EVT290S System Knowledge Center

When Black Truss Needs a Larger Correction,
Add 20 mm Without Introducing a Silver Joint.

The EVT290A-CS20 Black is a matte black, double-ended male conical aluminum spacer that adds a fixed 20 mm / 0.79 in at one compatible 290 mm truss connection. Select it when the approved layout requires a 20 mm correction and the exposed joint needs a black-finish component. It is not a truss section, independent support point, or direct load-attachment location.

What It Is

A 20 mm Spacer for Black-Truss Connections That Must Stay Visually Coherent.

This is the matte-black version of the 20 mm spacer. Its functional role is a fixed 20 mm correction at one compatible truss connection; its black finish supports visual continuity in exposed black-truss systems.

Fixed 20 mm Collar
Adds 20 mm / 0.79 in at one compatible joint.
Male-to-Male Form
Provides male conical ends for compatible truss receivers.
Matte Black Powder Coat
Provides a black-finish component for finish-sensitive installations.
Connection Component
It is not a truss section, support point, or direct load-attachment location.

Finish Context

A 20 mm Geometry Decision Can Also Be a Finish Decision.

Select this variant when the approved correction is 20 mm and the connection is exposed within a black-truss layout. Matte black finish does not change the structural limits or eliminate the need to verify full connection engagement.

Theater and Venue Infrastructure
For visible black overhead truss and lighting infrastructure.
Studio Systems
For black frames surrounding lighting, cameras, sensors, and scenic equipment.
Architectural Installations
For black truss used as a visible architectural or exhibit element.
Finish Boundary
Use the brushed CS20 where black finish is not required by the installation.

Selection Guidance

The Required Dimension Comes First. The Finish Must Also Match the Installation.

Select this product only when the approved correction is 20 mm / 0.79 in, the black finish is required, and the complete joint remains fully engaged with compatible receivers, conical couplers, pins, and retainers.

Required Correction
The approved layout specifies 20 mm / 0.79 in at the selected joint.
Required Finish
The black truss system requires a matte black component at the exposed connection.
Verified Geometry
Coupler, receiver, pin, and retainer engagement has been checked with the 20 mm collar installed.
No Unapproved Stacking
Do not stack, substitute, or combine spacers unless the exact arrangement is approved for the complete structure.

System Compatibility

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

The EVT290A-CS20 Black is a double-ended male conical spacer for compatible 290 mm square truss connection points. It adds 20 mm / 0.79 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 20 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

Verify the Black 20 mm Joint Before It Enters Service.

01 — Confirm Requirement
Confirm the approved 20 mm correction and black-finish requirement.
02 — Inspect Components
Do not use damaged, deformed, cracked, or incompatible components.
03 — Test-Fit Full Joint
Confirm complete engagement of receivers, couplers, pins, and retainers with the spacer installed.
04 — Secure and Inspect
Install all required hardware fully, then inspect before loading or lifting.

Safety Limits and Review

The Finish Does Not Change The Need for Complete Joint Verification.

The EVT290A-CS20 Black 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 and suitable pin and retainer selection.
Have the complete structure reviewed by a licensed professional engineer.

Product Questions

Frequently Asked Questions

What is different about the Black CS20?

It has the same 20 mm dimensional function as the brushed CS20, with a matte black powder-coat finish.

Are pins included?

No. The product includes the spacer only; coupler pins and cotter pins are not included.

Can I hang from this joint?

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