EVT290A-CS30 30 mm Male Truss Coupler Spacer.
Adds 30 mm at One Compatible 290 mm Conical Truss Connection.

The EVT290A-CS30 is a double-ended male conical aluminum spacer that adds a fixed 30 mm / 1.18 in at one compatible 290 mm truss connection. Before installation, confirm the connection requires 30 mm and that the complete joint—including truss receivers, conical coupler, coupler-pin length, r-clip fit, and retaining hardware—will remain suitable with the spacer installed. It is not a truss section, independent support point, or direct load-attachment location.

What It Is

One Fixed Coupler Spacer for One Specific 30 mm Connection Condition.

The EVT290A-CS30 is a single-piece, double-ended male conical spacer with an integrated 30 mm collar. It is manufactured from Aluminum Alloy EN AW-6061 T6 with a brushed aluminum finish. Its fixed 30 mm geometry must match the approved requirement at the selected compatible connection.

Fixed 30 mm Collar
Adds 30 mm / 1.18 in; it does not provide adjustable travel.
Male-to-Male Form
Provides double-ended male conical interfaces for compatible truss receivers.
Brushed Aluminum
Manufactured from Aluminum Alloy EN AW-6061 T6 with a brushed finish.
Connection Component
It is not a truss section, support point, or direct load-attachment location.

What It Changes

It Adds 30 mm to One Joint. It Does Not Create a New Load Point.

The CS30 adds 30 mm / 1.18 in at the selected compatible connection. It does not independently establish a load rating, allowable span, pick-point location, or support arrangement for the modified truss structure.

Changes
Adds 30 mm / 1.18 in to the selected compatible connection length.
Does Not Change
Does not establish an allowable span or load rating for the modified structure.
Does Not Include
Does not include coupler-pins, r-clips, or other retaining hardware.
Does Not Permit
Does not permit direct load attachment or support from the spacer joint.

What the Spacer Supports

Close a Larger Measured Difference at a Single Connection.

Use the EVT290A-CS30 where a verified compatible truss connection requires a 30 mm adjustment. Confirm the receiver interface, selected coupler, required pins and r-clips, complete layout, support conditions, and applicable engineering requirements before modifying a connection.

Custom Measurement Adjustments
Address a verified 30 mm measurement difference without modifying a truss section.
Architectural Alignment
Match reviewed display and architectural interfaces with measured conditions.
Technical Frame Adjustments
Adjust controlled dimensions around planned camera, sensor, lighting, and display interfaces.
EVT290S and F34 Systems
Use with verified compatible 290 mm conical truss systems and matching retention hardware.

Selection Guidance

Use It for a Confirmed 30 mm Need. Not as a General-Purpose Workaround.

Select this spacer only when a measured system requires a 30 mm addition at a compatible joint. Because it creates a larger fixed dimension change than the 10 mm and 20 mm variants, complete coupler, receiver, coupler-pin, and r-clip engagement must be confirmed.

Measured 30 mm Difference
For a 30 mm addition at one specific verified connection.
Architectural Alignment
For a reviewed interface with measured display or architectural conditions.
Technical Frame Fit
For controlled dimensions around planned cameras, sensors, lighting, and display interfaces.
No Unapproved Stacking
Do not stack spacers or substitute combinations without approval for the completed structure.

Included Components

One Spacer. Retaining Hardware Sold Separately.

The EVT290A-CS30 ships as one double-ended male conical spacer. It does not include coupler-pins, r-clips, or other retaining hardware. Select and verify all required hardware for the completed approved connection before installation.

1 Male-to-Male Spacer
One double-ended male conical spacer inserts between compatible truss receivers.
30 mm Length Added
Adds 30 mm / 1.18 in at the selected compatible connection point.
6061-T6 Aluminum
Manufactured from Aluminum Alloy EN AW-6061 T6 with a brushed finish.
No Retaining Hardware
Coupler-pins and r-clips are not included and must be selected for the verified connection.
Do not stack spacers without specific approval.

Use the selected spacer only for the approved measurement adjustment. Do not stack multiple spacers at one connection point without project-specific engineering approval for the completed connection.

System Compatibility

Use CS30 in Compatible 290 mm Conical Truss Connections.

The EVT290A-CS30 is a double-ended male conical spacer for compatible 290 mm conical truss connections. Compatibility requires matching receiver spacing, conical coupler dimensions, chord interfaces, coupler-pin length, r-clip fit, complete engagement, and engineering data for the modified structure.

EVT290S Compatibility
Use with compatible EVT290S sections, corners, bases, and accessories when the complete connection is verified.
F34 Compatibility
Use with F34-format components only when receivers, couplers, pins, and retention hardware match.
Connection Engagement
The 30 mm spacer changes joint depth. Confirm complete receiver engagement and suitable pin and retention hardware.
Mixed-System Verification
Confirm the complete connection with a physical ground test-fit before lifting the structure.
Mechanical fit does not establish structural suitability.

A spacer can physically fit within a connection without the completed modified structure having approved support or load conditions. Verify all interfaces, documentation, hardware, and project-specific engineering before use.

Installation Overview

Check the 30 mm Joint Before It Leaves the Ground.

Install CS30 only in a verified compatible connection using serviceable components, correct pins and r-clips, current manufacturer instructions, and the approved project plan. Do not force a spacer or connection into alignment.

01 — Confirm Requirement
Confirm the approved truss system requires a 30 mm addition at the selected connection.
02 — Inspect Components
Inspect the spacer, receivers, couplers, pins, r-clips, and adjoining truss for damage or deformation.
03 — Test-Fit the Full Joint
Confirm all receivers, couplers, pins, and retainers achieve required engagement with the spacer installed.
04 — Secure and Inspect
Install required hardware fully, then inspect the complete joint before handling, lifting, or loading.

Safety and Engineering

A 30 mm Change Requires More Than an Assumption About Fit.

The EVT290A-CS30 does not independently establish a load rating for the modified structure. The spacer changes connection geometry, so evaluate the completed layout for support conditions, joint engagement, installed loads, handling method, and engineering requirements. Do not support loads directly from the spacer connection unless the exact approved load case specifically permits it.

Do not exceed the capacity of the spacer, installed connection hardware, or completed truss system.
Do not support loads directly from the spacer connection unless the exact approved load case permits it.
Verify complete coupler engagement in both receivers after the spacer is installed.
Use pins and r-clips selected for the complete verified 30 mm connection.
Do not stack spacers at one connection point without project-specific engineering approval.
Use qualified rigging or engineering review for overhead, public-facing, outdoor, load-bearing, or regulated modified structures.

Variant Relationship

Start With the Gap You Measured. Then Choose the Matching Spacer.

Spacer length and finish must match the approved connection requirement. Do not stack, substitute, or combine variants unless the exact arrangement is approved for the complete structure.

Do not combine smaller spacers to reach 30 mm.

A 30 mm requirement calls for this single-piece spacer, not a combination of 10 mm and 20 mm units. Do not stack spacers or combine dimensions without engineering approval for the completed connection.

Product Questions

EVT290A-CS30 Questions.

What does the CS30 do?

It adds 30 mm / 1.18 in at one compatible 290 mm conical truss connection.

Why is the complete joint check important?

The 30 mm collar changes connection depth, so the joint must retain suitable coupler, receiver, coupler-pin, and r-clip engagement.

Are coupler-pins included?

No. The spacer is supplied without coupler-pins or r-clips. Select them separately for the completed verified connection.

Can smaller spacers replace one CS30?

No. A 30 mm requirement calls for this single-piece spacer. Do not stack spacers or combine dimensions without engineering approval for the completed connection.
