Product Overview

A Compact 360-Degree Structural Form Built from Two Matching Arcs.

Unlike straight truss or individual corner sections, the EVT290S-C150 is designed around a completed circular geometry. Two 180-degree sections join to form a 1.5-meter-diameter ring, providing a symmetrical structural perimeter for lighting, scenic, display, and technical applications.

Complete Circular Geometry
Two matching semicircular sections combine to create one continuous 360-degree truss ring.
Compact 1.5 m Diameter
The relatively small footprint is useful where a circular feature is required without the size of a large arena or stage truss ring.
Two-Piece Construction
Dividing the circle into two 180-degree arcs simplifies handling, transportation, storage, and on-site assembly.
Square-Truss Cross Section
The circular path retains the four-chord square-truss construction used throughout compatible EVT290S and F34-style assemblies.

Common Applications

Circular Geometry Creates Different Design Possibilities Than Straight Truss.

The C150 is best understood as a structural shape rather than simply another truss length. A circular perimeter provides consistent radial positioning around a central point, making it useful for equipment, lighting, signage, scenic elements, and visual installations.

01
Circular Lighting Features
Fixtures can be distributed around the perimeter to create symmetrical overhead lighting or radial illumination patterns.
02
Trade Show Displays
Use the circle as an overhead feature, suspended branding element, focal point, or compact exhibit structure.
03
Scenic Installations
The geometry can form rings, halos, portals, suspended scenic elements, or other circular visual forms.
04
Studio & Production Environments
Circular positioning can support cameras, practical lighting, sensors, or equipment arranged around a central subject or working area.
05
Retail & Branded Environments
A compact truss ring can define a product zone, display area, activation space, or branded overhead feature.
06
Custom Technical Structures
The continuous radial perimeter can support specialized layouts where equipment needs to be positioned around a common centerline.

Who It’s For

For Projects Where the Shape of the Truss Is Part of the Design.

The EVT290S-C150 is intended for users who need a compact circular framework rather than a conventional linear span or rectangular perimeter.

Lighting Designers
For symmetrical fixture placement and suspended circular lighting compositions.
Exhibit Designers
For distinctive overhead structures that visually separate a booth from conventional square and rectangular designs.
Scenic Designers
For ring-shaped scenic forms, portals, suspended features, and architectural elements.
Production Companies
For temporary lighting, AV, branded, and event installations requiring circular geometry.
Technical Integrators
For camera, sensor, display, simulation, and specialized equipment layouts arranged around a central area.
Fabrication Departments
For modular projects where a pre-defined circular truss form reduces the need to approximate curves with multiple angled corners.

Assembly Configuration

Two 180-Degree Arc Sections Form the Complete Circle.

The system is configured as two semicircular structural sections. The mating ends are connected using compatible conical hardware to close the ring and establish the final circular geometry.

2 × 180° Arc Sections
The matching semicircular sections create the full 360-degree truss circle.
Conical Couplers
Couplers align and mechanically join the corresponding chord receivers at each arc connection.
Pins & R-Clips
Tapered pins secure the couplers and R-clips retain the installed pins.
Both arc joints are structural connection points.

Inspect and secure every chord connection at both interfaces before lifting or loading the completed circle. The ring should not be treated as fully assembled until all required connection hardware is installed and retained.

System Compatibility

Designed Around EVT290S and F34-Compatible Connection Geometry.

The C150 follows the connection architecture associated with compatible EVT290S and F34-style square truss. When integrating the circle with additional structural components, confirm chord spacing, receiver dimensions, connector geometry, and engineering requirements for the actual system being used.

EVT290S Integration
The circle is designed around the EVT290S square-truss geometry and conical connection format.
F34-Type Systems
The source identifies compatibility with F34 and other standard systems sharing the required dimensional interface.
Clamp Interface
The 50 mm main chords provide the common tube diameter used by many professional truss clamps and mounting accessories.
Circle-Specific Loading
A curved structure should be evaluated according to its actual support arrangement and load locations rather than using straight-span assumptions.
Nominal compatibility does not replace structural verification.

Matching F34-type geometry may allow components to connect mechanically, but the allowable capacity of the completed installation depends on the specific truss, support arrangement, connection condition, and engineering data.

Assembly Overview

Join the Two Semicircular Sections Before Rigging the Completed Ring.

The two-piece design simplifies transportation, but both arc sections must be correctly aligned before the ring functions as the intended circular assembly. The most important assembly consideration is maintaining alignment across all four chords at each semicircle connection.

01 — Inspect Both Arcs
Check chords, bracing, welds, receivers, and connection hardware for damage before joining the sections.
02 — Position the Semicircles
Place the two 180-degree sections in their intended orientation and align the corresponding ends.
03 — Install Couplers
Insert compatible conical couplers at the mating chord receivers.
04 — Close the Ring
Bring both interfaces together gradually while keeping the four chord connections aligned.
05 — Secure the Hardware
Fully install tapered pins and R-clips at every required connection.
06 — Verify Circular Alignment
Inspect both joints and confirm the completed ring is correctly aligned before lifting or applying equipment loads.

Safety & Engineering

A Circular Truss Has Different Load Behavior Than a Straight Span.

The structural performance of the EVT290S-C150 depends on how the completed ring is supported and loaded. A circle suspended from multiple points behaves differently from a ring supported from one or two locations, and equipment placed around the circumference can produce non-uniform load conditions.

Inspect both arc sections, welds, braces, chords, receivers, couplers, pins, and R-clips before each installation.
Confirm every connection at both semicircle joints is completely seated and retained.
Determine support locations and equipment loads using the actual completed circular configuration.
Do not assume straight-truss span capacities apply directly to a circular structure.
Account for concentrated loads, uneven fixture distribution, dynamic forces, and the number and position of suspension points.
Outdoor use requires consideration of wind and other applicable environmental loads.
A complete suspended or ground-supported structure should be reviewed against applicable engineering documentation.
Use qualified personnel for truss assembly, rigging, lifting, and load placement.

Product Questions

Frequently Asked Questions

Is the EVT290S-C150 a complete circle or a single arc?

The complete C150 circle is configured from two matching 180-degree arc sections. When connected, the two sections form a full 360-degree ring.

What is the actual size of the completed circle?

The completed structure has a listed outside diameter of 1.5 m / 4.92 ft and an inside diameter of 0.92 m / 3.02 ft.

Why use a truss circle instead of multiple angled corners?

A purpose-built circular truss produces a continuous curved perimeter rather than approximating a circle with multiple straight sections and corner nodes. This can provide cleaner visual geometry and more consistent radial equipment placement.

Can lighting fixtures and equipment be mounted around the circle?

Yes, when compatible mounting hardware is used and the fixture positions, support points, and total loading are within the requirements of the engineered structure.

Can straight-truss load tables be used for this circle?

They should not automatically be treated as equivalent. Circular structures have different geometry and support conditions, so allowable loading should be evaluated using data applicable to the actual ring configuration.
