Product Overview

Eight Matching Arcs Create One Complete 7-Meter Circle.

The EVT290S-C700 combines eight matching 45-degree curved truss arcs into a complete 7.0 m / 22.96 ft circular truss assembly. When all eight sections are joined, the ring provides a 6.42 m / 21.06 ft inside opening for a broad stage zone, convention exhibit, scenic composition, studio environment, lighting system, or project-specific technical installation. The same curved arc geometry also lets designers specify portions of the circle for custom structures. Whether the project uses one arc, a partial curve, or the complete ring, evaluate the resulting assembly as its own supported and loaded truss structure.

Complete 360-Degree Circle
Join all eight matching arcs to build one continuous 7.0 m / 22.96 ft circular truss ring.
45-Degree Arc Geometry
Each curved section represents 45 degrees of the completed circle, allowing planned curved configurations at consistent geometry.
6.42 m Clear Opening
The completed ring frames a 6.42 m / 21.06 ft interior area for large-scale overhead, scenic, exhibit, and production applications.
Compatible Square Truss System
The arcs use EVT290S / F34-format 290 mm square truss geometry and a conical connection system for approved system integration.

Arc Configurations

Build the Full Ring—or Use the Arcs for Custom Curved Truss Geometry.

The C700 is supplied as eight matching 45-degree arcs that form a complete circle. Those arcs can also be specified as curved components in custom EVT290S / F34 truss structures, subject to proper connection, support, loading, and engineering review. The number of arcs determines the total curve: one arc provides 45 degrees, two provide 90 degrees, four form a 180-degree half circle, and all eight form the full 360-degree ring.

01
One Arc — 45 Degrees
Use a single curved section as a controlled transition in a custom scenic frame, exhibit outline, entrance, or planned truss design.
02
Two Arcs — 90 Degrees
Create a quarter-circle curve for rounded corners, radial arrangements, exhibit boundaries, or curved overhead transitions.
03
Four Arcs — 180 Degrees
Build a half-circle frame for an arch, stage surround, curved backdrop, exhibit canopy, or open-ended overhead structure.
04
Eight Arcs — 360 Degrees
Assemble the complete 7.0 m / 22.96 ft circle for a full circular perimeter with a 6.42 m / 21.06 ft interior opening.
Every arc configuration is a different structural arrangement.

Do not apply completed-circle assumptions to a partial circle, arch, or custom assembly. Support locations, connections, fixtures, attachments, loads, and engineering requirements must be determined for the exact configuration being built.

What the Arcs Can Build

From Full Truss Rings to Arches, Curves, and Custom Scenic Structures.

The modular 45-degree arcs allow a single C700 geometry to serve full-circle and partial-curve projects. Use the complete ring where a continuous circular perimeter is required, or plan selected arcs into compatible truss structures when the design calls for a gradual turn, an open arch, a rounded boundary, or a radial form. Any use with lighting, video-related equipment, signage, graphics, scenic material, cable paths, or other attachments must be evaluated within the complete approved structure.

Full Circular Truss Rings
Create a 360-degree overhead or scenic ring for a large stage, convention exhibit, studio zone, installation, or designed event environment.
Partial Circles and Open Rings
Use selected arcs to create open-ended circular forms around a stage edge, exhibit area, product display, or planned audience-facing zone.
Large Truss Arches
Combine curved sections into half-circle or partial-curve arches for entrances, scenic portals, booth structures, canopies, and custom frames.
Rounded Exhibit Perimeters
Build curved exhibit outlines, branded boundaries, product-theatre surrounds, hospitality zones, and overhead graphic structures.
Curved Scenic Forms
Integrate arcs with compatible straight truss to form rounded backdrops, scenic walls, canopies, transition points, and architectural profiles.
Radial Truss Assemblies
Use multiple arcs in an engineered custom arrangement where a project requires circular, semi-circular, or radial truss geometry.

Included Components

A Complete Circle Package of Eight Matching 45-Degree Arcs.

The EVT290S-C700 complete circle package contains eight matching 45-degree curved arc sections. The complete ring requires connection hardware at each arc joint. The package is documented with thirty-two conical couplers, sixty-four tapered pins, and sixty-four R-clips for the full eight-arc assembly. Confirm the current package contents, the connection hardware condition, and all required project hardware before assembly.

8 × Curved Arc Sections
Eight matching 45-degree EVT290S / F34-format curved truss sections form the complete 360-degree C700 circle.
32 Conical Couplers
The complete-circle connection package includes conical couplers for joining the required chord receivers across the eight arc joints.
64 Tapered Pins
Tapered pins secure the installed couplers at the required chord connections of the complete circular assembly.
64 R-Clips
R-clips retain the tapered pins. Inspect and secure all required pins and retaining clips before moving, lifting, or loading the structure.
Connection hardware is structural hardware.

Every active connection must be fully seated, pinned, and retained. If arcs are configured differently than the complete circle, confirm the correct hardware, component orientation, and connection plan for that exact assembly.

System Compatibility

Use the C700 Arcs Within Compatible 290 mm Square Truss Systems.

The C700 arcs use 290 mm square truss geometry, 50 mm main chords, and a conical connection system. This permits integration with compatible EVT290S, F34, and matching 290 mm square conical truss components when receiver spacing, coupler dimensions, chord geometry, component orientation, and technical documentation all match. Integrating an arc with straight truss or another geometry changes the completed structure and must be reviewed for its actual supports, loading, and engineering requirements.

EVT290S Integration
Connect compatible EVT290S straight sections, corners, bases, and accessories to develop approved custom truss structures.
F34 Compatibility
Use matching F34 290 mm square truss geometry and conical connection hardware where verified dimensional interfaces align.
Straight-and-Curved Builds
Combine arcs and compatible straight components for rounded perimeters, arches, scenic forms, and other engineered custom structures.
50 mm Clamp Interface
The 50 mm main chords accept compatible professional clamps where their locations and loads are approved for the complete assembly.
A mechanical connection does not confirm a safe structural configuration.

Verify physical interfaces, manufacturer documentation, hardware requirements, and engineering suitability before combining components or hanging loads from any custom arc assembly.

Assembly Overview

Lay Out the Intended Curve, Verify Every Joint, Then Lift Under an Approved Plan.

The complete C700 circle weighs 296 lb / 134.3 kg and contains eight arc-to-arc joints. Build the intended assembly on a clean, level surface using trained personnel and current manufacturer instructions. For a full circle, place all eight arcs in final sequence before installing connection hardware. For a partial circle or custom structure, confirm the exact component order, orientation, support plan, and required end conditions before assembly. Never force a joint into alignment.

01 — Inspect Components
Inspect all chords, braces, welds, receivers, couplers, tapered pins, and R-clips before use.
02 — Plan the Exact Shape
Confirm whether the structure is a full circle, partial curve, arch, or custom build before arranging components.
03 — Lay Out the Arcs
Place the arcs on a clean, level surface in their final order and verify all receiver orientations.
04 — Install Connections
Install the correct conical couplers, tapered pins, and R-clips at all required chord connections.
05 — Inspect the Assembly
Confirm every joint is seated, pinned, retained, and aligned without forced correction or visible distortion.
06 — Approve for Use
Confirm the handling, support, rigging, and loading plan for the exact finished configuration before lifting or loading.

Safety and Engineering

Full Circles, Half Circles, and Arches Each Require Their Own Load Review.

A complete 7.0 m circle, a 180-degree arch, a 90-degree curve, and a custom straight-and-curved assembly do not behave as the same structure. Support-point quantity, support locations, end conditions, fixture positions, hardware condition, applied loads, dynamic forces, lateral restraint, and environmental exposure determine the resulting load case. Use current manufacturer documentation for the exact assembly and obtain qualified rigging and engineering review for overhead, load-bearing, outdoor, public-facing, or otherwise regulated structures.

Inspect every truss member, weld, receiver, coupler, tapered pin, R-clip, clamp, sling, and related connection component before use.
Confirm all active chord connections are fully seated, pinned, and retained before moving, lifting, suspending, or loading the assembly.
Do not use a completed-circle support or load assumption for a partial circle, arch, or mixed straight-and-curved structure.
Do not place concentrated loads at a connection or unsupported arc location unless explicitly approved for the exact load case.
Use rated, inspected rigging hardware and supports selected for the real configuration and all applied loads.
Evaluate wind, weather, public access, and all applicable environmental conditions for outdoor or exposed structures.
Have overhead and load-bearing assemblies reviewed by qualified rigging and engineering professionals before operation.
Assembly, lifting, modification, and strike must be performed by trained personnel following approved procedures.
