if the hinge shows signs of damage or excessive play.
• The purchase of this product does not authorize specific installations; a licensed professional engineer shall review all structures, particularly those utilizing non-rigid corners.

⚠️ Compatibility Warning

Crucial Steps for Safe Assembly:

• Brand Mixing: While F34 compatible, always test-fit connections with other brands on the ground before lifting.
• System Geometry: Confirm that the node spacing matches your existing truss to ensure a proper fit.
