EVT12S-1FT

Product Description

EVT12S-1FT — 1-Foot Aluminum Truss Spacer — 12-Inch Square End-Plate Bolt Truss

The EVT12S-1FT Aluminum Truss Spacer is a one-foot (304.8 mm) spacer for 12-inch square end-plate bolt truss systems — the longest single spacer in the EVT12S lineup, handling a full 12-inch gap in one component instead of stacking shorter plates. Four 50 mm (1.96 in) OD / 3 mm wall main chord tubes run between two end plates, connected by welded flat gusset panels that hold the 12-inch square box profile across the one-foot span. At 11.46 pounds, this spacer bolts between sections using the standard end-plate connection and adds exactly one foot to the run. Fabricated from 6061-T6 aluminum alloy, this is the spacer that solar racking engineers insert when a rooftop framework needs a one-foot extension to reach the next anchor, that conveyor support builders drop at column transitions to maintain alignment across the gap, that aquarium exhibit fabricators use to fill short spans between scenic panels, and that military shelter teams carry for adjusting deployable frame dimensions to mission-specific equipment footprints.

Function & Compatibility:

The EVT12S-1FT connects through the same bolted end-plate system as every other piece in the EVT12S family — four Grade 8 bolts, nuts, and washers (included) align with the standard 12-inch square end-plate geometry and torque to the same specification as any other joint in the run. At one foot, this is the spacer that gets specified when the run needs a full 12-inch extension in a single component — eliminating the need to stack multiple shorter plates and the extra bolt joints that come with them. It stacks with other EVT12S spacers and sections for compound length adjustments, and it integrates with any 12-inch plated bolt truss system sharing the same end-plate bolt pattern. Fabricated from EN AW-6061-T6 aluminum alloy under TÜV manufacturing standards with a brushed aluminum finish consistent with every other silver component in the EVT12S system.

Key Features

• One-Foot Precision Length: Adds exactly 12 inches (304.8 mm) to the truss run — the longest single spacer in the EVT12S lineup, handling a full one-foot gap in one component instead of stacking multiple shorter plates.
• 50 mm Chord Tubes & Welded Gusset Panels: Four 50 mm (1.96 in) OD / 3 mm wall main chord tubes connected by welded flat gusset panels — maintaining the 12-inch square box profile across the full one-foot span.
• Grade 8 Hardware Included: Ships with 4× Grade 8 bolts, nuts, and washers for immediate high-strength bolt-up using the standard EVT12S end-plate connection.
• 12-Inch Square End-Plate Geometry: Bolt-hole pattern and plate dimensions match EVT12S and other standard 12-inch plated bolt truss, maintaining full compatibility across the system.
• Stackable with All EVT12S Components: Combines with flat plate spacers and longer truss sections for compound length adjustments — build to any total dimension the layout requires.
• 6061-T6 Aluminum Alloy: All components fabricated from EN AW-6061-T6 — the same structural-grade aluminum used throughout the EVT12S family.
• TÜV Manufacturing Standards: Produced under TÜV-certified processes — the spacer carries the same production certification as every other component in the EVT12S catalog.
• Brushed Aluminum Finish: Standard brushed surface across all tubes and plates — visually consistent with silver EVT12S components at every joint.

Who It's For

• Solar Panel & Rooftop Framework Engineers — You're designing rooftop solar racking and equipment support frames from aluminum truss, and the structural drawing calls for a one-foot extension to reach the next roof anchor or equipment pedestal. Standard section lengths overshoot the dimension, and stacking flat plate spacers to reach 12 inches introduces multiple bolt joints where a single one-foot spacer covers the distance in one connection. The EVT12S-1FT gives you a cataloged one-foot component that lands the run on the roof anchor without field-fabricating a custom piece or accepting an over-length span that misses the attachment point.
• Conveyor & Overhead Material Handling System Builders — Your factory or distribution center uses aluminum truss to support light-duty overhead conveyors, pneumatic tube runs, or structured cable management, and you need a one-foot extension at a column transition or equipment bypass where the next standard section would overshoot the landing point. The EVT12S-1FT fills that gap in a single spacer, keeping the overhead run geometrically straight through the transition instead of stacking multiple shorter plates and multiplying the bolt joints between sections.
• Aquarium & Zoo Exhibit Structural Fabricators — You're building the structural skeleton inside large aquarium tunnels, zoo exhibit canopies, and animal habitat enclosures — overhead truss grids that fill specific spans between themed scenic panels, rockwork forms, and overhead equipment mounts in humid, chemically treated environments. A one-foot spacer fills the short spans the exhibit design creates between major structural sections in a single component — useful in structures that carry sustained dead loads from scenic elements over the months and years the exhibit operates.
• Military & Defense Portable Shelter Builders — You're fielding rapidly deployable shelters, mobile command posts, and portable equipment enclosures built on aluminum truss frames that get assembled, transported, and reassembled across multiple deployment cycles. Mission-specific equipment footprints don't always divide evenly into standard section lengths, and the one-foot spacer gives you a structural extension increment for adjusting frame dimensions in a single component without stacking multiple shorter plates and adding bolt joints that increase assembly time with every deployment cycle.
• Structural & Rigging Engineers — The EVT12S-1FT is a 1-foot (304.8 mm) 6061-T6 aluminum truss spacer with a 12-inch square profile, 50 mm OD / 3 mm wall chord tubes, and welded flat gusset panels, weighing 11.46 lbs, fabricated under TÜV manufacturing standards with Grade 8 end-plate connection hardware included. This spacer does not include diagonal bracing. It appears on an engineered drawing as a standard cataloged spacer component. Load calculations must account for the total assembled span — refer to the official EVT12S Load Tables. A licensed professional engineer must review all structures.

Designed by Evolve Truss, the EVT12S-1FT is the one-foot spacer that covers a full 12-inch gap in a single component — one spacer, one bolt-up, and the run lands where the drawing says it should.

⚠️ 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, support configuration, and the weakest component in the system. Refer to the official EVT12S Load Tables for allowable loads at all span lengths. Do not support loads directly from the spacer connection points.

Important Guidelines for Safe Use:

• Inspect all tubes, end plates, and bolt holes for deformation, cracking, or weld defects before every use.
• Ensure all Grade 8 bolts are torqued to manufacturer specifications.
• Do not mix truss components from different manufacturers unless the bolt pattern, plate dimensions, and chord alignment 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 Alignment: Ensure precise alignment across the joint to prevent uneven bolt loading.
• Mixing incompatible plated truss can compromise connection integrity and lead to structural failure.
