EVT290A-CS30 Black 30 mm / 1.18 in Truss Spacer.
A Matte Black Male-to-Male Conical Spacer for Modular 290 mm Truss Builds.

The EVT290A-CS30 Black is a double-ended male conical aluminum spacer that adds a fixed 30 mm / 1.18 in at one compatible 290 mm square truss connection. Its matte black powder-coat finish supports black-finish truss layouts where a silver spacer would be visually distracting. The spacer changes connection geometry at one joint; it is not a truss section, independent support point, or direct load-attachment location. Confirm full coupler engagement, pins, retention hardware, and the complete engineered structure before lifting or applying load.

Product Overview

A Fixed 30 mm Spacer for One Compatible 290 mm Conical Truss Connection.

The EVT290A-CS30 Black is a single-piece male-to-male conical spacer with an integrated 30 mm collar. It inserts into compatible conical receivers between adjoining 290 mm square truss sections and creates a fixed 30 mm / 1.18 in correction at that joint. The matte black finish helps maintain visual continuity in black-truss, theater, club, house-of-worship, studio, scenic, and exhibit installations.

Fixed 30 mm Collar
Adds a fixed 30 mm / 1.18 in at one selected connection. It does not provide adjustable travel or telescoping length.
Male-to-Male Conical Form
Provides male conical ends for insertion into the receivers of adjoining compatible truss sections.
Black-Finish Integration
The matte black powder coat supports finish continuity where exposed silver connection hardware is visually undesirable.
Connection-Level Component
The spacer changes one joint. It is not a truss section, separate support point, or direct load-attachment location.

What It Changes

It Adds 30 mm at One Joint. It Does Not Establish a New Structural Rating.

When installed in a compatible conical connection, the spacer increases the effective length at the selected joint by 30 mm / 1.18 in. It does not independently establish allowable span, load capacity, pick-point location, support arrangement, or approval for the modified structure. Evaluate the complete system after the connection geometry has changed.

Changes
Adds a fixed 30 mm / 1.18 in to the effective length of one selected truss connection.
Does Not Change
Does not independently establish a load rating, allowable span, pick-point location, or support plan.
Does Not Include
The product source identifies the 30 mm spacer coupler only. Coupler pins and cotter pins are not included.
Does Not Permit
Does not permit direct attachment or support of loads from the spacer connection point.

Selection Guidance

Select the Black CS30 When The Layout Requires a 30 mm Correction and a Black Finish.

Use the EVT290A-CS30 Black when the documented layout requires a fixed 30 mm / 1.18 in correction at one compatible 290 mm conical truss joint and a matte black finish is preferred. Do not use it as an adjustable fitting, a generic extension, a repair for damaged truss, or a substitute for a different measured correction.

Measured 30 mm Difference
Use when the approved layout identifies a fixed 30 mm correction at one specific compatible connection.
Black Truss Systems
Use where a matte black connection accessory helps maintain the visual appearance of a black truss layout.
Custom Layout Alignment
Use in a reviewed scenic, exhibit, architectural, lighting, or technical layout where 30 mm is the required correction.
Not an Adjustable Coupler
Do not use to force alignment, create an unmeasured correction, or replace a required engineered connection solution.

System Compatibility

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

The EVT290A-CS30 Black is designed for compatible 290 mm square conical truss connection points, including EVT290S and F34-style systems. Verify the actual receiver spacing, conical coupler dimensions, chord geometry, pin length, retaining hardware, and complete structural plan before combining separately sourced components or lifting the completed structure.

EVT290S Compatibility
Designed to integrate with compatible EVT290S square truss sections, corners, bases, and accessories when the complete connection is physically verified.
F34 Compatibility
Compatible with matching F34 290 mm square geometry and conical connection hardware when the interface fits correctly.
Full Coupler Engagement
Verify that the selected conical coupler is long enough to fully engage both truss receivers after the 30 mm spacer is installed.
Mixed-System Verification
Test-fit mixed-brand or separately sourced components on the ground before lifting and verify the completed connection and structure.

Installation Checks

Confirm the 30 mm Requirement. Then Verify the Entire Connection.

The spacer changes the effective length and connection depth at one joint. Install it only after confirming the required 30 mm correction, inspecting the components, test-fitting the connection, and verifying coupler engagement, pins, retention hardware, and the complete structural plan.

01 — Confirm the Correction
Confirm that the approved layout requires a fixed 30 mm / 1.18 in correction at the selected connection.
02 — Inspect Components
Do not use damaged, deformed, cracked, worn, or otherwise compromised spacers, truss receivers, couplers, pins, or retaining hardware.
03 — Test-Fit Before Lifting
Confirm that the spacer, receivers, coupler arrangement, pins, and retaining hardware fit together with required engagement.
04 — Verify Coupler Engagement
Confirm that the selected conical coupler fully engages both truss receivers after the 30 mm spacer is added.
05 — Install Retaining Hardware
Supply and install the required pins and cotter pins. They are not included with the spacer coupler.
06 — Inspect the Complete Structure
Verify the completed connection and surrounding structure against the approved plan before any load is applied or the structure is lifted.

Safety and Engineering

The Spacer Changes Connection Geometry. It Does Not Override System Limits.

The EVT290A-CS30 Black is a structural connection component. It does not independently establish a load rating for the modified structure. Do not exceed the capacity of the spacer or the truss system it modifies. Do not support loads directly from the spacer connection point. Review the complete structure—including the modified joint—for the actual installation.

Do not exceed the capacity of the spacer or the truss system it modifies.
Do not attach or support loads directly from the connection where the spacer is installed.
Do not use the spacer to force a misaligned connection or compensate for damaged truss components.
Verify full conical coupler engagement in both receivers after the spacer is installed.
Use pins and cotter pins of sufficient length and suitability for the completed connection geometry.
Do not use fewer connectors, pins, or retainers than the approved connection configuration requires.
Test-fit mixed-brand connections on the ground before lifting.
Have the complete structure reviewed by a qualified authority or licensed professional engineer where required.
