EVT290S System Knowledge Center

When the Truss Layout Is Close,
But Needs 30 mm to Close Correctly.

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. Use it when an approved layout requires that exact correction at a specific joint and the complete connection—including truss receivers, conical hardware, pins, and retainers—has been verified. It is not a truss section, independent support point, or direct load-attachment location.

What It Is

One Fixed Spacer for One Specific 30 mm Fit Condition.

The EVT290A-CS30 is a single-piece, double-ended male conical spacer with an integrated 30 mm collar. It is designed for compatible 290 mm conical truss connection points when the complete physical connection is verified.

Fixed 30 mm Collar
Adds a fixed 30 mm / 1.18 in dimension; it does not provide adjustable travel.
Male-to-Male Form
Provides male conical ends for compatible receivers of adjoining truss sections.
Brushed Aluminum
Made from EN AW-6061 T6 aluminum alloy with a brushed aluminum finish.
Connection Component
Modifies one connection; it is not a truss section or independent support point.

What It Changes

It Resolves a 30 mm Layout Difference. It Does Not Create a New Load Point.

The spacer adds 30 mm / 1.18 in at the selected, compatible joint. It does not independently establish allowable span, load capacity, pick-point location, or support arrangement.

Changes
Adds 30 mm / 1.18 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, cotter pins, or other retaining hardware.
Does Not Permit
Does not permit direct load attachment or support from the spacer joint.

Selection Guidance

Use It for a Verified 30 mm Gap. Not as a General-Purpose Workaround.

Select this spacer only when a measured and approved layout requires a 30 mm correction at a compatible joint. Because it creates a larger fixed geometry change than the 10 mm and 20 mm variants, complete coupler, receiver, pin, and retainer engagement must be verified.

Measured 30 mm Gap
For a documented 30 mm correction at one specific connection.
Architectural Alignment
For a reviewed interface with measured scenic, display, or architectural conditions.
Technical Frame Geometry
For controlled dimensions around cameras, sensors, lighting, displays, and other system interfaces.
No Unapproved Stacking
Do not stack spacers or substitute combinations without approval for the complete structure.

System Compatibility

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

The EVT290A-CS30 is a double-ended male conical spacer for compatible 290 mm square truss connection points. It adds 30 mm / 1.18 in at one connection. Compatibility with other components requires matching receiver spacing, conical coupler dimensions, chord geometry, 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 geometry and conical hardware when dimensional interfaces and full coupler engagement match.
Connection Engagement
The 30 mm spacer changes connection depth. Verify complete receiver engagement and suitable pin and retention hardware.
Mixed-System Verification
Do not assume compatibility from the 290 mm classification alone. Test-fit the complete joint on the ground before lifting.

Installation Conditions

Check the 30 mm Joint Before It Leaves the Ground.

01 — Confirm Requirement
Verify the approved layout calls for a 30 mm correction at the specific connection.
02 — Inspect Components
Do not use damaged, deformed, cracked, or incompatible components.
03 — Test-Fit Full Joint
Confirm receivers, couplers, pins, and retainers achieve full required engagement with the spacer installed.
04 — Secure and Inspect
Install all required hardware fully, then inspect before the structure is loaded or lifted.

Safety Limits and Review

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

The EVT290A-CS30 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 support loads directly from the spacer connection.
Verify full conical coupler engagement in both receivers after the 30 mm spacer is installed.
Use pins and retention hardware of sufficient length and suitability for the completed geometry.
Have the complete structure reviewed by a licensed professional engineer.

Variant Relationship

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

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

Product Questions

Frequently Asked 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 required coupler, receiver, pin, and retainer engagement.

Are pins included?

No. The spacer is supplied without coupler pins and cotter pins.
