Product Overview

Eight Matching Arcs Form One Complete 6-Meter Circle.

The EVT290S-C600 creates a complete 6.0 m diameter circle using eight identical 45-degree arc segments and standard conical truss connections. It is the largest standard circle offered in the EVT290S series.

Eight-Segment Circle
Eight matching 45-degree arc sections form one complete 360-degree circle.
Largest Standard Diameter
At 19.68 ft / 6.0 m, this is the largest standard circle in the EVT290S truss series.
EVT290S Construction
Built from 290 mm square truss with 50 mm main chords and 20 mm diagonal bracing.
Conical Connections
Uses couplers, tapered pins, and R-clips for fast modular assembly.

Common Applications

Sized for Arena, Festival, and Convention-Scale Productions.

At nearly 20 feet across, the EVT290S-C600 is built for large-scale applications where a circular truss element needs to command a major venue.

Arena Concert Tours
Create a large-format circular lighting or scenic element for touring productions.
02
Festival Stages
Build a prominent circular truss feature for outdoor festival stage designs.
03
Convention Center Exhibits
Create an expansive overhead crown or visual perimeter above a major exhibit space.
04
Large Lighting Rigs
Support substantial distributed lighting, audio, and video equipment loads around a wide circular frame.
05
Stadium and Outdoor Events
Provide a durable, large-diameter structural centerpiece for major outdoor productions.

Who It’s For

Built for Teams Producing Major, Large-Scale Events.

Intended for trained personnel planning, assembling, rigging, and inspecting large-format square-truss systems at arena or stadium scale.

Touring Production Companies
For arena and stadium concert tours requiring a large-format circular truss element.
Festival Producers
For outdoor festival stages and major event installations.
Convention and Exhibit Teams
For large convention-center exhibits requiring a commanding overhead structure.
Lighting Designers
For large-scale circular fixture layouts and overhead lighting compositions.
Rental Companies
For inventory serving major productions that require the largest standard EVT290S circle.
Riggers and Engineers
For reviewed suspended or load-bearing configurations requiring multiple pick points.

Included Components

A Complete Eight-Piece Circle with Hardware for Every Arc.

The system is configured as eight 45-degree arc segments. Each arc includes its own set of conical connection hardware for joining it to the adjoining sections.

8x 45-Degree Arc Segments
Eight matching curved EVT290S truss sections create the full 360-degree circle.
32 Conical Couplers
Each of the eight arcs includes four couplers, for 32 couplers total, to align and join the mating truss chord ends.
64 Tapered Coupler Pins
Each of the eight arcs includes eight coupler pins, for 64 pins total, to secure the installed couplers.
64 R-Clips
Each of the eight arcs includes eight R-clips, for 64 R-clips total, to retain the installed coupler pins.
All eight arc joints are structural connection points.

Inspect and secure every active chord connection at every joint before lifting or loading the completed circle. Do not treat the ring as assembled until all required couplers, pins, and R-clips are installed and retained.

System Compatibility

Fits F34, EVT290S, and All Standard 290mm Square Truss Systems.

The EVT290S-C600 fits F34, EVT290S, and standard 290mm square truss systems using compatible conical connector geometry.

EVT290S Compatibility
Directly compatible with the EVT290S square aluminum truss series.
F34 Compatibility
Connects seamlessly with standard F34-style 290mm square truss straights and corners.
50 mm Clamp Compatibility
Main chords accept compatible 50 mm / 1.97 in clamps for mounting moving heads and fixtures.
Verify Before Mixing Brands
While F34 compatible, always test-fit connections with other brands on the ground before lifting.

Assembly Overview

Build the Circle on a Flat Surface. Then Lift Using an Engineered Plan.

Lay out all eight segments in their final circular orientation before installing the conical hardware. Confirm this dimension matches your design requirements before beginning assembly.

01 — Inspect Every Segment
Check chords, braces, welds, receivers, couplers, pins, and clips for damage or deformation.
02 — Lay Out the Circle
Place all eight 45-degree sections on a clean, level surface in final orientation.
03 — Install Couplers
Insert the correct conical couplers into the mating chord ends.
04 — Join Adjacent Segments
Bring each segment together without forcing the chord receivers out of alignment.
05 — Install Pins and R-Clips
Drive the tapered pins fully and secure each one with the correct retaining clip.
06 — Final Inspection
Confirm the circle is round, every joint is seated, and all hardware is properly retained before rigging.

Safety and Rigging

A 6-Meter Circle Requires Multiple, Carefully Planned Pick Points.

Circular truss loads must be calculated differently than straight spans. Always consult the load table for this specific diameter. When rigging from a circle this large, hanging points must be evenly spaced to prevent warping the frame, and a 6-meter circle requires multiple pick points.

Never exceed the rated load capacity of the completed circle.
Inspect every chord, brace, weld, receiver, coupler, tapered pin, and R-clip before use.
Ensure all couplers, pins, and R-clips are fully engaged and secured at every joint.
Do not place concentrated loads directly at a truss connection unless the engineering specifically allows it.
Distribute hanging points evenly around the ring to prevent warping the frame.
Use rated clamps, slings, shackles, hoists, and support hardware selected for the actual load case.
All overhead structures must be reviewed by a qualified rigger or structural engineer.
Assembly and lifting must be performed by trained personnel using an approved plan.
