Truss Compatibility

Designed for EVT290S, EVT12S, EVT20S, F34, and Standard 290 mm Square Truss Systems.

Use the included conical connector with the matching truss connection. Confirm system geometry, loading, ballast, and engineering before installation.

EVT290S
Compatible with the EVT290S 290 mm square conical truss series.
EVT12S
Listed for use with compatible EVT12S square aluminum truss configurations.
EVT20S
Listed for use with compatible EVT20S square aluminum truss configurations.
F34 and Standard 290 mm Systems
Compatible with matching F34 and standard 290 mm square truss connection geometry.

Assembly Overview

Position the Base. Connect, Secure, and Verify Stability.

01 — Inspect the Plate
Check the steel plate, handle, finish, connector, pin, and R-clip for damage.
02 — Position on a Level Surface
Place the plate on a clean, stable, load-bearing floor or platform.
03 — Install the Coupler
Confirm the conical coupler is correctly seated in the plate connection.
04 — Connect the Truss
Lower the compatible truss section onto the connector without forcing alignment.
05 — Install Pin and R-Clip
Fully seat the tapered pin and secure it with the R-clip.
06 — Verify the Complete Structure
Check plumb, stability, ballast, attached loads, and clearances before use.

Safety and Engineering

Base Weight Alone Does Not Define the Structure’s Allowable Capacity.

Final stability depends on truss height, attached loads, load direction, ballast, floor conditions, structure geometry, and project-specific engineering.

Do not exceed the allowable capacity of the complete base, truss, connection, and support system.
Do not suspend loads from the truss connection point on the base plate.
Inspect the plate and all connection hardware before every use.
Remove damaged or defective components from service and clearly label them DO NOT USE.
Do not drop, drag, or stack base plates without suitable protection.
Ensure every coupler, tapered pin, and R-clip is correctly installed before use.
All structures require review by a qualified professional engineer.
