EVT12S-1/2IN Black | 0.5-Inch Aluminum Truss Spacer Plate — 12-Inch Square End-Plate Bolt Truss — Matte Black Powder Coat

The EVT12S-1/2IN Black Aluminum Truss Spacer is a half-inch (12.7 mm) precision plate in a matte black powder coat finish for 12-inch square end-plate bolt truss systems — the fractional adjustment that disappears into a dark truss grid instead of announcing itself as a silver line between two black sections. Machined from solid 6061-T6 aluminum alloy with a 12-inch × 12-inch square profile matching standard EVT12S end-plate geometry, this 7.02-pound spacer plate connects through the same nut-and-bolt end-plate system used at every other joint in the assembly — shipped with 4× Grade 8 bolts, nuts, and washers for immediate installation. The factory-applied matte black powder coat absorbs light across the full plate surface, keeping the spacer invisible in environments where even the smallest exposed component has to hold a dark visual standard: planetarium domes where projected star fields wash out against reflective metal, escape rooms where guests look directly up into the grid, flagship retail spaces where the truss structure is an architectural element on display, and data center overhead runs where matte black hardware is the facility-wide specification.

Function & Compatibility:

The EVT12S-1/2IN Black is a flat spacer plate that bolts between two end-plated truss sections or between a section and another spacer in the standard EVT12S connection sequence. The bolt-hole pattern aligns with EVT12S 12-inch square truss end plates, and the included Grade 8 hardware provides the same fastener strength as every other bolted joint in the run. At half an inch thick, the spacer sits in the mid-range of the EVT12S fractional spacer lineup — resolving gaps that fall between the thinnest available plate and the larger standard increments — and stacks with other EVT12S spacers for compound adjustments when the total correction exceeds a single plate. Fabricated from EN AW-6061-T6 aluminum alloy under TÜV manufacturing standards and coated in a matte black powder coat that resists scratching under normal handling and eliminates the reflective contrast that an uncoated plate creates between dark truss sections. The finish holds under stage lighting, overhead task lighting, UV, and ambient conditions without fading or losing its non-reflective properties.

Key Features

• Matte Black Powder Coat Finish: Factory-applied matte black powder coat across the full plate face absorbs light and eliminates the visible silver line that an uncoated spacer creates between dark truss sections — maintaining a uniform dark appearance at every connection point in the grid.
• Half-Inch Precision Increment: A 0.5-inch (12.7 mm) spacer plate that resolves a measured half-inch gap in a 12-inch bolt truss run with a certified, cataloged component — no field fabrication, no uncertified shims, no visual compromise.
• Grade 8 Hardware Included: Ships with 4× Grade 8 bolts, nuts, and washers matched to EVT12S connection standards — ready for immediate high-strength bolt-up out of the box.
• 12-Inch Square End-Plate Geometry: Bolt-hole pattern and plate dimensions match EVT12S and other standard 12-inch plated bolt truss, maintaining structural continuity through the spacer joint without any modification to the adjacent sections.
• Stackable Across the Spacer Range: Combines with other EVT12S spacer thicknesses — including the 3/8-inch, 4-inch, and larger plates — to assemble compound adjustments that reach any target dimension the layout demands.
• 6061-T6 Solid Aluminum: Machined from EN AW-6061-T6 aluminum alloy — the same structural-grade material as every EVT12S truss section, with no material step-down at the spacer.
• TÜV Manufacturing Standards: Produced under TÜV-certified processes — carries the same production certification as every other component in the EVT12S catalog.

Who It’s For

• Planetarium & Observatory Dome Riggers — Your projection dome or observatory interior demands absolute darkness on every overhead surface so projected star fields, celestial animations, and astronomical imagery render against a true-black canopy without washing out against reflective hardware. A half-inch silver spacer plate between black truss sections catches even the lowest ambient light levels in the dome and creates a visible seam in a grid that’s supposed to be invisible. The matte black finish eliminates that reflection entirely, keeping the spacer dark against the dome surface so the projected sky reads as uninterrupted space — not a ceiling with hardware showing through it.
• Escape Room & Immersive Attraction Builders — You’re hiding structural truss behind themed scenic elements, but overhead grids in escape rooms, walk-through haunts, and immersive installations are often partially or fully visible to guests who look up — and they always look up. A silver plate in an otherwise black grid reveals the infrastructure behind the illusion at exactly the joint where two sections meet. The matte black spacer holds the uniform dark ceiling the set designer specified, keeping the half-inch structural adjustment invisible even in rooms running uplighting, blacklight effects, or directional spots that sweep across the overhead.
• High-End Retail & Flagship Store Fixture Installers — Luxury retail environments and flagship store interiors use exposed black truss grids as deliberate architectural elements — hanging merchandise displays, directing track lighting, and supporting branded signage in spaces where every structural detail is part of the customer experience. Every connection point is visible at eye level and from below, and the expectation is that the grid looks designed, not assembled from parts. A matte black spacer at a half-inch adjustment integrates into the grid as though it were part of the original architectural specification — not a corrective plate bolted in after the fact to fix a measurement the installer missed.
• Data Center & Server Room Overhead Infrastructure Contractors — Your data center runs overhead truss for structured cable management, cooling duct support, and environmental sensor mounting above the hot and cold aisles — and the facility standard specifies matte black hardware across all overhead infrastructure to reduce visual clutter under maintenance task lighting. A silver spacer in an otherwise uniform black overhead grid stands out during every maintenance walk and every client tour of the facility. The matte black plate keeps the truss grid aesthetically consistent with the rest of the overhead infrastructure while closing a half-inch alignment gap at a column transition, row boundary, or cabinet run terminus.
• Structural & Rigging Engineers — The EVT12S-1/2IN Black is a 0.5-inch (12.7 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, weighing 7.02 lbs, 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-1/2IN Black is the half-inch plate for builds where the gap is measured and the finish is non-negotiable — one spacer that closes the dimension and holds the dark line from one end of the grid to the other.

⚠️ 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, cracking, or wear before every use.
• Ensure all Grade 8 bolts are 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: End-plate bolt configurations vary by manufacturer. Compare your existing truss plate dimensions against EVT12S specifications before purchase.
• Confirm Chord Alignment: Ensure chord positions align precisely across the spacer joint to prevent uneven bolt loading.
• Mixing incompatible plated truss can compromise connection integrity and lead to structural failure.
