How does the matte black powder coat hold up to frequent event use?"

The EVT290S-BBP12 features a highly durable, baked-on matte black powder coat designed to resist chipping and scratching during regular transport. To maintain its pristine stealth look for high-end events and floral displays, we recommend using protective transport bags or custom road cases between uses.

What hardware do I need to mount my variant truss system to this base plate?

To attach your square truss to this base plate, you will need four half-conical connectors, which secure to the plate using countersunk bolts from underneath. Once the half-conicals are installed, simply use standard tapered pins and R-clips to lock your vertical truss segments safely into place.

Studio and Stage Sets

For low-reflection truss columns and support structures where a silver aluminum finish would be visually distracting.

Floral and Decorative Displays

For decorative black-truss columns and event structures that are separately ballasted, anchored, or otherwise stabilized as required.

Top-Mount Applications

Use as a top plate where the approved system design requires a compatible mounting surface and verified load arrangement.

Functional Details

Compact Construction with Low-Reflection Black Finish.

The base plate combines a 12 x 12 in aluminum panel with a conical connection interface for one compatible truss section. Its matte black powder coat is an appearance feature for black truss layouts; it does not alter structural capacity or installation requirements. The connection hardware supports the truss-to-plate connection but does not independently establish allowable height, loading, ballast, anchoring, wind suitability, or stability for the completed structure.

Conical Connection Layout

Provides the compatible conical interface for one 290 mm square truss-to-plate connection.

Compact Contact Area

The 12 x 12 in footprint suits approved portable, display, and finish-sensitive installations.

Low-Profile Plate

The documented 0.23 in / 6 mm plate thickness provides a compact profile for compatible bottom or top mounting use.

Matte Black Powder Coat

Supports visual continuity in black truss, stage, studio, concert, exhibit, and other low-glare environments.

System Compatibility

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

The EVT290S-BBP12 uses 290 mm square truss geometry and a conical connection system. It fits compatible EVT290S, F34, and standard 290 mm square truss systems with matching receiver spacing and conical interface geometry. Confirm the actual truss receiver geometry, full conical seating, and full installation of the required connection hardware before use.

EVT290S Compatibility

Connects to compatible EVT290S vertical truss sections and related 290 mm square components.

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.

Connection Verification

Confirm actual receiver geometry, full conical seating, pin engagement, and retention before placing the completed structure into service.

Installation Planning

Assembly Requirements for Ground-Supported or Top-Mount Use.

The plate is one component of the assembly. Before use, verify the support surface or mounting location, plate condition, connection hardware, full truss seating, stability measures, and final inspection requirements for the completed structure. Handle the matte black finish carefully to reduce cosmetic damage during transport and installation.

01 — Inspect the Plate

Confirm the plate is flat and free from cracks, bends, deformation, or damaged connection points.

02 — Verify Compatibility

Confirm receiver spacing, conical interface geometry, and engineering data for the connected truss system.

03 — Verify Hardware

Confirm the factory-attached half couplers, included coupler pins, and included r-clips are serviceable before assembly.

04 — Position the Truss

Align the compatible truss section without forcing or misaligning the conical connection.

05 — Secure the Connection

Seat the truss fully and install all required connection hardware before applying load or placing the structure in service.

06 — Stabilize and Inspect

Add ballast, anchoring, outriggers, bracing, barriers, or engineered support as required, then inspect alignment, hardware engagement, stability, and installed loads.

Safety and Stability

A Lightweight Truss Base Plate Still Requires Ballast, Anchoring, and Engineering.

The documented plate weight is 4 lb / 1.81 kg. Its compact 12 x 12 in footprint does not independently establish safe height, load capacity, ballast, anchoring, wind suitability, or stability for a completed structure. The required support measures depend on the truss height, center of gravity, attached equipment, lateral loading, wind exposure, support surface, public access, and site conditions.

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

Do not rely on the plate alone to stabilize tall towers, arches, goal posts, outdoor structures, wind-exposed builds, or structures with lateral or eccentric loads.

Use appropriate ballast, anchoring, outriggers, bracing, barriers, or engineered support for the final structure.

Do not support loads directly from truss connection points unless the complete configuration is designed and approved for the actual load arrangement.

Inspect the plate, half couplers, coupler pins, r-clips, and connected truss before every use. Remove bent, cracked, deformed, or damaged components from service.

Account for dynamic, transverse, and environmental forces, including wind loads, in the complete structural plan.

Assembly should be completed by trained truss personnel and reviewed by a licensed professional engineer where required.
