EVT290S System Knowledge Center

When the Layout Needs More Than a Minor Adjustment,
Add 20 mm at One Verified Connection.

The EVT290A-CS20 is a double-ended male conical aluminum spacer that adds a fixed 20 mm / 0.79 in at one compatible 290 mm truss connection. It is intended for an approved 20 mm correction where the complete joint—including receiver geometry, conical coupler engagement, pin length, and retaining hardware—has been verified. It is not a truss section, independent support point, or direct load-attachment location.

What It Is

A Fixed 20 mm Spacer for One Specific Connection Condition.

The EVT290A-CS20 is a single-piece, double-ended male conical spacer with an integrated 20 mm collar. Its documented material is EN AW-6061 T6 aluminum alloy with a brushed aluminum finish.

Fixed 20 mm Collar
Adds 20 mm / 0.79 in; it does not provide adjustable travel.
Male-to-Male Form
Provides male conical ends for compatible truss receivers.
Larger Correction
The 20 mm addition changes effective connection depth and requires full engagement verification.
Connection Component
It is not a truss section, support point, or direct load-attachment location.

What It Changes

It Adds 20 mm to One Joint. The Entire Joint Must Still Work as a Joint.

The spacer adds 20 mm / 0.79 in at the selected connection. It does not independently establish a load rating, allowable span, pick-point location, or support arrangement for the modified structure.

Changes
Adds 20 mm / 0.79 in to the selected connection length.
Does Not Change
Does not establish allowable span or a load rating for the modified system.
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

Select It Only for a Verified 20 mm Need. Do Not Treat It as Two 10 mm Decisions.

A 20 mm spacer modifies the connection as one component. Select it only when an approved layout requires a 20 mm / 0.79 in correction and the complete connection can be verified with the correct coupler, pins, retainers, and truss receivers.

Measured 20 mm Difference
For a documented 20 mm correction at one specific connection.
System Geometry
For planned grids, frames, scenic systems, and technical structures with measured interfaces.
Receiver and Coupler Check
For configurations where full dual-receiver coupler engagement remains possible.
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-CS20 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

Confirm the 20 mm Joint Before It Enters Service.

01 — Confirm Requirement
Verify the approved layout calls for a 20 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 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 20 mm Change Requires Complete Joint Verification.

The EVT290A-CS20 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 attach or support loads directly from the spacer connection.
Verify full coupler engagement in both receivers after the spacer is installed.
Use suitable pins and retention hardware for the completed 20 mm connection geometry.
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 the approved correction. Select the black version only when the same dimensional requirement also needs a black finish.

Product Questions

Frequently Asked Questions

What does the CS20 do?

It adds 20 mm / 0.79 in at one compatible 290 mm conical truss connection.

Why must engagement be checked?

The 20 mm collar changes connection depth, so the complete joint must retain required coupler, receiver, pin, and retainer engagement.

Are pins included?

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