Included Connection Hardware

Four Hardware Sets for the Complete Truss Circle.

The EVT290S-C400 includes four connecting-hardware sets for assembly of the complete truss circle. Together, the included hardware provides sixteen conical couplers, sixteen tapered pins, and sixteen R-clips for the four matching 90-degree arc sections. Confirm the current product package and all required hardware before assembly.

Four Hardware Sets
One connecting-hardware set is included for each of the four matching 90-degree arc sections.
16 Conical Couplers
The included hardware provides the conical couplers required to connect the four arc sections into the complete circle.
16 Tapered Pins
The included tapered pins secure the installed couplers at the required chord connections.
16 R-Clips
The included R-clips retain the installed tapered pins. Confirm every pin has its required R-clip before the circle is lifted, moved, or loaded.
All four arc joints are structural connection points.

Inspect and secure every active chord connection at every joint before lifting or loading the completed circle. The ring is not fully assembled until all required couplers, pins, and R-clips are installed and retained.

System Compatibility

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

The EVT290S-C400 uses 290 mm square truss geometry, 50 mm main chords, and a conical connection system. Combining it with other components requires matching receiver spacing, coupler dimensions, chord geometry, component orientation, and applicable engineering data. A nominal mechanical fit does not establish structural compatibility or equivalent capacity. Individual arc use changes the structural system and must be evaluated for its actual supports, attachments, and loading condition.

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.
Individual Arc Integration
A 90-degree arc may be specified with compatible straight sections and junctions as part of an approved curved truss structure.
Circle-Specific Loading
Evaluate the complete ring or an individual-arc structure according to its actual supports, attachments, and load locations.
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 supports transport and handling, but every chord must align correctly at each joint before the completed circle is lifted, supported, rigged, or loaded. Use trained personnel, adequate clear floor space, and appropriate handling methods for the 156 lb / 70.76 kg completed assembly. When an arc is used individually, follow the approved assembly and support plan for the complete curved structure.

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 or individual-arc structure, support or suspension points, load locations, connection condition, bracing, orientation, dynamic forces, lateral forces, environmental conditions, and applicable engineering documentation. Do not apply straight-truss span capacities directly to the 4.0 m circular assembly or to an individual arc.

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.
Determine support locations, suspension methods, and equipment loads using the actual completed circle or individual-arc structure.
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.
