EVT290A-CS10 10 mm (0.39 in) Male Truss Coupler Spacer.
For Adjusting 290 mm Conical Truss Connections.

The EVT290A-CS10 is a double-ended male conical spacer that adds 10 mm (0.39 in) at a single compatible connection point in a 290 mm truss system. It is used to close small measurement gaps and fine-tune custom measurements without altering the truss chords themselves. The spacer modifies one connection — it does not act as a truss section, a load point, or an independent support.

What It Changes

It Adds 10 mm to a Connection. It Does Not Create a New Load Point.

The spacer adds 10 mm (0.39 in) at the selected, compatible joint. It does not independently establish allowable span, load capacity, pick-point location, or support arrangement for the modified structure.

Changes
Adds 10 mm (0.39 in) to the selected connection length.
Does Not Change
Does not establish a load rating or support configuration for the modified structure.
Does Not Include
Does not include coupler-pins, r-clips, or other retaining hardware.
Connection Component
Modifies one connection — it is not a truss section or an independent support point.

Application Uses

Adjust Small Measurement Differences Without Altering Truss Chords.

The EVT290A-CS10 is used wherever a 290 mm truss system comes up 10 mm short or long at a single connection point. Confirm the approved truss system, receiver spacing, and complete support arrangement before adding a spacer to any connection.

01
Custom Measurement Adjustments
Close a verified 10 mm gap in a 290 mm truss system without cutting or replacing a truss section.
02
Fine Span Adjustments
Fine-tune an overall span measurement where standard truss lengths land just short of the target.
03
Retrofit and Rework
Adjust an existing truss system to accommodate a new fixture, wall, or structural obstruction.
04
EVT290S and F34 Truss Systems
Adjust measurements in EVT290S or F34-format 290 mm square truss systems using matching hardware.

What's Included

One Spacer. Retaining Hardware Sold Separately.

The EVT290A-CS10 ships as a single double-ended male conical spacer. It does not include coupler-pins, r-clips, or other retaining hardware — these must be sourced separately and matched to the completed connection. Confirm the current product package before ordering.

1 Male-to-Male Spacer
A double-ended conical coupler that inserts between two compatible truss receivers.
Brushed Aluminum
Made from Aluminum Alloy EN AW-6061 T6 with a brushed aluminum finish.
No Retaining Hardware
Coupler-pins and r-clips are not included and must be selected to match the completed connection.
Matches Standard Tubing
The 50 mm outer diameter matches standard 290 mm truss tubing.

System Compatibility

EVT290S, F34, and Matching 290 mm Square Conical Truss Systems.

The EVT290A-CS10 is a double-ended male conical spacer for compatible 290 mm square truss connection points. Compatibility with other components requires matching receiver spacing, conical coupler dimensions, chord dimensions, coupler-pin length, retaining hardware, and engineering data for the completed structure.

EVT290S Compatibility
Designed to integrate with compatible EVT290S sections, corners, bases, and accessories when the complete connection is physically verified.
F34 Compatibility
Compatible with matching F34 290 mm square dimensions and conical hardware when the interfaces and full coupler engagement match.
Connection Engagement
Verify the selected conical coupler fully engages both receivers, and that coupler-pins and retaining hardware remain suitable for the completed joint.
Mixed-System Verification
Compatibility requires matching interfaces and a physical ground test-fit of the complete connection before lifting.
Start With the Gap You Measured — Then Choose the Matching Spacer
Spacer length and finish must match the approved requirement. Do not stack multiple spacers at one connection point without specific engineering approval for the completed connection.

Installation Conditions

Verify the Joint Before It Is Loaded or Lifted.

Installation requires a verified truss system, serviceable parts, correct hardware, and a complete inspection before the connection is put into service.

01 — Confirm Requirement
Verify that the approved truss system calls for a 10 mm adjustment at the specific joint.
02 — Inspect Components
Do not use damaged, deformed, cracked, or incompatible components.
03 — Test-Fit the Joint
Confirm the spacer, receivers, couplers, coupler-pins, and retainers achieve required engagement.
04 — Secure Hardware
Install all required coupler-pins and retaining hardware fully and correctly before loading.

Safety Limits and Review

A Spacer Changes the Connection. It Does Not Remove Engineering Responsibility.

The EVT290A-CS10 is a structural connection component. It does not establish a load rating for the modified structure. Do not exceed the capacity of the spacer or the truss system it modifies, and do not support loads directly from the spacer connection point.

Do not exceed the capacity of the spacer or the truss system it modifies.
Do not attach or support loads directly from the spacer connection.
Verify complete coupler engagement in both receivers after the spacer is installed.
Use suitable coupler-pins and retention hardware for the completed connection.
Have the complete structure reviewed by a licensed professional engineer.
Verify Current Documentation Before Ordering or Installing
Confirm current manufacturer drawings, instructions, and required retaining hardware before ordering or installing the EVT290A-CS10. Verify compatibility with the specific EVT290I, EVT290T, EVT290S, F34-format, or EVT50ST truss components being used, and physically test-fit the complete connection on the ground before lifting. Suspended, public-facing, outdoor, or other load-bearing structures using this spacer require project-specific review by a licensed professional engineer before use.

Product Questions

EVT290A-CS10 Frequently Asked Questions.

What does the EVT290A-CS10 actually do?

It adds 10 mm (0.39 in) at a single connection point in a 290 mm truss system, adjusting small measurement differences without cutting or replacing a truss section.

Does it include coupler-pins or r-clips?

No. The spacer does not include coupler-pins, r-clips, or other retaining hardware — these must be sourced separately and matched to the completed connection.

Can I hang from this joint?

No. Do not support loads directly from the spacer connection point.

Can I stack multiple spacers to close a larger gap?

Do not stack multiple spacers at one connection point without specific engineering approval for the completed connection.
