Product Description

Variable Angle Truss Hinge – Right Side – 88mm Adjustable Connector (EVT290A-H180R)

The EVT290A-H180R is a heavy-duty Right-Side variable angle hinge connector designed for 290 mm square conical aluminum truss systems. The “R” designation indicates this unit is configured for the right side of the truss connection (typically paired with a Left-Side unit). This versatile component is a critical tool for truss ground support systems, allowing for the safe erection of vertical towers via the “tip-up” method.

Function & Compatibility:

By installing this hinge (paired with the corresponding Left-Side unit, EVT290A-H180L) between the truss tower and the base, installers can assemble the tower horizontally on the ground and then safely pivot it into the vertical position. It can also be used to create custom angular junctions ranging from 0 to 180 degrees for non-standard geometric shapes. It is fully F34 Compatible, ensuring seamless integration with EVT290S and most major 290mm square truss brands.

Key Features

• Orientation: Right-Side Hinge (identified by the ‘R’ suffix).
• Hinge Body Length: Measures 88mm (3.46″) in length.
• Tower Erection Aid: Facilitates the safe lifting of ground support towers.
• Variable Angle Design: Allows for custom angles between 0 and 180 degrees.
• Compatibility: F34 Compatible design integrates seamlessly with standard 290mm square truss systems.
• Robust Construction: Heavy-duty hinge mechanism designed to withstand erection stresses.

Designed by Evolve Truss, this hinge is an indispensable tool for production companies that regularly deploy ground support systems or require flexible design options.

⚠️ Safety & Engineering Notice

❗ Structural Warning:

• Static Use: While the hinge is load-bearing during the erection phase, it behaves differently than a rigid corner block. When used in a static structure, the hinge position must be secured, and the overall structural stability (bracing/guying) must be verified.
• Engineering Review: The purchase of this product does not authorize specific installations. A licensed professional engineer shall review all structures, lighting plots, or any other product uses.

Important Guidelines for Safe Use:

• Inspect the hinge pin and leaves for wear or deformation before every use.
• Ensure all conical couplers and safety pins are fully engaged before lifting or loading.
• Do not exceed the load capacity of the truss system.
• Truss assembly should be carried out only by those familiar with trussing and rigging.

⚠️ Compatibility Warning

Crucial Steps for Safe Assembly:

• Brand Mixing: While F34 compatible, always test-fit connections with other brands on the ground before lifting.
• Orientation Check: Ensure you have the correct pairing of Left (L) and Right (R) hinges for your specific configuration.
