Description

EVT12S-4FT | 4-Foot Aluminum Truss Section (12×12 Box Truss Plated)

The EVT12S-4FT Aluminum Truss Section is a 4-foot straight segment for 12-inch square end-plated aluminum truss systems — the primary building block that production companies, fabrication teams, and facility installers order in quantity because four feet hits the sweet spot between single-person handling and meaningful span coverage per piece. At 48 inches and 30 pounds, this is the section that gets stocked deep in rental fleet warehouses and deployed in multiples across every build: three sections reach 12 feet, five sections make 20 feet, and pairing with a 1-foot spacer hits a clean 5-foot half-span. Touring production companies cycling the same rig through dozens of venues per run, military fabrication teams packing portable mast assemblies into standard vehicle beds, gymnasium installers anchoring scoreboard grids to roof-deck steel, and greenhouse operators spanning irrigation booms between growing-house columns all buy the 4-foot in bulk — it’s the length that scales from a single tower to a full arena grid without ever feeling too short to be useful or too long to handle alone.

Function & Compatibility:

The EVT12S-4FT connects through bolted end-plates — no conical coupler hardware. It shares the same 12-inch square profile, four-chord structure, and through-bolt plate pattern as every other EVT12S component in the catalog. 6061-T6 aluminum alloy throughout — the same structural grade carried by the 5-foot and 10-foot sections it typically anchors between, with full diagonal bracing spanning all 48 inches for standalone lateral rigidity in any orientation. The 4-foot length sits in the middle of the straight-section lineup: long enough to cover real distance with fewer connections per span than shorter sections, compact enough to fit standard cargo beds, stack flat on transport carts, and clear doorways without tilting. It bolts into horizontal overhead grids, vertical tower legs, angled braces, and ground-level base frames with equal structural authority — the section you build around when the project needs to scale.

Key Features

• Core Inventory Length: A complete 4-foot (48-inch) truss segment with full diagonal bracing — the section most often ordered in multiples because it divides efficiently into 12-foot, 16-foot, and 20-foot spans while remaining a true one-person carry at 30 lbs.
• Consistent Aluminum Surface: Standard brushed aluminum finish identical across all silver EVT12S components — no visual mismatch when mixing section lengths within the same build.
• Complete Bolt Package: Every section ships with 4x Grade 8 Bolts, Nuts, and Washers — hardware is in the box, not on a separate line item, so bulk orders arrive assembly-ready.
• Production-Grade Alloy: Built from 6061-T6 aluminum — the standard structural alloy across the full EVT12S family, ensuring uninterrupted load path continuity from section to section through every bolted connection.
• Cross-Compatible End Plates: EVT12S through-bolt plate geometry compatible with other standard 12-inch plated truss systems — Tomcat, James Thomas Engineering, Milos, Show Solutions, and others sharing the same bolt pattern and plate dimensions.
• TÜV Specifications: Manufactured to TÜV-certified standards — every 4-foot section carries the same engineering certification as every other length in the EVT12S series, regardless of quantity ordered.

Who It’s For

• Touring Production Companies — You’re stocking a road-ready truss inventory that builds and strikes the same rig across dozens of venues per tour cycle. The 4-foot section is the core length on the truck because it divides efficiently into the stage widths you encounter most — three sections make 12 feet, five make 20, and adding a spacer or shorter section fine-tunes the total to fit rooms that don’t land on round numbers. At 30 pounds, one stagehand can carry it from truck to stage during fast load-ins, and the consistent bolt pattern means every section from every case connects without sorting or matching.
• Military & Defense Fabrication Teams — You’re assembling portable communication antenna masts, equipment shelter frameworks, and field-deployable sensor platforms from modular components that ship in standard vehicle beds and go together without cranes. A 4-foot section fits within the cargo dimensions of Humvees, utility trailers, and ISO containers, and multiple sections stack flat and strap down for rapid deployment. Small crews assemble and tear down in forward operating environments where every minute of setup time and every inch of transport space is accounted for.
• Gymnasium & Recreation Center Installers — You’re mounting permanent overhead truss grids for basketball scoreboards, volleyball net tensioning hardware, and retractable divider curtain tracks in school gyms and community rec centers. The 4-foot length matches the standard spacing between roof joists and steel purlins in typical gymnasium construction, letting you anchor each end of the section directly to existing structural steel without fabricating custom brackets or adding intermediate supports that complicate the ceiling plane.
• Greenhouse & Controlled-Environment Agriculture Operators — You’re suspending irrigation booms, grow-light rails, and climate-monitoring sensor arrays from overhead truss grids that span between greenhouse columns. A 4-foot section covers the typical column-to-column bay width in commercial growing facilities, and the 6061-T6 aluminum construction holds up in the high-humidity, high-temperature environments that corrode steel framing within seasons — keeping your overhead infrastructure intact through years of continuous growing cycles.
• Rigging & Structural Engineers — The EVT12S-4FT is a fully braced structural section carrying the same 6061-T6 alloy specification and TÜV-certified fabrication as every other EVT12S component. It functions as a cataloged section in any orientation on an engineered drawing. Refer to the official EVT12S load tables for allowable loads at the total span length and support configuration in your design.

Designed by Evolve Truss, the EVT12S-4FT is the section you order in quantity and deploy in every position — the 4-foot piece that scales from a single tower to a full production grid while staying a one-person lift from truck to truss line.

⚠️ Safety & Engineering Notice

❗ Critical Load Rating Information: The rated load capacity for this 4-foot segment is governed by the overall system design — span length, support spacing, and load distribution all factor into the allowable capacity. For precise specifications, always refer to the official EVT12S Truss Series Load Tables for the span configuration you are building. Consult a qualified engineer before use.

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.
