EVT290A-CS70 70 mm (2.75 in) Male Truss Coupler Spacer.
Adds 70 mm to One 290 mm Conical Truss Connection.

The EVT290A-CS70 is a double-ended male conical aluminum coupler spacer that adds a fixed 70 mm (2.75 in) at one compatible 290 mm truss connection. Before installing, confirm the connection requires 70 mm and that truss receivers, conical hardware, coupler-pin length, and retaining hardware work together with the spacer installed. It is not a truss section, independent support point, or direct load-attachment location.

What It Is

A Fixed 70 mm Coupler Spacer for One Specific Connection Condition.

The EVT290A-CS70 is a single-piece, double-ended male conical spacer with a machined central collar. Its fixed 70 mm collar adds length at one compatible joint without adjustable travel.

Fixed 70 mm Collar
Adds a fixed 70 mm (2.75 in) at one selected connection.
Male-to-Male Conical Form
Provides male conical ends for compatible truss receivers.
Brushed Aluminum Finish
The brushed aluminum surface visually coordinates with standard aluminum truss systems.
Connection Component
It is not a truss section, support point, or direct load-attachment location.

What It Changes

It Adds 70 mm to One Joint. It Does Not Create a New Load Point.

The spacer adds 70 mm (2.75 in) at the selected compatible joint. It does not independently establish allowable span, load capacity, pick-point location, or support arrangement.

Changes
Adds 70 mm (2.75 in) to the selected connection length.
Does Not Change
Does not establish a load rating or support configuration for the modified structure.
Does Not Include
Does not include coupler-pins, r-clips, or other retaining hardware.
Does Not Permit
Does not permit direct load attachment or support from the spacer joint.

Application Uses

Close a Larger Measured Gap at a Single Connection.

Use the EVT290A-CS70 where a 290 mm truss system requires a fixed 70 mm addition at one connection point rather than a structural rework.

01
Custom Measurement Adjustments
Close a 70 mm gap without cutting or replacing a truss section.
02
Architectural Dimensions
Match a truss run to a measured display, exhibit, or architectural interface.
03
Technical Frame Adjustments
Adjust controlled dimensions around cameras, sensors, lighting, and display interfaces.
04
EVT290S and F34 Systems
Adjust measurements in compatible EVT290S or F34-format truss systems using matching hardware.

Selection Guidance

Select the CS70 When the Truss System Requires a 70 mm Addition.

Use the EVT290A-CS70 only when the connection requires a fixed 70 mm (2.75 in) addition. Do not use it as an adjustable fitting, a generic extension, a repair for damaged truss, or a substitute for a different measured requirement.

Measured 70 mm Difference
For a fixed 70 mm addition at one specific compatible joint.
Full Coupler Engagement
The selected conical coupler must fully engage both truss receivers after installation.
Single-Piece Selection
Use the correct single-piece spacer rather than combining smaller units.
Not an Adjustable Coupler
Do not use to force alignment or replace a required engineered connection solution.

What's Included

One Spacer. Retaining Hardware Sold Separately.

The EVT290A-CS70 includes one double-ended male conical spacer. Coupler-pins and r-clips are not included and must be selected to match the completed connection.

1 Male-to-Male Spacer
A double-ended conical coupler that inserts between two compatible truss receivers.
Brushed Aluminum
Machined from Aluminum Alloy EN AW-6082 T6 with a brushed finish.
No Retaining Hardware
Coupler-pins and r-clips are not included.

System Compatibility

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

The EVT290A-CS70 is designed for compatible 290 mm square conical truss connection points, including EVT290S and F34-style systems. Confirm receiver spacing, conical coupler dimensions, chord dimensions, coupler-pin length, retaining hardware, and the complete structural plan before combining separately sourced components.

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 dimensions and conical connection hardware when the interface fits correctly.
Full Coupler Engagement
Confirm the conical coupler fully engages both truss receivers after the spacer is installed.
Mixed-System Confirmation
Test-fit mixed-brand or separately sourced components on the ground before lifting.

Installation Checks

Confirm the 70 mm Requirement. Then Confirm the Entire Connection.

01 — Confirm Requirement
Confirm the truss system requires a fixed 70 mm addition.
02 — Inspect Components
Do not use damaged, deformed, cracked, worn, or otherwise compromised components.
03 — Test-Fit Before Lifting
Confirm spacer, receivers, coupler arrangement, coupler-pins, and retaining hardware fit with required engagement.
04 — Secure Hardware
Install all required coupler-pins and r-clips fully before loading or lifting.

Safety and Engineering

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

The EVT290A-CS70 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, 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 in both receivers after the 70 mm spacer is installed.
Use coupler-pins and retention hardware of sufficient length and suitability for the completed connection.
Have the complete structure reviewed by a licensed professional engineer.

Variant Relationship

Start With the Gap You Measured. Then Choose the Matching Spacer.

Spacer length and finish must match what the connection requires. Do not stack, substitute, or combine variants unless the exact arrangement is approved for the complete structure.

CS10 through CS30
10, 20, and 30 mm options, with select matte black variants.
CS40 through CS60

CS70 (This Product)
70 mm (2.75 in), brushed aluminum.
Do Not Combine Smaller Spacers to Reach 70 mm
A 70 mm requirement calls for this single-piece spacer, not a combination of smaller 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-CS70. Confirm compatibility with the specific 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.
