What's the longest horizontal span I can build using only 2.5-foot sections before I need an intermediate support point?

The maximum span depends on the total load — not the section length. A run built entirely from 2.5-foot sections has the same span rating as the same length built from 5-foot or 10-foot sections because the EVT12S load tables are based on total span distance between support points. Refer to the official EVT12S load charts for your specific span and load combination, and have a licensed structural engineer review the full configuration.

How should I inspect truss components before use?

Inspect the end plates, bolt holes, main chords, and diagonal bracing for cracks, dents, bends, or weld fractures before every use. Check the powder coat for chips or exposed aluminum and touch up any bare areas to maintain corrosion protection. Ensure all Grade 8 bolts are properly torqued to manufacturer specifications. Remove any damaged component from service immediately.

EVT12S-2½FT Black — 2.5-Foot (30-Inch) Heavy-Duty Square Aluminum Truss Section for 12-Inch End-Plate Bolt Truss

EVT12S System Knowledge Center

2.5 Ft Black Square Box Truss End Plate Section.
30 Inch Straight Section for 12x12 Square End-Plated Aluminum Truss Systems.

The EVT12S-2½FT Black is a matte black 30-inch aluminum end-plate truss section for adding an intermediate 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.

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, diagonal bracing, welds, plates, holes, finish, and hardware for damage.

02 — Align

Bring compatible end plates together without forcing distorted parts.

03 — Install Hardware

Fit specified fasteners at all four locations with adequate engagement.

04 — Tighten

Follow the applicable manufacturer fastener procedure.

05 — Check Seating

Confirm 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 straight section, plate, or two-foot truss segment. A section changes the overall length and adds bolted joints; 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, diagonal braces, 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.
