EVT290A-CS30 Black 30 mm (1.18 in) Male Truss Coupler Spacer.
Adds 30 mm to a 290 mm Conical Truss Connection, Finished in Matte Black.

The EVT290A-CS30 Black is a matte black, double-ended male conical aluminum spacer that adds a fixed 30 mm (1.18 in) at one compatible 290 mm truss connection. It has the same dimensional function as the standard brushed aluminum EVT290A-CS30 — the matte black powder coat is a finish choice for truss that stays exposed to view after installation, not a functional difference. It is not a truss section, an independent support point, or a direct load-attachment location.

What It Is

A 30 mm Coupler Spacer with a Matte Black Finish.

This is the matte black version of the 30 mm spacer. Its functional role stays a fixed 30 mm addition at one compatible truss connection — the black finish supports visual continuity on truss that remains exposed to view.

Fixed 30 mm Collar
Adds 30 mm (1.18 in) at one compatible joint; it does not provide adjustable travel.
Male-to-Male Form
Provides male conical ends for compatible truss receivers.
Matte Black Powder Coat
Provides a black-finish component that matches exposed black truss.
Connection Component
It is not a truss section, support point, or direct load-attachment location.

Finish Context

Finish Is a Selection Attribute. It Is Not a Structural Difference.

Choose the black variant when the 30 mm addition is required and an exposed brushed-aluminum spacer would be visually inconsistent with the surrounding truss. The finish does not change connection requirements, load limitations, or engineering requirements.

Same Dimensional Function
Adds the same 30 mm (1.18 in) as the standard brushed aluminum EVT290A-CS30.
Visual Continuity
Keeps a matching black finish on truss that remains exposed to view after installation.
No Engineering Change
Finish selection does not alter load limitations, connection requirements, or engineering requirements.

Application Uses

Match the Finish Where the Truss Stays Exposed to View.

The EVT290A-CS30 Black is used at the same connection points as the standard brushed spacer, wherever the finished truss remains exposed to view after installation rather than concealed behind drape, ceiling elements, or building structure.

01
Theater and Club Infrastructure
For exposed black overhead truss in theatrical and live production settings.
02
Studio Systems
For black frames surrounding lighting, cameras, sensors, and set equipment.
03
Houses of Worship
For black lighting, audio, video, and display truss in architectural interiors.
04
Exhibits and Retail
For exposed black truss assemblies in branded and retail environments.

Selection Guidance

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

Select this product only when the connection actually requires 30 mm (1.18 in), the black finish is required, and the complete joint remains fully engaged with compatible receivers, conical couplers, coupler-pins, and retainers. Do not use it as an adjustable fitting, a generic extension, a repair for damaged truss, or a substitute for a different measured requirement.

Required Length
The truss system requires 30 mm (1.18 in) at the selected joint.
Required Finish
The black truss system requires a matte black component at the exposed connection.
Confirmed Connection
Coupler, receiver, coupler-pin, and retainer engagement has been checked with the 30 mm collar installed.
Not an Adjustable Coupler
Do not use to force alignment, create an unmeasured addition, or replace a required engineered connection solution.

What's Included

One Matte Black Spacer. Retaining Hardware Sold Separately.

The EVT290A-CS30 Black ships as a single double-ended male conical spacer with a matte black powder-coat finish. It does not include coupler-pins or r-clips — these must be sourced separately and matched to the completed connection.

1 Male-to-Male Spacer
A double-ended conical coupler that inserts between two compatible truss receivers.
Matte Black Powder Coat
Made from Aluminum Alloy EN AW-6061 T6 with a matte black powder-coat 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-CS30 Black 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 confirmed.
F34 Compatibility
Compatible with matching F34 290 mm square dimensions and conical hardware when the interfaces and full coupler engagement match.
Full Coupler Engagement
Confirm the selected conical coupler is long enough to fully engage both truss receivers after the 30 mm spacer is installed.
Mixed-System Confirmation
Test-fit mixed-brand or separately sourced components on the ground before lifting the completed structure.
Finish Match Is Not a Substitute for Correct Length
Do not select this spacer for its finish alone. The connection must first require exactly 30 mm (1.18 in) at that joint; the black finish is a secondary, visual selection criterion.

Installation Conditions

Confirm the Black 30 mm Joint Before It Enters Service.

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

01 — Confirm Requirement
Confirm the 30 mm addition and black-finish requirement at the specific joint.
02 — Inspect Components
Do not use damaged, deformed, cracked, or incompatible components.
03 — Test-Fit the Full Joint
Confirm complete engagement of receivers, couplers, coupler-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 Black Finish Does Not Change the Structural Boundaries.

The EVT290A-CS30 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.
Confirm full conical coupler engagement and suitable coupler-pin and retainer selection.
Have the complete structure reviewed by a licensed professional engineer.

Variant Relationship

The Dimension Comes First. The Finish Comes Second.

Choose the spacer whose fixed length matches what the connection requires. Use the brushed CS30 where a black finish is not required by the installation.

CS10 / CS10 Black
10 mm (0.39 in), brushed aluminum or matte black.
CS20 / CS20 Black
20 mm (0.79 in), brushed aluminum or matte black.
CS30
30 mm (1.18 in), brushed aluminum.
CS30 Black (This Product)
30 mm (1.18 in), matte black.
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 complete connection.
Confirm Current Documentation Before Ordering or Installing
Confirm current manufacturer drawings, instructions, and required retaining hardware before ordering or installing the EVT290A-CS30 Black. Confirm 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-CS30 Black Frequently Asked Questions.

What is different about the Black CS30?

It has the same 30 mm (1.18 in) dimensional function as the standard brushed aluminum EVT290A-CS30, finished in matte black powder coat for truss that remains exposed to view.

Are coupler-pins included?

No. The product includes the spacer only — coupler-pins and r-clips are not included and must be sourced separately.

Can I hang from this joint?

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

Should I choose this for the finish alone?

No. Select this spacer only when the connection requires exactly 30 mm (1.18 in); the black finish is a secondary, visual selection criterion, not a substitute for the correct dimensional length.
