EVT290S-Hinge 0–180-Degree Rotatable 2-Way Truss Hinge.
An Adjustable 290 mm Aluminum Pivot Component for Variable-Angle Truss Geometry, Folding Structures, and Custom Layouts.

The EVT290S-Hinge is a 2-way adjustable pivot component for compatible 290 mm square aluminum truss systems. Unlike a fixed-angle corner, the hinge allows the relationship between two connected truss directions to be changed through a nominal range of 0 to 180 degrees. This makes the component suitable for variable-angle layouts, folding assemblies, temporary structures, trade show systems, staging, motion capture frameworks, and other modular installations where the final geometry cannot be produced efficiently with fixed-angle corners alone. The assembly is manufactured from EN AW-6082 T6 aluminum and uses 50 mm main tubing with a 3 mm wall thickness together with 20 mm diagonal bracing with a 2 mm wall thickness.

Product Overview

Variable Geometry Instead of a Single Fixed Angle.

The primary functional difference between the EVT290S-Hinge and a conventional truss corner is adjustability. A fixed-angle component defines one relationship between connected truss sections. The hinge allows that relationship to vary within its stated 0 to 180-degree range, giving the designer substantially more control over the resulting geometry.

0–180-Degree Adjustment

The pivot geometry allows the relative angle between the two truss connections to be varied rather than permanently fixed.

2-Way Pivot Connection

The component connects two truss directions through a central pivoting assembly.

Variable Structural Geometry

One component can support multiple angular configurations where the final angle depends on the intended structural layout.

Heavy-Duty Main Tubing

The assembly uses 50 mm outside-diameter aluminum main tubing with a 3 mm wall thickness.

Common Applications

Adjustable Geometry Expands the Number of Structures That Can Be Built from Standard Truss Components.

The EVT290S-Hinge is most useful when the required structural angle is variable, site-dependent, non-standard, or intentionally adjustable during the planning or assembly process.

Custom Truss Layouts

Create structural transitions at angles that are not available as standard fixed-angle corner components.

Folding Structures

The pivot geometry can be incorporated into assemblies where connected truss sections must change position as part of the intended configuration.

Trade Show Booths

Support angled booth structures, custom crowns, variable architectural forms, and layouts that must adapt to different exhibit footprints.

Stage Structures

Create application-specific truss transitions where fixed 30, 45, 60, or 90-degree geometry is not appropriate.

Motion Capture Systems

Adjust perimeter or support geometry around specialized capture spaces, cameras, sensors, and tracking equipment.

Modular Installations

Use variable-angle connections in structures that may require different geometry between installations.

Who It’s For

For Professionals Who Need More Geometric Control Than a Fixed Corner Can Provide.

The EVT290S-Hinge is intended for professional applications where the desired angle is not known until system design, where multiple angle configurations are required, or where a fixed-angle corner would unnecessarily restrict the structure.

Event Production Companies

For custom stage, scenic, lighting, and event structures requiring non-standard angular geometry.

Trade Show Contractors

For modular booth systems that must adapt to different footprints, design concepts, and venue constraints.

Motion Capture Integrators

For adjustable technical frameworks built around capture volumes, camera arrays, sensors, or tracking hardware.

Rigging Professionals

For approved configurations requiring a variable-angle connection between compatible truss sections.

Scenic & Fabrication Shops

For prototypes, irregular structures, modular builds, and designs where standardized fixed-angle corners are too restrictive.

AV & Technical Integrators

For equipment-support structures requiring adjustable relationships between cameras, sensors, displays, lighting, or other technical elements.

Connection Hardware

Conical Couplers, Tapered Pins, and R-Clips.

The EVT290S-Hinge interfaces with compatible 290 mm square truss sections through a conical connection system. The adjoining truss sections are mechanically connected using conical couplers, tapered pins, and retaining clips.

Conical Couplers

The couplers create the mechanical interface between the hinge receivers and adjoining truss receivers.

Tapered Pins

Tapered pins secure the conical connection through the aligned receiver geometry.

R-Clips

R-clips retain the tapered pins after installation and complete the external truss connection.

The hinge angle and the truss connections are separate elements of the assembly.

Verify the intended hinge position as well as the complete installation of every conical coupler, tapered pin, and R-clip before the structure is lifted or loaded. The ability of the hinge to rotate should not be interpreted as permission to change structural geometry while the assembly is under load.

System Compatibility

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

The EVT290S-Hinge is designed around a nominal 290 mm square profile and 50 mm main tubing. Compatibility with another truss component requires more than matching the nominal outside dimensions. Receiver position, conical connector geometry, chord spacing, component orientation, and applicable structural data must also correspond.

EVT290S Compatibility

The hinge is configured for the EVT290S nominal 290 mm square truss geometry.

F34 Compatibility

The product source identifies the hinge for compatible F34-style 290 mm square truss systems.

Standard 290 mm Systems

Other standard 290 mm square conical systems should be dimensionally verified before the components are combined.

Variable Angle Geometry

Compatibility must account not only for physical connection but also for the intended operating angle and resulting structural configuration.

Physical fit does not establish structural equivalence.

A hinge may physically connect to another 290 mm truss component without the complete assembly having equivalent structural properties. Verify connector dimensions, tubing configuration, material, hinge orientation, system load data, and engineering requirements before combining components from different systems.

Assembly Overview

Set the Required Geometry Before the Structure Is Placed Under Load.

The defining characteristic of the EVT290S-Hinge is its ability to change angle. That flexibility also means the intended geometry should be established as part of the assembly process. The final hinge position affects the direction, dimensions, support conditions, and load path of every connected truss section.

01 — Inspect the Hinge

Check the pivot assembly, main tubing, bracing, welds, receivers, couplers, pins, and retaining clips for damage or abnormal wear.

02 — Determine the Required Angle

Establish the intended hinge orientation and angle from the approved layout before completing the surrounding truss assembly.

03 — Position the Hinge

Adjust the pivot to the required geometry while the structure is in a condition suitable for assembly and adjustment.

04 — Connect the Truss

Align the adjoining truss receivers and install compatible conical connection hardware without forcing mismatched geometry.

05 — Secure Connection Hardware

Fully seat the tapered pins and install all required R-clips at the truss connection interfaces.

06 — Verify the Final Configuration

Confirm hinge position, truss alignment, connection security, support geometry, and the complete assembled shape before loading or lifting.

Safety & Engineering

Adjustability Changes Geometry, and Geometry Changes Structural Behavior.

The structural behavior of an adjustable hinge cannot be defined by the 0–180-degree movement range alone. Changing the hinge angle changes the relationship between connected truss sections and can alter span geometry, support reactions, load direction, component forces, and the behavior of the complete structure.

Inspect the pivot assembly, chords, braces, welds, receivers, connection hardware, and adjoining truss before use.

Remove components from service if cracks, permanent deformation, damaged welds, excessive wear, or other structural defects are identified.

Establish the required hinge angle before the structure is subjected to its intended loading condition.

Do not assume that every position within the 0–180-degree movement range has the same structural capacity.

Do not intentionally reposition the hinge while the truss assembly is carrying suspended or otherwise unsupported loads unless the complete engineered procedure specifically permits it.

Verify complete seating of all conical couplers, tapered pins, and retaining clips before loading the structure.

Account for the selected hinge angle when evaluating span, supports, bracing, and load paths.

Include gravity, dynamic, transverse, wind, and other applicable environmental or operational loads in the complete structural evaluation.

Have the complete variable-angle structure reviewed by a licensed professional engineer when required by the configuration, application, or jurisdiction.

Assembly and adjustment should be performed by personnel familiar with professional aluminum truss systems and rigging procedures.

What is the overall width?

The listed overall truss width is 290 mm / 11.41 in.

How much does the EVT290S-Hinge weigh?

The listed component weight is 18 lb / 8.16 kg.

What material is used?

The component is manufactured from EN AW-6082 T6 aluminum alloy.

What are the main tubing dimensions?

The main tubing is 50 mm outside diameter with a 3 mm wall thickness.

What bracing is used?

The listed diagonal bracing uses 20 mm tubing with a 2 mm wall thickness.

What connection system does it use?

The EVT290S-Hinge uses a conical connection system with couplers, tapered pins, and R-clips for connecting adjoining truss sections.

What systems are listed as compatible?

The source identifies compatibility with EVT290S, F34, and standard 290 mm square truss systems. Actual dimensional and structural compatibility should still be verified before mixed-system use.

Why use an adjustable hinge instead of a fixed-angle corner?

A fixed-angle corner is efficient when the required geometry is known and does not change. An adjustable hinge is more appropriate when the angle is non-standard, variable, site-dependent, or when one component must support multiple layout configurations.

Can the hinge be adjusted while the structure is loaded?

The product's range of motion should not be interpreted as authorization to reposition the hinge under load. Hinge adjustment should be treated as part of the controlled assembly and configuration process unless an engineered procedure specifically establishes otherwise.

Is structural capacity the same at every hinge angle?

That should not be assumed. Changing the hinge angle changes the geometry of the complete structure and can change load paths, component forces, span relationships, and support reactions. Capacity should be evaluated for the actual assembled configuration.
