EVT12S-BP40AR1B

Product Description

The EVT12S-BP40AR1B is the matte black version of the EVT12S-BP40AR1 — a precision-machined aluminum base plate with an oversized 20 x 40-inch (508 mm x 1,016 mm) footprint engineered for EVT12S 12-Inch End-Plate Bolt Truss Series and other standard 12-inch bolt truss systems, finished in a matte black powder coat that eliminates the silver base at the foot of a dark column. The wide rectangular footprint distributes vertical loads across a larger floor contact area than compact base plates, delivering greater tipping resistance for tall totems, signage towers, lighting columns, and trade show display structures in environments where every structural element — including floor hardware — needs to hold a dark visual standard. A laser-cut carry handle is integrated directly into the slab for fast, safe repositioning during setup and strike. Fabricated from 6061-T6 aluminum alloy with a matte black powder coat finish. Full assembly height is 37 mm (1.46 in) — comprising the 12 mm top slab and the full perimeter frame. Weighs 45 lb (20.41 kg). Hardware is not included — sold separately. STEP and DWG CAD files available upon request.

Key Features

• Matte black powder coat finish: Anti-reflective finish absorbs light rather than reflecting it — the base plate disappears under studio lighting, colored washes, UV light, and controlled dark room conditions where bare aluminum would create a visible hot spot or glow at the base of the column.
• 20 x 40-inch footprint: The wide rectangular base delivers a larger floor contact area and more leverage against tipping than compact square plates — the right choice for tall totems, multi-section towers, and structures where a narrow base would require supplemental ballast to hold.
• 37 mm (1.46 in) full assembly height: The complete plate assembly — top slab plus perimeter frame — sits 37 mm off the floor. The top slab alone is 12 mm (0.47 in) thick. Both dimensions matter for clearance planning in tight floor setups.
• Laser-cut carry handle: Integrated directly into the slab — no separate handle hardware to lose, no sharp edges. Pick up and reposition the plate with one hand during setup.
• 6 pre-drilled bolt holes: Positioned for direct connection to EVT12S end-plate bolt truss uprights. Compatible with other standard 12-inch end-plate bolt truss systems — exact fit with other brands is not guaranteed.
• 6061-T6 aluminum alloy: High-strength, corrosion-resistant structural aluminum — same material class as the EVT12S truss system it supports, with a matte black powder coat over the brushed substrate.
• Powder coat care: Handle with care to prevent chipping the matte black finish, which can expose raw aluminum underneath. Inspect the finish before each use and touch up any chips that compromise the dark visual.
• Hardware not included: Connecting bolts and hardware are sold separately. Confirm bolt specification with your truss system before ordering hardware.
• STEP and DWG CAD files available upon request: For integration into structural drawings, venue floor plans, and 3D models.
• 1-year limited warranty against manufacturing defects.

Who It's For

• Broadcast and film studio technical directors: Your studio floor and overhead infrastructure are designed to disappear from camera. A silver base plate at the foot of a black truss column reflects key lights, ring lights, and studio wash — creating a hot spot at floor level that pulls focus in wide shots and low-angle frames. The matte black finish absorbs that light instead, keeping the base plate invisible under studio lighting conditions where bare aluminum would never pass a camera check.
• Nightclub and permanent venue installation crews: Your nightclub and live music venue floor runs under UV light, colored washes, and moving heads that make bare aluminum hardware glow. A matte black base plate under a black truss totem maintains the dark visual continuity of the rig from floor to fixture, and the 20 x 40-inch footprint provides the tipping resistance needed for tall column builds without requiring additional floor anchors in a venue that sees heavy foot traffic every night.
• Luxury event and branded experience designers: Your premium event environments — product launches, VIP activations, and experiential marketing installations — specify black hardware throughout to maintain a cohesive dark aesthetic. A brushed aluminum base plate at the foot of a black totem reads as an oversight to a design-literate client. The black version eliminates that detail entirely and keeps the structural base invisible against dark stage floors and black carpet.
• Haunted attractions and dark experience operators: Your haunted house, dark ride, or immersive scare attraction builds permanent column structures that need to blend into controlled dark environments. A silver base plate on a black column catches even faint ambient light in a blackout scene. The matte black base plate disappears under those conditions — maintaining the visual environment your production team designed and eliminating a detail that breaks immersion at floor level.

Why a Wider Footprint Matters

• Tipping resistance: A 20 x 40-inch base provides substantially more resistance to lateral tipping forces than a compact plate — critical for tall single-column totems and lighting towers where the center of mass is high above the base.
• Load distribution: The larger contact area spreads vertical and eccentric loads across more floor surface, reducing point stress on finished floors, stage decking, and convention hall carpet.
• Ballast and anchoring clearance: The extended footprint provides perimeter space for sandbag placement or supplemental anchoring when additional stability is required by venue safety requirements or engineering review.

Safety and Engineering

• Does not increase load capacity: This base plate provides a wider floor contact area and improved tipping resistance. It does not increase the vertical load rating of the truss system it supports.
• Hardware torque: All connecting bolts must be torqued to the truss manufacturer's specified value. Verify bolt specification and torque requirements before assembly.
• Pre-use inspection: Inspect the plate, frame, bolt holes, and powder coat finish before every use. Remove from service immediately if any deformation, cracking, or thread damage is found.
• Ballast: Tall totem and tower structures may require supplemental ballast or floor anchoring regardless of base plate size. Engineering review determines ballast requirements — the base plate alone does not substitute for a stability analysis.
• Assembly personnel: Assembly and rigging should be performed by personnel qualified to work with bolt truss systems.
• Engineering review: A licensed professional engineer must review all load-bearing designs, tall totem structures, and permanent installations prior to use.
