Why is a 3/8-inch spacer necessary when truss sections come in standard lengths?

Standard truss sections are manufactured in set lengths — typically measured in feet. When the total run between two rigging points, the width of a video wall frame, or the span of a booth footprint doesn't divide evenly into those standard lengths, you end up with a gap. The EVT12S-3/8IN closes that gap precisely rather than forcing an imperfect fit, over-torquing bolts to pull sections together, or accepting a misaligned connection that affects load distribution.

Does this spacer use the same connection hardware as full-length EVT12S truss sections?

Yes. The EVT12S-3/8IN uses the same end-plated nut-and-bolt connection as every other section in the EVT12S line. It ships with 4x Grade 8 bolts, nuts, and washers — the same fastener grade used across the system. The spacer bolts in between two standard truss sections the same way those sections bolt to each other.

Can I combine multiple spacers to build a custom length increment?

Yes. You can stack the 3/8-inch spacer with other EVT12S spacer sizes to reach a specific total dimension. Each spacer adds its own bolt connection, so the total assembly has more connection points than a single truss section of equivalent length. All truss systems and configurations should be reviewed by a licensed structural engineer before use.

EVT12S-3/8IN — 0.375-Inch Aluminum Truss Spacer for 12-Inch Square End-Plate Bolt Truss

EVT12S Truss Spacer Plate

3/8 Inch Aluminum Truss Spacer Plate.
Adds a 0.375 Inch Increment Between Compatible EVT12S End Plates.

The EVT12S-3/8IN is a 3/8 inch aluminum truss spacer plate for EVT12S and compatible 12 inch square end-plate bolt truss systems. It adds a documented 0.375 inch / 9.52 mm increment between properly aligned compatible end plates when standard truss section lengths do not achieve the required dimension. The spacer plate changes the overall length of a connected truss run and adds a bolted connection. It does not increase truss capacity.

Product Overview

A 3/8 Inch Truss Spacer Plate for Compatible End-Plate Connections.

The EVT12S-3/8IN is a 12 x 12 inch aluminum truss spacer plate that adds a documented 3/8 inch / 9.52 mm increment to a compatible plated truss run. Use it where a truss run requires a small added length between compatible end plates. Confirm the completed truss system, connections, support conditions, and intended use before service.

3/8 Inch Spacer Plate

Adds 0.375 in / 9.52 mm between compatible plated truss components.

Solid Aluminum Plate

Made from solid EN AW-6061 T6 aluminum in a 12 x 12 inch flat-plate format.

End-Plate Connection

Uses a compatible four-bolt end-plated nut-and-bolt connection.

Spacer Combinations

System Compatibility

Designed for EVT12S. Verify Other Brands Before Assembly.

The EVT12S-3/8IN truss spacer plate is designed for EVT12S and is identified as compatible with other standard 12 inch end-plate bolt truss systems. Exact fit with other brands is not guaranteed. Confirm end-plate dimensions, bolt-hole spacing, plate thickness, hardware, bolt engagement, required tightening specifications, and the complete truss assembly before combining components.

EVT12S Compatibility

Designed for the EVT12S 12 inch plated truss series.

Standard 12 Inch Systems

Other standard 12 inch end-plate bolt truss may require physical and technical verification before use.

Four-Bolt Connection

Verify matching end-plate dimensions and bolt-hole alignment before attempting connection.

Cross-Brand Check

Nominal 12 inch dimensions alone do not establish compatibility or suitability for the completed truss assembly.

Assembly Overview

Align the Plates. Install and Check All Four Fasteners.

The spacer plate installs between compatible plated truss components using the applicable four-bolt end-plate connection method. Assembly should be completed by personnel qualified for the truss system and according to the applicable manufacturer requirements. This overview does not provide torque values or replace approved installation instructions.

01 — Inspect Components

Inspect the spacer plate, bolt holes, mating end plates, bolts, nuts, washers, and connected truss for damage or deformation.

02 — Align Without Force

Position the spacer plate between properly aligned compatible plates. Do not use bolts to pull distorted or misaligned components into place.

03 — Install Hardware

Install the required four-bolt hardware arrangement with the correct parts and full engagement for the actual connection.

04 — Tighten as Specified

Tighten all fasteners using the applicable truss-system requirements and approved procedure.

05 — Check Seating

Confirm the plates are fully seated, the connected truss is aligned as required, and all fasteners are present and secured.

06 — Review Before Service

Inspect the completed truss assembly and connection count before loading, lifting, or placing the system into service.

Safety and Engineering

A Spacer Plate Adds Length. It Does Not Increase Truss Capacity.

Every spacer plate adds a bolted connection to the truss assembly. The allowable loading and suitability of the completed system depend on the truss model, span, support conditions, connection count, orientation, applied loads, suspension method, and project-specific review. Load-bearing, suspended, stacked-spacer, or other complex configurations require review by qualified structural or entertainment-rigging personnel.

Use only undamaged spacer plates, compatible truss components, and complete hardware sets suitable for the actual connection.

Inspect spacer plates, bolt holes, mating plates, bolts, nuts, washers, and connected truss before every use.

Install all required fasteners and tighten them according to the applicable manufacturer specification and approved procedure.

Do not force misaligned components together or use bolts to correct a distorted truss structure.

Stacked spacer plate configurations add joints and must be reviewed as part of the complete truss assembly.

Do not state or assume a load, span, overhead-use, or capacity rating for a configuration unless supported by authoritative documentation and project-specific review.

Truss Spacer Plate Questions

EVT12S-3/8IN Frequently Asked Questions.

Why use a 3/8 inch truss spacer plate?

It adds a documented 0.375 inch / 9.52 mm increment between compatible end plates when standard truss section lengths do not achieve the required dimension.

Does it include connection hardware?

Yes. The product source lists four Grade 8 bolts, nuts, and washers. Confirm the full hardware requirement for the actual truss assembly and every connection point.

Can multiple truss spacer plates be combined?

Yes. The source indicates the spacer can be combined with other EVT12S spacer sizes for a custom increment. Each additional spacer adds another bolted joint that must be included in review of the complete truss assembly.

Is it compatible with other brands of 12 inch plated truss?

It is listed as compatible with other standard 12 inch end-plate bolt-truss systems, but exact fit with other brands is not guaranteed. Verify all interface dimensions and hardware before assembly.
