What is the difference between this base plate and a standard 20 × 20-inch base plate?

The EVT12S-BP40AR1 is 20 × 40 inches — twice the length of a standard 20 × 20-inch base plate. The longer dimension significantly increases tipping resistance in the direction of the plate's length. This matters most on tall totems and signage towers where the center of gravity is high and lateral forces from top-heavy fixtures or banner loads create a tipping moment that a square plate cannot resist as effectively. Position the long dimension facing the direction of greatest lateral load for maximum benefit.

Does this base plate come with the hardware needed to bolt EVT12S truss to it?

No. The EVT12S-BP40AR1 does not include connecting hardware. The six pre-drilled bolt holes are sized for standard EVT12S end-plate bolt hardware, which must be purchased separately. Ensure you have the correct Grade 8 bolts, nuts, and washers for your specific connection before assembly.

Can I stack sandbags or water barrels on this base plate to add ballast weight?

Yes. The 20 × 40-inch flat plate surface provides sufficient space to place sandbags, water barrels, or other ballast along the length of the plate on both sides of the truss column connection point. Distributing ballast symmetrically along the 40-inch length provides the most even resistance against tipping in both directions. Never stack ballast above the truss connection point, and always have a licensed structural engineer calculate the required ballast for your specific column height and top load before building the structure.

Product Overview

A Wide Aluminum Ground Plate for 12 Inch End-Plate Bolt Truss.

The EVT12S-BP40AR1 is a 20 x 40 in brushed-aluminum base plate for compatible EVT12S and standard 12 inch end-plate bolt-truss systems. Its rectangular footprint provides a larger floor-contact area in one direction than a 20 x 20 in square plate. The final orientation, upright height, load path, ballast, anchoring, floor condition, and stability measures must be determined for the complete installed structure.

20 x 40 Inch Footprint

A 508 x 1,016 mm rectangular plate footprint for planned truss-column and exhibit-support layouts.

6061-T6 Aluminum

Constructed from 6061-T6 aluminum alloy with a brushed aluminum finish.

Integrated Carry Handle

A laser-cut carry handle is integrated into the plate for planned handling and placement.

Six Pre-Drilled Holes

Provides six pre-drilled holes for the documented truss connection interface.

Wide Footprint Design

More Ground-Contact Area Along One Planned Direction.

The 40 inch dimension extends the base plate footprint beyond a compact square plate. Position and orient the plate according to the approved layout and anticipated loading directions. A wide footprint is a product feature, not a universal stability, ballast, wind, or tower-height rating.

Rectangular Geometry

The 20 x 40 in layout provides a longer planned footprint direction for floor-layout and support-design considerations.

Ballast Clearance

The extended plate surface can accommodate planned supplementary ballast placement when required by the complete project design.

Floor-Layout Planning

Use the documented footprint and 37 mm assembly depth when planning clearances, aisles, display components, and floor conditions.

No Automatic Rating

The base plate does not independently establish allowable loading, required ballast, or resistance to wind and lateral forces.

Applications

For Planned Truss Columns, Totems, Displays, and Ground-Support Layouts.

Use the EVT12S-BP40AR1 where an approved layout calls for a wide aluminum base plate under a compatible 12 inch end-plate bolt-truss upright. Applications may include planned display columns, exhibit structures, scenic supports, lighting positions, and temporary technical installations. Confirm the completed structure and installation requirements before use.

Truss Columns

For compatible EVT12S or standard 12 inch bolt-truss uprights in an approved ground-support layout.

Exhibit Structures

Installation Checks

Start with the Ground Surface. Then Verify the Connection and Complete Stability Plan.

A base plate is one element of a vertical structure. Installation requires a level and appropriate bearing surface, a verified mounting interface, correct hardware, plumb upright alignment, controlled loads, and any additional ballast or anchoring required by the complete design. These checks do not replace project-specific engineering review.

01 — Verify the Surface

Confirm the floor or support surface is level, stable, and appropriate for the complete base plate and structure load.

02 — Inspect the Base Plate

Inspect the plate, frame, holes, handle opening, finish, and selected hardware for damage, deformation, cracks, or defects.

03 — Confirm Hardware

Select and verify the correct bolt, nut, washer, grade, engagement, and torque requirement for the specific truss system.

04 — Align and Secure the Truss

Confirm end-plate alignment, install the specified hardware, and secure the connection according to the approved system requirements.

05 — Check Plumb and Load Distribution

Set the vertical member plumb and confirm applied loads are distributed as required by the approved design.

06 — Add Required Stability Measures

Install specified ballast, anchors, guying, bracing, barriers, or other measures required by the complete structural and site plan.

Stability and Safety

A Wide Footprint Is a Product Feature. It Is Not a Universal Stability Calculation.

The 20 x 40 in footprint provides a documented floor-contact geometry, but the base plate alone does not establish safe tower height, vertical or lateral capacity, ballast requirements, wind suitability, anchoring requirements, or the stability of a finished structure. Those outcomes depend on the height and weight of the upright structure, center of gravity, applied and eccentric loads, floor condition, footprint orientation, public access, impact risk, ballast, bracing, anchoring, and local requirements.

A qualified professional must determine whether the base plate, ballast, anchoring, bracing, and support arrangement are adequate for the specific structure and site.

Additional ballast or other stabilization may be required for tall vertical builds, lateral loads, outdoor exposure, wind, uneven surfaces, public areas, or other site conditions.

Keep the vertical truss plumb and maintain the load distribution required by the approved design.

Do not use a damaged, bent, cracked, corroded, or otherwise compromised plate, frame, truss connection, bolt hole, or fastener.

Use barriers, covers, markings, or other risk controls where the base plate presents a trip, impact, or public-access hazard.
