Is the matte black finish consistent with black truss sections from the EVT290S line?

Yes. The matte black powder coat on the EVT50A-S305 Black is the same finish type applied to black EVT290S truss sections. When installed between two black truss ends with male couplers, the spacer blends visually with the rest of the structure without a noticeable color or texture difference at the joint.

What hardware do I need to install this spacer into a truss run?

The EVT50A-S305 Black is a female-to-female component with receiver holes on both ends. You need two male conical couplers (sold separately) to connect it — one on each side. Each coupler seats into the spacer receiver and locks with a tapered pin and R-clip, the same connection method used across all 290mm conical truss joints.

Do I need a structural engineer to approve my truss layout?

Yes. All truss structures must be reviewed and approved by a licensed professional engineer before use. Load capacity depends on the full system configuration, total span, and loading conditions — not just individual sections or spacers.

Product Overview

A 305 mm Black Female Spacer for One Compatible 50 mm Tube and 290 mm Conical Truss Connection.

The EVT50A-S305 Black is a female-to-female spacer with receiver holes at both ends. It adds a fixed 305 mm / 12 in bridge between compatible female truss ends in a 50 mm tubing and 290 mm conical truss assembly. The receiver configuration is used with compatible conical connection hardware selected for the complete connection.

Fixed 305 mm Spacing

Adds a fixed 305 mm / 12 in bridge at one selected connection. It does not provide adjustable travel or telescoping length.

Female-to-Female Receivers

Receiver holes on both ends work with compatible conical connection hardware and adjoining female truss receivers.

Matte Black Finish

A matte black powder-coat finish for black truss layouts and environments where silver hardware may be visually distracting.

Connection Component

Used at one connection; it is not a truss section, separate support, or direct attachment location for loads.

Finish Context

Black Finish Is a Selection Attribute. It Does Not Change the Spacer Function.

Choose the black version where the installation uses exposed black tube, black truss, or black accessories. The matte black powder-coat finish supports visual continuity in finish-sensitive and low-glare layouts. Finish selection does not change the 305 mm spacing, female receiver form, or the need to verify the complete connection before use.

Visual Continuity

Helps maintain a matching appearance in exposed black truss and accessory layouts.

Same Connection Function

Adds the same fixed 305 mm / 12 in bridge as the brushed-aluminum version.

Finish Care

Handle coated components carefully to help avoid cosmetic damage to the visible finish.

What It Does

It Adds 305 mm at One Connection. Confirm the Complete Installation.

When installed in a compatible conical connection, the spacer adds a fixed 305 mm / 12 in bridge between adjoining truss ends. Confirm the complete assembly after adding the spacer, including the intended span, support arrangement, hardware selection, and installation requirements.

Adds Spacing

Adds a fixed 305 mm / 12 in bridge between adjoining compatible female truss ends.

Hardware Not Included

Choose compatible conical connection hardware for the verified interface and completed connection.

Use at One Connection

Use the spacer where the documented layout calls for a 305 mm bridge at a compatible connection.

Not a Load Attachment

Do not attach or support loads directly from the spacer connection point.

Selection Guidance

Select the Black S305 When The Layout Requires a 305 mm Female-to-Female Bridge and a Black Finish.

Use the EVT50A-S305 Black when the documented layout requires a fixed 305 mm / 12 in spacing bridge between compatible female truss ends, a female-to-female receiver configuration, and a matte black finish. 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 305 mm Difference

Use when the layout identifies a fixed 305 mm correction at one specific compatible connection.

Black Truss Layouts

Use where a matte black spacer supports visual continuity in black truss, theater, studio, scenic, or low-glare installations.

Female Receiver Requirement

Use where the layout requires a receiver-to-receiver spacer configuration within a compatible conical truss connection.

Not an Adjustable Coupler

Do not use to force alignment, create an unmeasured correction, or replace the specified connection solution.

System Compatibility

50 mm Tubing and Compatible 290 mm Conical Truss Systems.

The EVT50A-S305 Black is designed for compatible 50 mm / 2 in tubing and modular 290 mm conical-connector truss systems. Nominal truss size alone does not confirm fit. Before combining components, verify actual receiver spacing, conical-coupler dimensions, chord placement, pin alignment, full seating, retaining hardware, and the complete installation plan.

Receiver Fit Check

Verify selected connection hardware fully fits and seats in the spacer receivers and adjoining truss receivers.

Mixed-System Verification

Test-fit mixed-brand or separately sourced components on the ground before lifting and verify the completed connection.

Layout Review

Confirm that the 305 mm bridge is included in the documented layout before installation.

Current Documentation

Confirm current drawings, instructions, hardware requirements, and complete-system information before ordering or installation.

Installation Checks

Confirm the 305 mm Requirement. Then Verify the Complete Connection.

The female spacer adds a bridge within a conical truss connection. Install it only after confirming the required 305 mm correction, inspecting components, test-fitting the interface, and verifying full seating, pins, retaining hardware, and the complete installation plan. Handle the matte black finish carefully to help avoid cosmetic damage.

01 — Confirm the Correction

Confirm that the documented layout requires a fixed 305 mm / 12 in bridge at the selected connection.

02 — Inspect Both Receivers

Inspect spacer receiver holes and adjoining truss receivers for damage, deformation, wear, or elongation.

03 — Confirm Hardware

Select hardware appropriate to the verified compatible system and complete connection.

04 — Test-Fit Before Lifting

Confirm the conical connection seats fully in the spacer and associated truss receiver without forcing.

05 — Install Retaining Hardware

Install all pins and retaining hardware required by the complete connection configuration.

06 — Inspect the Assembly

Verify the completed connection and surrounding assembly against the documented plan before applying load or lifting.

Safety and Use Limits

The Spacer Adds Spacing at One Connection. Confirm the Complete Installation.

The EVT50A-S305 Black is used at a truss connection. It does not by itself establish limits for an installation that includes the spacer. Do not attach or support loads directly from the spacer connection point. Check the complete assembly, including the spacer connection, before the installation is loaded or lifted.

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 that selected compatible conical hardware fully seats in both the spacer receiver and adjoining truss receiver.

Install all pins and retaining hardware required by the complete connection before lifting or applying load.

Do not use fewer connectors, pins, or retainers than the documented connection configuration requires.

Do not stack or combine spacers unless the exact arrangement is included in the documented installation plan.

Obtain qualified review for the complete installation where required.
