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.

System Compatibility

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

EVT290S-BBP12 uses 290 mm square truss geometry and a matching conical connection system. Compatibility requires matching receiver spacing, coupler dimensions, and engineering data.

EVT290S Compatibility

Integrates with compatible EVT290S straight sections and related 290 mm square 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.

Conical Hardware Compatibility

Use matching half-conical receivers, tapered pins, and R-clips approved for the connected truss system.

Installation Planning

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

01 — Inspect the Plate

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

02 — Install the Receivers

Secure four compatible half-conical connectors using the correct countersunk mounting hardware.

03 — Verify Compatibility

Confirm receiver spacing, coupler dimensions, truss geometry, and engineering data.

04 — Connect the Truss

Seat the truss fully and secure all tapered pins and R-clips.

05 — Stabilize the Structure

Add ballast, anchoring, outriggers, or engineered support according to the final design.

06 — Final Inspection

Check alignment, connection engagement, stability, and all installed loads before use.

Safety and Stability

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

At approximately 4 lb, this aluminum plate does not provide significant ballast by itself.

Do not rely on the plate alone to stabilize tall towers, arches, goal posts, or wind-exposed structures.

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

Do not support loads directly from truss connection points.

Inspect the plate, receivers, tapered pins, R-clips, and connected truss before every use.

Account for dynamic, transverse, and environmental forces, including wind loads.

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