What It Is

A Fixed 50 mm Spacer for Standard 290 mm Conical Truss Connections.

The EVT290A-CS50 is a single-piece, double-ended male conical spacer with an integrated 50 mm collar. It connects standard 290 mm square conical truss systems, including EVT290S and F34, while adding a fixed 50 mm / 1.97 in adjustment at the selected joint.

Fixed 50 mm Collar
The collar adds a fixed 50 mm / 1.97 in dimension. It does not provide adjustable travel or telescoping length.
Male-to-Male Connection Form
The component provides male conical ends for insertion into the receivers of adjoining standard 290 mm conical truss sections.
50 x 130 x 50 mm Envelope
The documented component dimensions are 50 x 130 x 50 mm. Use the current technical drawing for the exact layout review.
Connection-Level Component
The spacer modifies one joint. It is not a truss section, a separate support point, or a direct load-attachment location.

What It Changes

It Adds 50 mm at One Joint. It Does Not Establish a New Structural Rating.

When installed in a standard 290 mm square conical truss connection, the spacer increases the effective length at the selected joint by 50 mm / 1.97 in. This is a fixed correction within the CS spacer family. It does not independently establish allowable span, load capacity, pick-point location, or support arrangement for the modified structure.

Changes
Adds 50 mm / 1.97 in to the effective length of one selected connection.
Does Not Change
Does not independently establish a load rating, allowable span, pick-point location, or support arrangement.
Does Not Include
Does not include coupler pins, cotter pins, or other retaining hardware.
Does Not Permit
Does not permit direct attachment or support of loads from the spacer connection point.

Selection Guidance

Select the CS50 When The Layout Requires a 50 mm Correction.

Use the EVT290A-CS50 when the documented layout requires a fixed 50 mm / 1.97 in correction at one standard 290 mm conical truss joint. Do not use it as an adjustable fitting or as a substitute for a smaller correction. Select the spacer length that matches the measured layout requirement.

Measured 50 mm Difference
Use when the planned layout identifies a fixed 50 mm correction at one selected joint.
Custom Architectural Dimensions
Use where a standard 290 mm truss run must meet a measured scenic, exhibit, architectural, or technical interface.
Large Fixed Adjustment
Use where the 50 mm connection-length correction is required to close the intended truss span.
Not an Adjustable Coupler
Do not use to create an unmeasured correction, force a damaged joint, or replace a required engineered connection solution.

System Compatibility

EVT290S, F34, and All Standard 290 mm Square Conical Truss Systems.

The EVT290A-CS50 is a double-ended male conical spacer designed for standard 290 mm square conical truss connection points. It adds 50 mm / 1.97 in at one connection and is compatible with EVT290S, F34, and all standard 290 mm square conical truss systems. The 50 mm collar provides a fixed, repeatable adjustment where a standard truss length does not meet the documented layout dimension.

EVT290S Compatibility
Designed to integrate with EVT290S sections, corners, bases, and accessories for a 50 mm connection-length correction.
F34 Compatibility
Compatible with F34 290 mm square truss geometry and standard conical connection hardware.
Standard 290 mm Compatibility
Compatible with all standard 290 mm square conical truss systems using standard matching conical coupler geometry.
Connection Engagement
The 50 mm spacer changes connection depth. Before lifting or applying load, verify complete receiver engagement and use the correct pins, cotter pins, and retaining hardware.
Mixed-System Verification
When joining components from different manufacturers, ground-test the complete joint before lifting to confirm seating, pin alignment, and proper retention.

Installation Checks

Seat the Joint Fully. Then Secure It Before Service.

The 50 mm collar changes the effective length and connection depth at the selected joint. Before the truss is lifted or loaded, confirm the required correction, inspect all components, fully seat the conical connection, and install the correct pins, cotter pins, and retaining hardware.

01 — Confirm the 50 mm Requirement
Confirm the planned layout requires a fixed 50 mm correction at the selected connection.
02 — Inspect the Components
Do not use damaged, deformed, cracked, worn, or otherwise compromised spacers, truss receivers, couplers, pins, or retainers.
03 — Test-Fit Before Lifting
Assemble and check the full joint on the ground before it is lifted, especially when joining components from different manufacturers.
04 — Verify Full Engagement
Confirm the male spacer ends and conical hardware are completely seated in both truss receivers.
05 — Install Pins and Cotters
Use correct pins, cotter pins, and retaining hardware for the completed connection. Pins and cotter pins are not included with the spacer.
06 — Inspect the Complete Structure
Verify the completed connection and surrounding structure against the approved plan before load is applied or the structure is lifted.

Safety Limits and Review

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

The EVT290A-CS50 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 and the modified connection 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.
Fully seat the conical joint and verify complete engagement at both truss receivers.
Use the correct pins, cotter pins, and retaining hardware for the completed connection geometry.
Do not use fewer connectors, pins, or retainers than the approved connection configuration requires.
Ground-test mixed-manufacturer joints before lifting to confirm seating, alignment, and retention.
Have the complete structure reviewed by a qualified authority as required for the actual installation.

Variant Relationship

Select the Spacer That Matches the Required Correction.

Spacer selection begins with the documented dimension at the specific joint. The 50 mm correction is not a substitute for a 10 mm, 20 mm, or 30 mm spacer. Do not stack, substitute, or combine spacer variants unless the exact arrangement is approved for the complete structure.
