Exhibit and Brand Teams
For larger booths, branded environments, product demonstrations, and overhead exhibit structures.
Stage and Scenic Teams
For circular scenic construction, stage surrounds, backdrops, portals, and production environments.
Lighting and Video Teams
For approved fixture, video, and technical-equipment placement around a central installation area.
Studio and Technical Teams
For controlled production, camera, sensor, motion-capture, and technical installations requiring circular geometry.

System Configuration

Four 90-Degree Arc Sections Form the Complete Truss Circle.

The C300 is supplied as four matching quarter-circle sections. The arc ends connect at four joints to close the circle. Each joint requires the specified conical connection hardware. Confirm every coupler, tapered pin, and R-clip is correctly installed and retained before the circle is lifted, supported, rigged, or loaded.

4 × 90-Degree Arc Sections
Four matched arc sections form the complete 360-degree circle when assembled in sequence.
Conical Couplers
Conical couplers align and mechanically connect the adjoining chord receivers at every joint.
Tapered Pins and R-Clips
Tapered pins secure the couplers and R-clips retain the installed pins at every required chord connection.
Ground Assembly
The four-piece configuration allows the complete circle to be inspected for alignment and closure before elevation.
Verify natural closure before lifting.

At a 3.0 m diameter, do not force the final joint to close. Inspect component orientation, receivers, connectors, and alignment if the arc ends do not meet naturally. Do not use damaged or incompatible components to complete the circle.

System Compatibility

EVT290S, F34, and 290 mm Square Truss Systems.

The C300 follows the 290 mm square-truss profile and conical connection format used by EVT290S and F34-format systems. Matching nominal dimensions alone do not establish structural equivalence. Before combining separately sourced components, confirm chord spacing, receiver dimensions, conical connector geometry, component orientation, hardware, support arrangement, and the engineering requirements for the complete installation.

EVT290S System
The C300 uses the EVT290S square-truss profile and its associated conical connection format.
F34 System
The product is listed for F34-format 290 mm square-truss systems with matching connection details.
Other 290 mm Systems
Dimensionally similar 290 mm conical systems require direct mechanical-interface verification before use.
Mixed-System Review
Evaluate the completed structure according to its actual supports, attachments, load locations, and current system documentation.
Physical fit does not establish structural equivalence.

A component may physically connect to another 290 mm truss component without the complete structure having equivalent strength, connection behavior, or approved load capacity. Verify the complete system before use.

Assembly Overview

Build the Circle on the Ground and Verify Closure Before Lifting.

Ground assembly provides room to position the four arc sections, inspect all connection points, and verify the final closure of the 3.0 m circle before elevation. The complete assembly weighs 124 lb / 56.24 kg; plan handling and assembly with trained personnel and appropriate equipment for the actual work conditions.

01 — Position the Four Arcs
Place the matching 90-degree sections in their intended orientation with sufficient floor area for the 9.84 ft completed circle.
02 — Inspect Components
Check chords, bracing, welds, receivers, couplers, tapered pins, and R-clips before joining any sections.
03 — Connect Sequentially
Install the specified conical couplers at the mating chord receivers and join the sections in sequence.
04 — Close the Final Joint
Confirm that the final receivers align naturally without forcing the completed circle out of its intended geometry.
05 — Secure Hardware
Fully seat the required tapered pins and install the required R-clips at every chord connection.
06 — Inspect Before Use
Verify circular alignment, connection security, attachments, support arrangement, and lifting method before elevation or loading.

Safety and Engineering

A 3-Meter Truss Circle Is Not a Standalone Load, Span, or Suspension Rating.

Circular truss must be evaluated as a completed assembly, not as four independently rated arc sections. Its suitability depends on support locations, suspension points, attached equipment, connection condition, load distribution, dynamic forces, environmental conditions, rigging method, and how the circle is incorporated into the complete approved truss system. Use load documentation specific to the 3.0 m circle; do not apply straight-truss data or assume performance from smaller circles.

Inspect chords, diagonal bracing, welds, receivers, conical couplers, tapered pins, and R-clips before every assembly.
Do not use a section with permanent deformation, cracked welds, damaged receivers, or other structural defects.
Confirm that every required connection is fully seated and retained before the completed circle is moved, lifted, supported, rigged, or loaded.
Determine support points and equipment loads from the actual completed circle and the approved complete truss system.
Account for concentrated loads, uneven fixture distribution, cabling, accessories, dynamic effects, and all other attached loads.
For overhead work, use a qualified rigger or structural engineer to review the planned suspension and loading condition.
Confirm venue, regulatory, and project-specific approval requirements before installation.
