EVT12S-3/8IN Black | 0.375-Inch Aluminum Truss Spacer Plate — 12-Inch Square End-Plate Bolt Truss — Matte Black Powder Coat

The EVT12S-3/8IN Black Aluminum Truss Spacer is a 3/8-inch (9.52 mm) precision plate in a matte black powder coat finish for 12-inch square end-plate bolt truss systems — the smallest cataloged adjustment in the EVT12S spacer lineup, built for dark-finish builds where a bare aluminum plate at the joint would create a visible silver line between black truss sections. Machined from solid 6061-T6 aluminum alloy with a 12-inch × 12-inch square profile matching standard EVT12S end-plate geometry, this 5.27-pound spacer plate bolts between sections using the same nut-and-bolt end-plate connection as every other joint in the system — shipped with 4× Grade 8 bolts, nuts, and washers for immediate assembly. The factory-applied matte black powder coat absorbs light instead of reflecting it, keeping the spacer invisible at the connection point in studio grids that live in the background of produced images, concert venue overheads running under UV and colored washes, themed attraction structures that guests look up into, and worship facility ceilings where the congregation sees every component at every service.

Function & Compatibility:

The EVT12S-3/8IN Black is a flat spacer plate that sandwiches between two end-plated truss sections or between a section and another spacer using the standard bolted end-plate connection. The bolt-hole pattern matches EVT12S 12-inch square truss end-plate geometry, and the included Grade 8 fasteners maintain the same connection strength as every other bolted joint in the run. At 3/8 inch thick, this is the fractional fine-tuning piece — the smallest available increment for closing a dimensional gap in a 12-inch bolt truss layout — and it stacks with other EVT12S spacers when a larger total adjustment is needed. Built from EN AW-6061-T6 aluminum alloy under TÜV manufacturing standards and finished in a matte black powder coat that resists scratching and absorbs light under stage, studio, and UV conditions. The finish eliminates the reflective contrast that an uncoated spacer creates between dark truss sections, maintaining visual uniformity across the entire grid — including at the smallest joint in the build.

Key Features

• Matte Black Powder Coat Finish: Factory-applied matte black powder coat across the full plate surface absorbs light and eliminates the reflective silver line that an uncoated spacer creates between dark truss sections — invisible under studio lighting, UV, colored washes, and stage spots.
• Smallest Precision Increment: A 3/8-inch (9.52 mm) spacer plate — the finest dimensional adjustment in the EVT12S spacer lineup, closing fractional gaps that no standard truss section or larger spacer can address on its own.
• Grade 8 Hardware Included: Ships with 4× Grade 8 bolts, nuts, and washers for immediate high-strength assembly — no separate fastener order, no delay between unboxing and bolt-up.
• 12-Inch Square End-Plate Profile: Bolt-hole pattern and plate geometry match EVT12S and other standard 12-inch plated bolt truss systems, preserving full structural continuity through the spacer joint.
• Stackable with Other Spacers: Combines with other EVT12S spacer thicknesses to reach custom total adjustments — layer the 3/8-inch with larger spacers to build the exact dimension the layout demands.
• 6061-T6 Solid Aluminum Construction: Machined from EN AW-6061-T6 aluminum alloy — the same structural-grade material carried by every EVT12S truss section in the system.
• TÜV Manufacturing Standards: Produced under TÜV-certified processes — the spacer meets the same engineering-grade certification that structural and rigging engineers require on professional drawings.

Who It’s For

• Broadcast & Film Studio Grid Technicians — Your studio overhead grid lives in the background of every shot — news desks, interview sets, talk shows, sound stages — and the DP expects a uniform dark ceiling line overhead. When a truss run needs a 3/8-inch adjustment to align with a pick point or reach a specific trim height, a silver spacer plate between black sections reflects studio lighting and pulls focus to the rigging in wide and overhead frames. The matte black finish absorbs that light and keeps the spacer invisible at the joint, so the grid reads as one continuous dark structure from every camera position in the studio.
• Concert Venue & Nightclub Permanent Install Crews — Your fixed overhead truss runs under UV blacklight, saturated color washes, and high-intensity moving heads in a room where bare aluminum fluoresces, glows, and announces itself to every person in the audience. A silver spacer plate between black truss sections catches those lighting states and draws attention to the structure instead of the performance. The matte black finish stays dark under every condition the venue throws at it — UV, strobes, full color, full blackout — keeping the spacer invisible in the grid so the lighting design stays the focus.
• Themed Attraction & Immersive Experience Fabricators — You’re building truss structures inside theme park rides, escape rooms, haunted attractions, and immersive art installations where guests walk through the space and look directly up at the overhead grid. A single silver plate in an otherwise black structure breaks the illusion at exactly the point where two truss sections meet — the one spot the set designer needs to be seamless. The matte black spacer maintains the visual continuity the creative team specified, preserving the designed environment even at the smallest structural joint in the build.
• House of Worship & Performance Venue Technical Directors — Your facility has a permanent black truss grid visible to the congregation or audience at every service, every show, every rehearsal. The building committee approved a clean dark overhead, and every component in that grid — including spacers — needs to match. When a grid expansion, realignment, or trim-height adjustment requires a 3/8-inch spacer, the black version closes the gap without introducing a contrasting silver element at the connection point that wasn’t in the approved design.
• Structural & Rigging Engineers — The EVT12S-3/8IN Black is a 3/8-inch (9.52 mm) solid 6061-T6 aluminum spacer plate with a matte black powder coat finish and a 12-inch square bolt-hole pattern matching EVT12S end-plate geometry, fabricated under TÜV manufacturing standards with Grade 8 connection hardware included. The powder coat does not alter the plate’s structural properties. Adding a spacer to a truss run does NOT increase overall load capacity — allowable loads are determined by the total span length and the weakest component. Do not support loads directly from the spacer connection points. Refer to the official EVT12S Load Tables for the complete assembled span. A licensed professional engineer must review all structures.

Designed by Evolve Truss, the EVT12S-3/8IN Black is the fractional spacer for dark-finish grids — 3/8 inch of precision that closes the gap and disappears into the joint without leaving a silver line behind.

⚠️ 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 during transport and assembly to prevent chipping or scratching the powder coat finish. Surface damage does not affect structural integrity but may impact appearance.
• Do not mix truss components from different manufacturers unless the bolt pattern and plate dimensions have been strictly verified for compatibility.
• 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.
