EVT290A-CS10 Black 10 mm (0.39 in) Male Truss Coupler Spacer.
Adds 10 mm to a 290 mm Conical Truss Connection, Finished in Matte Black.

The EVT290A-CS10 Black is a matte black, double-ended male conical aluminum spacer that adds a fixed 10 mm (0.39 in) at one compatible 290 mm truss connection. It has the same dimensional function as the standard brushed aluminum EVT290A-CS10 — 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 10 mm Spacer with a Matte Black Finish.

This is the black-finish version of the 10 mm spacer. Its dimensional function stays a fixed 10 mm addition at one compatible joint — the matte black powder coat addresses finish continuity on truss that remains exposed to view.

Fixed 10 mm Collar
Adds 10 mm (0.39 in) at one compatible joint.
Double-Ended Male Conical 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 10 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 10 mm (0.39 in) as the standard brushed aluminum EVT290A-CS10.
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-CS10 Black is used at the same connection points as the standard spacer, wherever the finished truss remains exposed to view after installation rather than concealed behind drape, ceiling elements, or building structure.

01
Theater and Stage Rigs
For exposed black overhead truss in theatrical and live production settings.
02
Studios
For black technical frames surrounding lighting, cameras, sensors, and set pieces.
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

Use It When the Truss System Needs 10 mm and the Joint Needs Black.

Select this model only when the connection actually requires 10 mm (0.39 in), the black finish is required, and the complete connection has been confirmed. Do not select a finish-matched spacer as a substitute for the correct dimensional spacer length.

Required Length
The truss system requires 10 mm (0.39 in) at the connection.
Required Finish
The installed system requires a matte black component at the exposed joint.
Confirmed Connection
Coupler, receiver, coupler-pin, and retainer engagement has been checked.
Not a Workaround
Do not use to force misaligned, damaged, or unapproved truss connections.

What's Included

One Matte Black Spacer. Retaining Hardware Sold Separately.

The EVT290A-CS10 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-CS10 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.
Connection Engagement
Confirm the selected conical coupler fully engages both receivers, and that coupler-pins and retaining hardware remain suitable for the completed joint.
Mixed-System Confirmation
Do not assume compatibility from the 290 mm classification alone. Physically test-fit the complete connection on the ground before lifting.
Finish Match Is Not a Substitute for Correct Length
Do not select this spacer for its finish alone. The connection must first require exactly 10 mm (0.39 in) at that joint; the black finish is a secondary, visual selection criterion.

Installation Conditions

Confirm the Complete Joint Before It Is Loaded or Lifted.

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 10 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 Joint
Confirm full engagement of receivers, couplers, coupler-pins, and retention hardware.
04 — Secure Hardware
Install all required coupler-pins and retainers fully and correctly before loading.

Safety Limits and Review

The Black Finish Does Not Change the Structural Boundaries.

The EVT290A-CS10 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 coupler engagement and suitable coupler-pin and retainer selection.
Have the complete structure reviewed by a licensed professional engineer.
Confirm Current Documentation Before Ordering or Installing
Confirm current manufacturer drawings, instructions, and required retaining hardware before ordering or installing the EVT290A-CS10 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-CS10 Black Frequently Asked Questions.

What is different about the Black version?

It has the same 10 mm (0.39 in) dimensional function as the standard brushed aluminum EVT290A-CS10, 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 10 mm (0.39 in); the black finish is a secondary, visual selection criterion, not a substitute for the correct dimensional length.
