Product Description

EVT12S-7IN | 7-Inch Aluminum Truss Spacer (12×12 Box Truss Plated)

The EVT12S-7IN Aluminum Truss Spacer is a 7-inch structural component engineered for 12-inch square end-plated aluminum truss systems — and it exists because real-world dimensions don’t land on even numbers. As an odd-inch spacer, this is the component that solves dimensional problems even-inch increments cannot: closing the final gap in a custom span to match an architect’s fractional dimension, hitting a booth-edge position that falls between 6 and 8 inches, adapting an existing grid to a building’s fixed geometry, or stacking with other spacers to reach a measurement no single standard section covers. Production engineers drafting rigging plots to exact venue blueprints, trade show builders working to rigid floor-plan assignments, riggers retrofitting venues with fixed structural clearances, and rental fleet coordinators stocking graduated spacer shelves all reach for the 7-inch because it eliminates the workaround.

Function & Compatibility:

The EVT12S-7IN is a bolted end-plate truss component — not a conical coupler system. It carries the same square cross-section and through-bolt pattern as every other EVT12S piece, dropping into any run as a native section rather than a field-modified adapter. 6061-T6 aluminum alloy throughout — the same structural grade used in the full-length sections. At 7 inches, it fills the odd-dimension gap that 4-inch, 5-inch, and 6-inch spacers leave behind, and it pairs with any of them to build compound fractional extensions: 7 + 5 = 12 inches, 7 + 4 = 11 inches, 7 + 6 = 13 inches. One certified, bolt-ready component — no shimming, no cutting, no guesswork.

Key Features

• Odd-Inch Precision: Adds exactly 7 inches to the truss run — the increment that standard even-length spacers cannot provide, letting engineers close out a span to the architect’s spec without rounding up to the next full section or stacking multiple smaller spacers that add unnecessary connection points and weight.
• Professional Finish: Standard brushed aluminum surface that integrates visually with silver trussing — clean, consistent, production-ready.
• Included Hardware: Ships with 4x Grade 8 Bolts, Nuts, and Washers — unbox and bolt directly into the run with no additional hardware purchase.
• Structural-Grade Alloy: Built from 6061-T6 aluminum — the same material specification as full-length EVT12S truss sections, maintaining load continuity across the connection.
• End-Plated Connection: Standard EVT12S through-bolt end-plate geometry, cross-compatible with other 12-inch plated truss systems sharing the same bolt pattern and plate dimensions.
• TÜV Specifications: Built to TÜV-certified manufacturing and quality standards — the odd-inch length does not alter the engineering certification or allowable load path.

Who It’s For

• Production Engineers & Structural Designers — You’re drafting rigging plots to exact dimensions dictated by venue blueprints, load calculations, and scenic ground plans. The 7-inch spacer is the odd-increment precision tool that lets you close out a span to the architect’s spec without rounding up to the next full section length or stacking multiple smaller spacers that add unnecessary connection points and weight to the engineered structure.
• Trade Show & Exhibition Builders — You’re building to rigid floor-plan dimensions assigned by show management, and the overhead header or booth-edge position falls between a standard 6-inch and 8-inch increment. The 7-inch spacer hits that exact position so signage, banners, and overhead displays align with the booth layout — no awkward gaps or overhangs that make a display look unfinished.
• Riggers Working Retrofit & Renovation Projects — You’re adapting a truss grid to a venue with fixed structural dimensions — ceiling heights, column spacing, catwalk clearances — that rarely land on even numbers. The 7-inch spacer lets you match the truss to the building’s actual geometry rather than forcing the building to accommodate the truss, reducing field modifications and speeding up load-in.
• Warehouse & Inventory Coordinators for Rental Fleets — You need a complete spacer inventory that means fewer substitutions and faster pull-sheet fulfillment. The 7-inch fills the gap between the 6-inch and 8-inch on the shelf, and it pairs with the 4-inch and 5-inch to create compound dimensions (11 inches, 12 inches) — ensuring the warehouse can satisfy any odd-dimension request without sending a crew to the job site with the wrong parts.
• Rigging & Structural Engineers — The 7-inch spacer carries the same 6061-T6 alloy specification and TÜV-certified fabrication as every other EVT12S component. It specs into an engineered drawing with full structural authority — the odd-inch length does not introduce a reduced-capacity junction or require a derating note on the stamped plan.

Designed by Evolve Truss, the EVT12S-7IN is the odd-inch precision spacer that turns non-standard dimensions into solved problems — one bolt-on component, exact fit, zero workaround.

⚠️ 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.
• 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.
