EVT50A-S170 170 mm / 6.69 in Female Truss Spacer.
A Female-to-Female Spacer for 50 mm Tubing and Modular 290 mm Conical Truss Builds.

The EVT50A-S170 is a 170 mm / 6.69 in female-to-female aluminum truss spacer for compatible 50 mm / 2 in tubing and 290 mm conical truss systems. Its receiver holes on both ends create a fixed spacing bridge between adjoining compatible female truss ends. The spacer changes connection geometry at one joint; it is not a truss section, independent support point, or direct load-attachment location. Connecting hardware is not included; see the Technical Reference for required connection hardware. Verify fit, full coupler seating, pin engagement, retention, and the complete engineered structure before lifting or applying load.

Product Overview

A 170 mm Female Spacer for One Compatible 50 mm Tube and 290 mm Conical Truss Connection.

The EVT50A-S170 is a female-to-female spacer with receiver holes at both ends. It creates a fixed 170 mm / 6.69 in spacing bridge in a compatible 50 mm tubing and 290 mm conical truss assembly. The female receiver configuration interfaces with compatible conical connection hardware; consult the Technical Reference for the required hardware for one connection.

Fixed 170 mm Spacing
Adds a fixed 170 mm / 6.69 in bridge at one selected connection. It does not provide adjustable travel or telescoping length.
Female-to-Female Receivers
Receiver holes on both ends interface with compatible conical connection hardware and adjoining female truss receivers.
Brushed Aluminum Finish
A brushed aluminum finish designed to visually integrate with standard aluminum truss components.
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 170 mm at One Joint. It Does Not Establish a New Structural Rating.

When installed in a compatible conical connection, the spacer creates a fixed 170 mm / 6.69 in bridge between adjoining truss ends. 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 170 mm / 6.69 in bridge between adjoining compatible female truss ends.
Does Not Change
Does not independently establish a load rating, allowable span, pick-point location, or support plan.
Connection Hardware
Connecting hardware is not included. Refer to Technical Reference for the required hardware for one completed connection.
Does Not Permit
Does not permit direct attachment or support of loads from the spacer connection point.

Selection Guidance

Select the S170 When The Layout Requires a 170 mm Female-to-Female Bridge.

Use the EVT50A-S170 when the documented layout requires a fixed 170 mm / 6.69 in spacing bridge between compatible female truss ends and calls for a female-to-female receiver configuration. 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 170 mm Difference
Use when the approved layout identifies a fixed 170 mm correction at one specific compatible connection.
Female Receiver Requirement
Use where the system requires a receiver-to-receiver spacer configuration within a compatible conical truss connection.
Custom Layout Alignment
Use in a reviewed scenic, exhibit, architectural, lighting, or technical layout where 170 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

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

The EVT50A-S170 is designed for compatible 50 mm / 2 in tubing and 290 mm conical-connector truss systems, including F34 and EVT290S. Before mixing brands or separately sourced components, verify actual receiver spacing, conical-coupler dimensions, chord geometry, pin alignment, full seating, and the complete structural plan.

EVT290S Compatibility
Designed to integrate with compatible EVT290S components when the complete connection is properly selected, fitted, and installed.
F34 Compatibility
Compatible with F34 290 mm square geometry and matching conical connection hardware when the actual interface fits correctly.
Connection Fit Check
Verify the selected connection hardware fully fits and seats in the female spacer receiver and adjoining truss receiver.
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 170 mm Requirement. Then Verify the Complete Connection.

The female spacer creates a bridge within a conical truss connection. Install it only after confirming the required 170 mm correction, inspecting the components, test-fitting the connection, and verifying full seating, pins, retention hardware, and the complete structural plan.

01 — Confirm the Correction
Confirm that the approved layout requires a fixed 170 mm / 6.69 in bridge at the selected connection.
02 — Inspect Both Receivers
Inspect the spacer receiver holes and adjoining truss receiver for damage, deformation, wear, or elongation before use.
03 — Confirm Hardware
Review the Technical Reference and select the connection hardware required for the compatible system and completed connection.
04 — Test-Fit Before Lifting
Confirm the compatible conical connection seats fully in the female spacer receiver and associated truss receiver without forcing the connection.
05 — Install Retaining Hardware
Install the pins and retaining hardware required by the completed connection configuration.
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 EVT50A-S170 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 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 female spacer connection point.
Do not use the spacer to force a misaligned connection or compensate for damaged truss components.
Verify the selected conical connection fully seats in both the female spacer receiver and adjoining truss receiver.
Install the pins and retention hardware required by the completed connection before lifting or applying load.
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.

Product Questions

Frequently Asked Questions.

What does the EVT50A-S170 do?

It creates a fixed 170 mm / 6.69 in female-to-female spacing bridge between compatible truss ends within a compatible conical truss connection.

Is connecting hardware included?

No. The spacer is supplied without connecting hardware. See Technical Reference for the required hardware per connection.

What tubing and truss systems does it fit?

It is designed for compatible 50 mm / 2 in tubing and 290 mm conical truss systems, including F34 and EVT290S. Verify physical fit and the complete connection before use.

Can it be used as a load point?

No. Do not attach or support loads directly from the spacer connection point. The complete structure must be evaluated for the actual installation.

Can I combine this spacer with other spacers?

Do not stack or combine spacers unless the exact configuration has been approved for the complete structure. A combined arrangement changes connection geometry and requires review.

How much does it weigh?

The listed product weight is 1.22 lb / 0.55 kg.
