EVT12S-4IN Black | 4-Inch Aluminum Truss Spacer (12×12 Box Truss Plated) – Matte Black

The EVT12S-4IN Black Aluminum Truss Spacer is a precision-manufactured 4-inch structural spacer finished in a durable matte black powder coat, purpose-built for 12-inch square end-plated aluminum truss systems where the structure needs to disappear. In audience-facing rigs, broadcast studios, and black-box theaters, visible silver truss is not an option. This spacer provides the same controlled spacing between truss sections as the standard EVT12S-4IN while delivering a non-reflective, low-visibility profile that blends into dark stage environments without catching stage lighting or camera glare.

Function & Compatibility:

Unlike conical systems, the EVT12S series utilizes an industry-standard nut-and-bolt end-plate connection. This spacer features a rigid square profile that matches the geometry of standard 12″ box truss, ensuring a seamless structural transition. The matte black powder coat is applied over 6061-T6 aluminum alloy, so the structural performance is identical to the standard version — the difference is purely visual. It is the go-to solution for dialing in truss lengths on touring rigs, broadcast grids, theatrical lighting systems, and corporate stage builds where a consistent black-out aesthetic is non-negotiable.

Key Features

• Precise Extension: Adds exactly 4 inches to the truss run — the final dimensional adjustment for video wall support frames where the truss must match exact pixel-pitch panel layouts, and for stage builds that need to land on specific venue dimensions.
• Professional Black Finish: High-quality matte black powder coat eliminates glare, prevents silver reflections from bleeding through LED panel gaps, and ensures the truss visually disappears against dark backdrops, curtains, and stage blacks.
• Included Hardware: Ships complete with 4x Grade 8 Bolts, Nuts, and Washers (black finish hardware may vary; standard zinc/galv typically supplied unless specified) for immediate assembly.
• Heavy-Duty Construction: Fabricated from 6061-T6 Aluminum Alloy underneath the powder coat — full structural integrity with zero weight penalty over the standard version.
• End-Plated Design: Compatible with EVT12S and other standard 12-inch plated truss systems using bolt connections.
• TÜV Specifications: Fabricated in accordance with strict TÜV manufacturing standards — the powder coat finish does not alter the engineering certification.

Who It’s For

• Staging & Event Production Riggers — You’re building an audience-facing rig and the production designer has spec’d black truss. Your venue is 23’4″ and your inventory is all 5ft and 8ft sticks. You need 4 inches to close the span, and it has to be black. This is that piece.
• Lighting Grid Designers & Integrators — You’re hanging a grid in a black-box theater, concert hall, or broadcast studio where anything overhead has to vanish. The total run has to hit your pick points exactly, and silver aluminum above the performance area is not acceptable. The EVT12S-4IN Black gives you the precision adjustment without breaking the sightline.
• LED & Video Wall Framers — Your support frame sits directly behind the LED panels. Silver truss behind the array reflects light through panel gaps and bleeds into the image. Black truss eliminates that problem — and this spacer lets you match the frame to the exact panel layout without compromise.
• Broadcast & Film Production Crews — Your overhead grid is visible on camera or in the background of a live broadcast. Silver truss creates reflections and visual noise that the DP will flag immediately. Matte black is standard spec for broadcast-grade studio grids, and this spacer keeps that spec consistent down to the last 4 inches.
• Trade Show & Exhibit Builders — The booth design calls for a premium branded look and the client’s creative team won’t sign off on exposed silver aluminum. You need to hit a 10×20 footprint and the black spacer bridges the gap between your standard lengths and the exact floor plan dimension.
• Rental & Staging Companies — You stock both silver and black truss because half your clients — corporate events, theatrical tours, broadcast gigs — require stealth rigs. The 4-inch black spacer is a fleet essential for any rental house servicing those markets.
• Rigging & Structural Engineers — The finish is cosmetic; the engineering is not. TÜV-standard fabrication and Grade 8 hardware mean this component spec’s into a professional structural drawing the same as the standard aluminum version. The powder coat changes nothing about the load path.

Designed by Evolve Truss, the EVT12S-4IN Black delivers the same structural reliability as the standard version with the stealth finish that professional theatrical and broadcast environments demand.

⚠️ Safety & Engineering Notice

❗ Structural Warning: Adding a spacer to a truss run does NOT increase the overall load capacity of the span. The allowable load is determined by the total span length and the weakest component. Do not support loads directly from the spacer connection points.

Important Guidelines for Safe Use:

• Inspect the end plates and bolt holes for deformation or wear before every use.
• Ensure all Grade 8 bolts are properly torqued to manufacturer specifications.
• Handle with care to prevent chipping the powder coat finish — exposed aluminum beneath the coating may compromise the visual consistency of the rig.
• Do not mix truss components from different manufacturers unless the bolt pattern and plate dimensions have been strictly verified.
• The purchase of this product does not authorize specific installations; a licensed professional engineer shall review all structures, lighting plots, or other aluminum truss uses.

⚠️ Compatibility Warning for Mixed-Brand Builds

Crucial Steps for Safe Assembly:

• Verify Bolt Patterns: Plated truss varies by manufacturer. Compare your existing truss plate dimensions against EVT12S specifications before purchase.
• Check Alignment: Ensure chord alignment is precise to prevent uneven loading on the bolts.
• Mixing incompatible plated truss can lead to structural failure.
