What makes the EVT12S-1FT different from the flat plate spacers in the EVT12S lineup?

The EVT12S-1FT includes main chords and diagonal bracing — it's a fully framed truss section, not a flat plate. Flat plate spacers like the 3/8-inch and 1/2-inch handle dimensional adjustments at the connection point, but they don't resist torsion or lateral forces on their own. The 1-foot section has diagonal bracing that transfers shear and lateral loads through the web, making it structurally rigid between the end plates. Use a flat plate when you're closing a fractional gap; use the 1-foot section when the application introduces lateral forces, vibration, or twisting loads at that joint.

Can I use the EVT12S-1FT as a base or top section in a vertical truss tower?

Yes. The EVT12S-1FT bolts into any position in a vertical tower — base, top, or anywhere in the middle. In a tower application, it adjusts the total column height by exactly one foot while maintaining full lateral bracing through the added section. This is useful when the trim height requirement falls between two standard full-length configurations and you need the extension to be structurally braced rather than relying on a flat plate at the top of the column.

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

EVT12S System Knowledge Center

One Foot Aluminum Truss Section.
Adds a 12 Inch Section Between Compatible End-Plate Truss Components.

The EVT12S-1FT is a 12-inch aluminum end-plate truss section for adding a one-foot length within a 12-inch end-plated box truss system. It helps configure overall run dimensions when a standard section length is too long or too short. Allowable loading depends on the completed truss system, including its span, supports, connections, and applied loads.

Product Overview

A One Foot Aluminum Section for 12 Inch End-Plated Box Truss Systems.

The EVT12S-1FT supplies a one-foot section for adding length within a 12-inch end-plated box truss system. Its 12-inch length provides an intermediate option when a standard section length is too long or too short. The listed finish is brushed aluminum.

Application Uses

For 12-Inch End-Plated Box Truss Systems.

The one-foot aluminum section may be considered for compatible lighting grids, scenic structures, trade-show displays, venue systems, touring equipment, and rental inventory where a 12-inch section is specified. The required supports, span, and loads must be evaluated for the full installation rather than inferred from this section length.

System Compatibility

For Standard 12-Inch End-Plated Truss Systems. Verify Every Connection.

The product is listed for EVT12S and other standard 12 inch end-plate bolt truss systems using compatible bolt connections, but exact fit with other systems is not guaranteed. The coating is a finish characteristic and does not establish connection compatibility. Before connecting different systems, verify end-plate dimensions and thickness, bolt-hole positions, chord alignment, hardware, fastener engagement, and completed-joint seating.

Assembly Overview

Align the End Plates. Install and Check All Four Fasteners.

Assembly should be performed by personnel qualified for the truss system in accordance with applicable manufacturer requirements. This outline provides neither torque values nor installation approval.

01 — Inspect

Check tubing, welds, plates, holes, finish, and hardware for damage.

02 — Align

Bring compatible end plates together without forcing distorted parts.

03 — Install Hardware

Fit the specified fasteners at all four locations with adequate engagement.

04 — Tighten

05 — Check Seating

Confirm the required hardware and full plate seating.

06 — Inspect Before Service

Review the completed truss system and supports before loading.

Engineering Reference

Load-Span Reference for Completed EVT12S Truss Runs.

All truss loading calculations are based on a completed compatible 12 x 12 aluminum-truss run supported or suspended at both ends, under one stated static-load alternative. The values below do not rate an individual spacer, plate, or one-foot section. A spacer or short section changes the overall length and adds a bolted joint; it does not increase the completed system’s allowable capacity.

Load-Span Assumptions and Project Review

Table assumptions: The reference evaluates unbraced truss configured as a simply supported beam. The primary analyzed spans were 10 ft, 20 ft, 30 ft, and 40 ft. If CPL, TPL, or QPL loading occurs at a truss connection, a minimum of two chords is assumed to support the vertical load.

Not included: Shock loads, dynamic loads, and resultant horizontal rigging forces, including forces from bridles or baskets. UDL applies only when the load is evenly distributed across the entire span. Published load cases are alternatives and are not additive.

Licensed structural-engineer review is required for every truss system. These values are general planning reference only and do not approve or rate an individual straight section, a completed lighting plot, a ground-support structure, a goal post, a tower, a start/finish arch, a suspended configuration, an outdoor installation, a mixed-component build, or any other assembled truss system. Confirm the complete configuration, supports, connections, span, applied loads, attachment points, rigging, ballast or anchorage, environmental conditions, and applicable code requirements with a licensed structural engineer before use.

Current documentation: Product specifications, included hardware, compatibility information, and availability are subject to change. Verify current product drawings, manufacturer instructions, connection hardware, and applicable engineering information before ordering, assembling, or using this product.

Safety and Engineering

A Truss Section Adds Length. It Does Not Increase Truss Capacity.

Allowable loading depends on the complete truss system, including span, supports, orientation, joints, suspension method, and applied loads. Suspended, load-bearing, dynamic-load, and complex applications require qualified structural or entertainment-rigging review. No stand-alone capacity value or torque value is provided here.

Inspect the truss section, welds, plates, bolt holes, hardware, and connected truss before every use.

Remove any component with cracks, bends, elongated holes, plate deformation, damaged welds, or substantial finish damage from service.

Install and tighten all required fasteners using the applicable manufacturer procedure.

Do not support loads directly from connection points without approval for the complete truss system.

Verify connection interfaces and completed-system suitability before combining different systems.

Have a competent person perform a documented inspection at least annually and remove unsafe parts from service.

Truss Section Questions

EVT12S-1FT Frequently Asked Questions.

What finish is listed for this section?

This version is listed with a brushed aluminum finish. Its listed dimensions, material, and end-plate connection format match the one-foot truss section format.

What hardware is included?

The listing identifies four Grade 8 bolts, four nuts, and four washers. Hardware finish may differ from the truss-section finish. Confirm the hardware needed at every connection in the completed system.

Can I combine it with other truss sections or spacers?

Additional compatible components may be considered, but every added joint needs its required hardware and the completed truss system must be reviewed for the intended use.

Does the section change truss capacity?

It does not increase capacity. Allowable loading depends on the complete system and its support and loading conditions.
