EVT290S-C150 4.92-Foot Truss Circle.
A Two-Piece Circular Truss Assembly for F34 and 290 mm Square Truss Systems.
The EVT290S-C150 is a complete circular aluminum truss assembly with a 1.5 m / 4.92 ft outside diameter. Two matching 180-degree arc sections join to form one continuous 360-degree truss circle. The C150 provides a defined circular truss assembly for lighting, display, scenic, branded, studio, and technical installations where the approved truss system calls for a circular form.
Product Facts
Product Overview
A Complete Circular Truss Assembly Built from Two Matching Arc Sections.
Unlike a straight truss section or a fixed-angle corner, the EVT290S-C150 is supplied as a complete truss circle. Two matching 180-degree sections join at two arc joints to form a 1.5 m / 4.92 ft outside-diameter ring. Select this assembly where the approved truss system requires a circular truss form rather than a straight or angular connection.
Common Applications
Add a Circular Truss Form to Lighting, Display, Scenic, and Technical Installations.
The EVT290S-C150 provides a continuous circular perimeter around a central area. Select it when the approved truss system calls for equipment, scenic elements, branding, lighting, displays, cameras, sensors, or other technical components to be arranged around a circular form. The complete approved truss system determines support locations, hardware, load placement, attachment methods, and required engineering review.
Circle Configuration
Two 180-Degree Arc Sections Form the Complete Truss Circle.
The EVT290S-C150 is supplied as two matching semicircular arc sections. The arc ends connect at two separate joints to close the circle. Both joints are required connection points in the completed truss assembly and must be fully aligned, secured, and inspected before the circle is lifted, supported, or loaded.
Included Connection Hardware
Two Hardware Sets Included with the Complete Truss Circle.
The EVT290S-C150 includes two connecting-hardware sets for assembly of the complete truss circle. Together, the included hardware consists of eight conical couplers, sixteen tapered pins, and sixteen R-clips. Confirm the current product package, approved truss system, and connection schedule before assembly.

System Compatibility
EVT290S, F34, and 290 mm Square Truss Systems.
The EVT290S-C150 follows the 290 mm square-truss profile and conical connection format associated with the EVT290S and F34 product families. System fit requires more than matching nominal outside dimensions. Confirm chord spacing, receiver dimensions, conical connector details, component orientation, connection hardware, support arrangement, and applicable structural data before combining separately sourced components.
Assembly Overview
Join the Two Semicircular Sections Before the Completed Circle Is Rigged or Loaded.
The two-piece design supports transportation and handling, but both arc sections must be correctly aligned before the circle functions as the intended completed assembly. Maintain alignment across all four chords at each arc joint and verify every required connection before lifting, supporting, rigging, or loading the truss circle.
Safety and Engineering
A Circular Truss Assembly Is Not a Standalone Load, Span, or Suspension Rating.
The structural performance of the EVT290S-C150 depends on how the completed circle is supported and loaded. Support from multiple points differs from support at one or two locations, and equipment placed around the circle can produce uneven load conditions. Determine suitability from the complete approved truss system, including support locations, connection hardware, rigging method, attachment points, applied loads, fixture distribution, bracing, environmental conditions, venue requirements, and applicable approvals.
Product Questions
EVT290S-C150 Frequently Asked Questions.
Is the EVT290S-C150 a complete circle or a single arc?
The C150 is a complete truss circle supplied as two matching 180-degree arc sections. When both arc joints are connected, the sections form a continuous 360-degree truss circle.
Why select a truss circle instead of multiple angled corners?
A purpose-built truss circle provides a continuous circular form rather than approximating a circle with multiple straight sections and corner components. Select it when the approved truss system calls for a 1.5 m circular assembly.
Can lighting fixtures and equipment be mounted around the circle?
Equipment may be mounted only when matching mounting hardware is used and the fixture positions, attachment points, support arrangement, and total loading have been evaluated for the complete approved truss system.
Can straight-truss load tables be used for this circle?
Do not automatically treat straight-truss data as a rating for the C150. The completed circle must be evaluated for its actual support arrangement, attachment points, and load locations.
