EVT290S System Knowledge Center
A 29.52-Foot Circular Truss.
A 9-Meter Structural Circle for Production, Capture, and Display Systems.
The EVT290S-C900 is a 29.52 ft / 9.0 m square aluminum truss circle built from twelve 30-degree arc segments. Its 9.0 m outer diameter provides a circular structural perimeter for production, motion capture, XR, automotive, drone, lighting, display, and architectural installations. It uses the EVT290S 290 mm square-truss profile, EN AW-6082 T6 aluminum alloy construction, and a brushed aluminum finish.
Product Facts
Product Overview
Twelve Matching Arcs Form One Complete 9-Meter Circle.
The EVT290S-C900 creates a complete 9.0 m diameter circle using twelve identical 30-degree arc segments and a conical truss connection system.
Common Applications
A Large Circular Perimeter for Production, Capture, Testing, and Display Systems.
The EVT290S-C900 provides a repeatable 9.0 m circular structural perimeter with distributed mounting positions around a common center. This geometry can support layouts that position equipment, cameras, sensors, lighting, or displays around a central subject, vehicle, aircraft, object, or performance area.
Who It’s For
For Teams That Need A 9-Meter Circular Working Envelope.
The EVT290S-C900 is intended for trained teams planning a 29.52 ft / 9.0 m circular truss system around larger subjects, working zones, and multi-position technical layouts. Its 27.62 ft / 8.42 m inner opening can accommodate broader camera geometry, wider lighting placement, vehicle-scale displays, simulation zones, and other applications that need substantial central clearance.
Included Components
A Complete Twelve-Piece Circle with Hardware for Every Arc.
The EVT290S-C900 is configured as twelve 30-degree arc segments. The product source confirms a conical connection system using couplers, tapered pins, and R-clips. Confirm the exact shipped hardware count with the sales order or packing documentation before installation.
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 Standard 290 mm Square Truss Systems.
The product source identifies compatibility with F34, EVT290S, and standard 290 mm square truss systems using compatible conical connector geometry.
Assembly Overview
Build the Circle on a Flat Surface. Then Lift Using an Engineered Plan.
Lay out all twelve segments in their final circular orientation before installing the conical hardware. Confirm the 29.52 ft / 9.0 m outer diameter matches the approved design before assembly.
Safety and Rigging
A 9-Meter Circle Requires a Carefully Calculated Rigging Plan.
Circular truss loads must be calculated differently than straight spans. Consult the load tables for this specific diameter. The product source specifies evenly spaced hanging points and a carefully calculated, multiple-pick-point plan to help prevent frame warping.
Product Questions
Frequently Asked Questions
How large is the EVT290S-C900 circle?
Its outer diameter is 29.52 ft / 9.0 m, and its inside diameter is 27.62 ft / 8.42 m.
How many sections make the complete circle?
Twelve 30-degree arc segments form the complete 360-degree circle.
How much does the complete circle weigh?
The product source documents a weight of 334 lb / 151.5 kg.
What connection hardware does it use?
It uses a conical connection system with couplers, tapered pins, and R-clips. Verify exact shipped hardware quantities against the sales order or packing documentation.
What truss systems are compatible?
The source identifies F34, EVT290S, and standard 290 mm square truss compatibility, plus 50 mm / 2 in clamp compatibility for moving heads and fixtures.
Can the circle be suspended?
A suspended configuration requires a diameter-specific load review and a carefully calculated plan with multiple, evenly spaced pick points. A qualified rigger or engineer must review the complete overhead structure.
