Straight Section Overview

A 4.10 ft Straight Truss Section for EVT290S and F34 Builds.

The EVT290S-125 is a 1.25 m straight member for compatible 290 mm square-truss systems. It is selected when a project needs more than the standard 1 m section but does not call for a 1.5 m member. Use it for planned lighting grids, trade-show frames, stage structures, exhibit bays, display towers, and other truss runs that require this length.

4.10 ft Straight Section
Use this section where the drawing calls for a 1.25 m member between compatible truss connection points.
Between 1 m and 1.5 m
The 1.25 m length gives a build team another option when the run is longer than 3.28 ft but shorter than 4.92 ft.
Brushed Aluminum Finish
The brushed-aluminum surface coordinates with standard EVT290S and F34-style truss components in stage, display, exhibit, and event-production environments.

Length Selection

Why Choose a 4.10 ft Straight Truss Section?

A 1.25 m section is useful when the project drawing calls for a run between standard 1 m and 1.5 m sections. It can replace a combination of a 1 m member and a shorter filler where the completed layout calls for a single 1.25 m section.

Add a 1.25 m Run
Use the 4.10 ft section when the drawing calls for a 1.25 m addition to a grid, frame, perimeter, header, entry opening, or support structure.
Plan Around the Drawing
Select the straight-section length called for in the project drawing, then confirm corners, bases, supports, accessories, and connection hardware for the complete build.
Combine System Components
Pair this member with compatible EVT290S straight sections, corners, base plates, and other components required for the planned structure.

Applications

A 1.25 m Member for Lighting, Trade-Show, and Stage Systems.

Use the EVT290S-125 wherever a compatible truss build calls for a 1.25 m / 4.10 ft section. The completed structure determines the required supports, rigging method, loads, and accessories.

Modular Lighting Grids
Add a 1.25 m section to a planned lighting grid or perimeter built from compatible square-truss components.
Trade-Show Structures
Build booth frames, headers, entry structures, display bays, and branded environments around the required truss run.
Stage Frameworks
Use within planned scenic frames, goalposts, presentation structures, and stage architecture where the drawing calls for this length.
Exhibits and Displays
Use in modular display frames and exhibit structures where a 1.25 m section is required by the planned geometry.

Series Construction

290 mm Square Truss with Conical Coupler Connections.

The EVT290S-125 carries the core construction of the EVT290S series in a 1.25 m straight section: a 290 x 290 mm square profile, 50 mm main chords, 20 mm diagonal braces, EN AW-6082 T6 aluminum, brushed aluminum finish, and conical end connections.

290 mm Square Profile
The 290 x 290 mm profile is designed for compatible square-truss components with matching receiver spacing and connection interfaces.
50 mm Main Chords
Main chords measure 50 mm outside diameter with 2 mm wall thickness and provide the primary connection and accessory-attachment tubing.
20 mm Diagonal Braces
Diagonal braces measure 20 mm outside diameter with 2 mm wall thickness.
Conical Connection System
Conical couplers, coupler pins, and r-clips create the mechanical interface between compatible truss sections.

Included Connection Hardware

What Ships with the EVT290S-125.

Each straight section ships with the connection hardware used to join it to compatible conical-receiver components. Confirm the project component schedule before assembly; a finished structure may also require longer sections, corners, base plates, clamps, ballast, rigging hardware, and other project-specific items.

4 Conical Couplers
Couplers create the mechanical connection between the section and compatible receiver ends.
8 Coupler Pins
Pins secure the couplers after the mating components have been aligned and fully seated.
8 R-Clips
R-clips retain each fully seated coupler pin and must be installed before the structure is moved or loaded.

System Compatibility

Match the Truss Profile and Connection Before You Build.

The EVT290S-125 is intended for compatible EVT290S, F34, and matching 290 mm square-truss systems using conical connections. Similar appearance alone does not establish compatibility. Confirm the receiver spacing, coupler fit, chord spacing, alignment, and applicable system documentation before assembly.

Receiver Spacing
All four receiver positions should align without pulling, spreading, or forcing the truss faces together.
Coupler Seating
Use couplers that match the receiver interface of both connected components and verify even seating before installing pins.
1.96 in / 50 mm Clamp Fit
The 1.96 in / 50 mm OD main chords accept compatible clamps for approved equipment and accessory attachment.
Mixed Components
When components come from different sources, confirm physical fit and applicable engineering information before using them together.

Related System Components

Add the Accessories Required by Your Configuration.

The EVT290S-125 fits within a broader 290 mm truss system. Related components should be selected separately according to the planned structure and approved application; their product pages carry their own fit, use, and working-load information where applicable.

Matching Truss Components
Add compatible straight sections, corners, base plates, and connection hardware to complete the required truss layout.
1.96 in / 50 mm Clamps
Use compatible clamps for approved lighting, equipment, and accessory attachment to the main chords.
Rigging and Retention
Select truss picks, slings, shackles, and safety cables from their individual product data and the requirements of the complete rigging plan.
Ground-Support Components
Select base plates, ballast, and related support components according to the completed structure and its reviewed requirements.

Connection and Inspection

Confirm Fit First. Then Seat, Pin, and Retain.

Once receiver spacing and compatible hardware are confirmed, assemble the connection in this order. Prepare the current project drawing, compatible mating components, supplied connection hardware, and approved support or rigging plan. Assemble on a stable work surface with access to inspect every receiver and pin location.

01 — Inspect Components
Inspect the section, receiver ends, couplers, pins, and r-clips. Do not use bent, cracked, worn, or damaged components.
02 — Insert Couplers
Place the four conical couplers into the receiver positions and confirm that they sit correctly.
03 — Align the Truss Faces
Bring the mating component into position evenly. The truss faces should close without excessive force.
04 — Pin and Retain
After alignment is confirmed, install every coupler pin fully and fit an r-clip to every pin before moving, lifting, rigging, or loading the structure.
If a Connection Does Not Close
Stop assembly. Check receiver spacing, coupler fit, damage, debris, and alignment. Do not force the truss, modify components, or drive a pin against resistance. Resolve the cause before the structure is moved or loaded.

Engineering Reference

F34 Load-Span Information Applies to the Completed Truss Run.

Compatible F34 load-span tables are available as a general reference for simply supported truss runs up to 39.4 ft / 12 m. The tables address the completed truss configuration—not an individual EVT290S-125 straight section—and should be used only with the applicable engineering notes, connection requirements, and project review.

Published Load Cases
Reference tables identify uniformly distributed loads, center-point loads, third-point loads, and quarter-point loads for applicable simply supported F34 truss spans.
Panel-Point Loading
Attach loads only at approved truss panel points. Do not assume that an arbitrary position along a chord is an approved load-attachment point.
Loads Are Not Additive
Published load cases are alternatives, not values to combine. Evaluate the actual span, support condition, load location, and load type using applicable engineering information.
Engineer Review Required
The engineering reference is general guidance only. Each finished truss structure, lighting plot, and use must be reviewed as required for the specific project by a licensed professional engineer.

System Responsibility

Capacity Comes from the Completed Configuration.

This 4.10 ft / 1.25 m section does not establish an independent span or load rating for a finished structure. Determine capacity from the complete arrangement, including connected components, span, orientation, supports, attachment locations, rigging method, applied loads, and environmental exposure. Use applicable manufacturer load tables and engineering information for the system being built.

Do not load an unverified connection point or treat one section as proof of capacity for the larger structure.
Attach loads only at approved truss panel points. Do not assume that an arbitrary position along a chord is an approved loading location.
Published load cases are not additive. Evaluate the actual span, support condition, load location, and load type using applicable engineering information for the completed truss run.
Do not use bridles unless they have been approved in writing by a licensed structural engineer. Dynamic or shock loads require separate consideration.
Inspect every coupler, pin, r-clip, clamp, sling, shackle, safety cable, and attachment point before use. Replace damaged, worn, or improperly fitting parts.
Use trained personnel and obtain the project review required for suspended, public-facing, outdoor, load-bearing, or otherwise regulated truss systems.
Documentation and Project Review
Product specifications, included hardware, compatibility information, and availability are subject to change without notice. Verify current product drawings, manufacturer instructions, connection hardware, and applicable engineering information before ordering, assembling, or using this product. This page does not approve a particular truss layout, span, loading condition, rigging plan, support arrangement, outdoor installation, or public-facing structure. For suspended, load-bearing, public-facing, outdoor, or otherwise regulated truss systems, obtain the project-specific review required by the applicable authority and a licensed structural engineer.
