System Compatibility

EVT290S, F34, and Standard 290 mm Square Truss Systems.

EVT290S-Geyser uses 290 mm square truss geometry, 50 mm main chords, and a matching conical connection system. Compatibility requires matching receiver spacing, coupler dimensions, and engineering data.

EVT290S Compatibility

Integrates with compatible EVT290S straight sections, angled corners, junctions, and expansion components.

F34 Compatibility

Compatible with matching F34 290 mm square truss geometry and conical hardware.

Standard 290 mm Square Systems

Verify receiver spacing, connection geometry, and engineering data before combining systems.

50 mm Clamp Compatibility

Main chords accept properly rated standard 50 mm / 2 in clamps.

Assembly Sequence

Build the Octagon in a Controlled Ground-Level Sequence.

The source states that two people familiar with truss structures can assemble the system using a steel hammer. Additional assistance may be appropriate for lifting and final positioning.

01 — Lay Out Components

Arrange straight sections, angled corners, bases, and connection hardware in the intended octagon layout.

02 — Inspect Every Part

Remove damaged truss, couplers, pins, R-clips, or base components from service.

03 — Assemble the Upper Frame

Connect the angled top sections at ground level using the complete conical hardware set.

04 — Build the Lower Supports

Assemble the side sections and bases while maintaining matching geometry on both sides.

05 — Raise and Connect

Use a controlled method appropriate for the system weight and final installation plan.

06 — Final Inspection

Confirm every pin, R-clip, base condition, attachment, and stability measure before use.

Safety and Engineering

Evaluate the Octagon Arch as A Complete Installed Structure.

Do not exceed the allowable load capacity of the complete EVT290S-Geyser configuration.

Distribute applied loads equally between the appropriate main chords.

Do not apply concentrated loads directly at truss connections unless specifically approved.

Include lighting, signage, graphics, floral materials, clamps, cables, and decorative elements in the total applied load.

Use ballast or anchoring appropriate for the final configuration, attached surfaces, wind exposure, and installation site.

Inspect every truss section, angled corner, base component, coupler, tapered pin, and R-clip before use.

Assembly should be completed only by personnel familiar with trussing techniques.

A licensed professional engineer must review the final structure and loading where required.
