Product Overview

A Large 360-Degree Structural Form Built from Four Matching 90-Degree Arcs.

The EVT290S-C400 creates a 4 m / 13.12 ft circular truss perimeter for projects where a large radial form is preferred over straight truss runs, angled corners, or rectangular grids.

Complete Circular Geometry
Four matching 90-degree arc sections connect to form one continuous 360-degree truss ring.
4 m Outer Diameter
Creates a substantial 13.12 ft outer-diameter feature for overhead, scenic, exhibit, and stage applications.
Four-Piece Construction
Quarter-circle arcs simplify handling, transport, storage, and assembly compared with a one-piece ring.
290 mm Square Profile
Uses four-chord square-truss geometry with 50 mm main chords and a conical connection system.

Common Applications

Designed for Large Circular Lighting, Scenic, Exhibit, and Stage Structures.

A circular perimeter positions equipment and visual elements around a common centerline, enabling layouts that are difficult to reproduce with standard straight truss sections.

01
Circular Lighting Rigs
Supports approved fixture layouts arranged around a symmetrical overhead circular perimeter.
02
Stage and Concert Features
Creates a prominent circular truss element for stage sets, lighting concepts, and scenic environments.
03
Trade Show Displays
Forms overhead booth landmarks, circular branding features, entrances, and focal-point structures.
04
Scenic Rings and Portals
Provides a purpose-built circular framework for halos, portals, suspended scenery, and custom visual installations.
05
Studio and Broadcast Environments
Supports approved lighting, camera, display, and production layouts around a central set or subject area.
06
Retail and Branded Spaces
Defines activation zones, product displays, and branded overhead environments with a large circular form.

Who It’s For

For Teams Building Large-Format Circular Truss Structures.

The EVT290S-C400 is suited to professional users who need a 4 m circular structural perimeter within a compatible 290 mm square truss system.

Lighting Designers
For symmetrical fixture placement and circular lighting compositions.
Event Production Companies
For concert, corporate, touring, and temporary event structures with circular geometry.
Exhibit Builders
For booth structures and overhead features that distinguish a display from conventional rectangular layouts.
Scenic Designers
For ring-shaped scenery, portals, suspended elements, and architectural features.
Rental Companies
For inventory programs requiring a reusable large-format circular truss option.
Technical Integrators
For specialized camera, display, simulation, sensor, and equipment layouts around a central area.

Included Connection Hardware

Four Arc Sections with Hardware for Each Connection Interface.

The complete circle consists of four 90-degree arc sections. Each arc includes the conical hardware used to connect it with a compatible adjoining arc or truss component.

4 × 90° Arc Sections
Four matching quarter-circle sections create the completed 360-degree truss ring.
16 Conical Couplers
Each of the four arc sections includes four couplers for compatible conical connections.
16 Coupler Pins
Each arc includes four tapered coupler pins for securing the installed couplers.
16 R-Clips
Each arc includes four retaining clips to secure the installed coupler pins.
All four completed 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

EVT290S, F34, and Matching 290 mm Square Conical Truss Systems.

The EVT290S-C400 uses 290 mm square truss geometry, 50 mm main chords, and a conical connection system. Compatibility with other components requires matching receiver spacing, coupler dimensions, chord geometry, and engineering data.

EVT290S Compatibility
Designed to integrate with compatible EVT290S square truss sections, corners, bases, and accessories.
F34 Compatibility
Compatible with matching F34 290 mm square geometry and conical hardware when dimensional interfaces match.
50 mm Clamp Interface
The 50 mm main chords accept compatible professional truss clamps where placement and loading are approved for the completed structure.
Circle-Specific Loading
Evaluate the ring according to its actual suspension or support arrangement and load locations rather than straight-span assumptions.
Nominal mechanical fit does not establish structural compatibility.

Before combining brands or systems, verify connector dimensions, receiver spacing, chord geometry, applicable manufacturer documentation, and engineering suitability for the completed installation.

Assembly Overview

Join Four 90-Degree Arcs in a Controlled, Verified Sequence.

The four-piece configuration improves handling and transport, but every chord must align correctly at each joint before the completed ring is lifted, rigged, or loaded.

01 — Inspect All Components
Inspect every arc, chord, brace, weld, receiver, coupler, pin, and R-clip for damage, wear, or deformation.
02 — Lay Out the Arcs
Place the four 90-degree sections on a clean, level surface in their intended circular orientation.
03 — Confirm Arc Orientation
Align corresponding arc ends and verify the completed 360-degree geometry before installing hardware.
04 — Install Couplers
Insert compatible conical couplers into the mating chord receivers at each required joint.
05 — Seat Pins and R-Clips
Fully install every tapered coupler pin and secure it with its retaining R-clip.
06 — Final Inspection
Confirm four-chord alignment, complete hardware engagement, support locations, and the approved load plan before use.

Safety and Engineering

Circular-Truss Capacity Depends on The Complete Supported Structure.

The EVT290S-C400 does not establish a stand-alone allowable load. Structural performance depends on the completed circular configuration, support or suspension points, load locations, connection condition, bracing, orientation, dynamic forces, and applicable engineering documentation.

Inspect all arc sections, chords, braces, welds, receivers, couplers, pins, and R-clips before every installation.
Confirm every connection at all four arc joints is fully seated, pinned, and retained before lifting or applying load.
Do not assume straight-truss span capacities apply directly to a circular ring.
Determine support locations, suspension methods, and equipment loads using the actual completed circular configuration.
Account for concentrated loads, uneven fixture distribution, dynamic forces, lateral forces, and the number and position of support points.
Do not use cracked, bent, deformed, heavily worn, or otherwise damaged components.
Outdoor installations require evaluation of wind and other applicable environmental loads.
Assembly, rigging, lifting, and load placement must be performed by qualified personnel and reviewed by an engineer where required.
