Functional Details

Purpose-Built Features for Handling, Connection, and Mounting.

The base plate combines a compact aluminum panel with a factory-attached half-coupler layout, an M12 threaded center hole, and an integrated carrying handle. Each feature supports installation and handling; the complete truss assembly still requires correct setup, full engagement, inspection, and project-specific stabilization where needed.

Factory-Attached Half Couplers

Four installed half couplers support one compatible standard 290 mm square truss connection.

Included Pins and R-Clips

Four coupler pins and four R-clips are included for retention of the compatible truss-to-plate connection.

M12 Threaded Center Hole

System Compatibility

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

The EVT290S-ABP12 uses 290 mm square truss geometry and a conical connection system. It fits compatible EVT290S, F34, and standard 290 mm square truss systems. The plate has four factory-attached half couplers and includes four coupler pins and four R-clips for connecting one compatible truss section. Confirm the actual truss receiver geometry, full conical seating, and installation of all four pins and R-clips before use.

EVT290S Compatibility

Connects to compatible EVT290S vertical truss sections and related 290 mm square components using the factory-attached half couplers.

F34 Compatibility

Compatible with F34 290 mm square truss geometry and matching conical receiver interfaces when the actual connection fits correctly.

Standard 290 mm Square Systems

Fits compatible standard 290 mm square truss systems using matching conical receiver geometry. Verify the physical interface before combining separately sourced or mixed-brand components.

Included Conical Hardware

The plate includes four factory-attached half couplers, four coupler pins, and four R-clips for one compatible truss-to-plate connection. Install and retain all four pins and R-clips before use.

Installation Sequence

Install the Base Plate in a Controlled, Verified Sequence.

The plate is one component of the assembly. Before use, verify the support surface or mounting location, plate condition, installed half couplers, included retention hardware, full truss seating, stability measures, and final inspection requirements for the completed structure.

01 — Inspect the Plate

Confirm the plate is flat, undamaged, and free of cracks, deformation, excessive wear, or compromised threads.

02 — Verify Hardware

Confirm all four factory-attached half couplers, four coupler pins, and four R-clips are serviceable and appropriate for the compatible connected truss system.

03 — Position the Plate

Place or mount the plate on a stable, level, and approved surface or mounting location.

04 — Connect the Truss

Seat one compatible truss section fully in the conical connection interface and secure all four included coupler pins and R-clips.

05 — Add Required Stability

Use ballast, anchoring, barriers, bracing, or another approved support method required for the complete structure and site.

06 — Final Inspection

Check alignment, full hardware engagement, stability, and attached fixtures before the structure enters service.

Safety and Stability

A Lightweight Plate Is Not a Substitute for Ballast or Anchoring.

The documented plate weight is 4 lb / 1.81 kg. That lightweight construction supports portability but does not provide substantial ballast by itself. The required stability measures depend on the vertical structure, center of gravity, height, attached equipment, lateral loading, wind exposure, support surface, public access, and site conditions. Select ballast, anchoring, bracing, barriers, or other support measures as required for the complete installation.

At 4 lb / 1.81 kg, this aluminum plate does not provide significant ballast by itself.

Do not rely on the plate alone for tall freestanding towers, arches, outdoor structures, wind-exposed builds, or structures with lateral or eccentric loads.

Use appropriate ballast, anchoring, bracing, barriers, or a different support solution where the completed structure requires additional stability.

Inspect plate flatness, factory-attached half couplers, M12 threads, included pins, R-clips, and connected truss components before every use.

Ensure all four included coupler pins and R-clips are fully installed and retained before loading or using the structure.

Use the M12 center hole only with compatible hardware and a reviewed load arrangement.

Installation must be performed by personnel familiar with truss assembly, hardware retention, and ground-support practices.

Obtain qualified review where required by the structure, venue, local authority, attachment method, or operating conditions.
