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 System Knowledge Center

Precision 3/8-Inch Adjustment.
The Smallest EVT12S Spacer Increment.

The EVT12S-3/8IN is a 0.375-inch aluminum spacer plate designed for 12-inch square end-plate bolt truss systems. It provides a precise dimensional correction for lighting grids, LED frames, trade-show structures, architectural installations, and modular layouts where standard truss lengths leave a fractional-inch gap.

Fine-tune overall grid width, length, or trim alignment.

LED Wall Frames

Match frame dimensions to panel arrays and mounting geometry.

Trade Show Booths

Hit exact booth footprints and overhead frame dimensions.

Permanent Installations

Align truss runs with architectural steel and fixed attachment points.

Touring Systems

Correct small venue-to-venue dimensional differences without modifying truss.

Who It’s For

Built for Professionals Who Need Exact Structural Dimensions.

Best suited for teams working with 12-inch plated truss systems and engineered layouts.

Event Production Riggers

For venue-specific spans and exact stage or grid dimensions.

Lighting Designers and Integrators

For aligning grids to fixed pick points and equipment layouts.

LED Wall Framers

For matching support structures to exact display-array dimensions.

Trade Show Builders

For meeting exact booth footprint and overhead-frame dimensions.

Rental Companies

For spacer inventory that expands the number of achievable system sizes.

Engineers and Industrial Users

Included Hardware

Supplied for One Complete End-Plate Connection.

The spacer includes the standard high-strength hardware needed to connect one end plate to a compatible plated truss component.

4 Grade 8 Bolts

High-strength fasteners for the four end-plate connection points.

4 Nuts

Matching nuts for securing the supplied bolts.

4 Washers

Included to distribute clamping force at the connection.

Confirm the hardware quantity required for the complete structure.

Additional hardware may be required depending on the number of spacer connections and the full system configuration.

Assembly Overview

Align the Plate. Install All Four Grade 8 Fasteners.

The spacer installs between compatible plated truss sections using the same four-bolt connection method as a standard EVT12S joint.

01 — Inspect the Plate

Check the plate, bolt holes, surfaces, and hardware for damage or deformation.

02 — Align the End Plates

Position the spacer between the mating plates without forcing alignment.

03 — Install the Hardware

Insert all four Grade 8 bolts with the matching washers and nuts.

04 — Tighten Evenly

Tighten opposite fasteners in sequence to seat the plates evenly.

05 — Verify Alignment

Confirm the connected truss remains straight, square, and fully seated.

06 — Final Inspection

Check every fastener before loading, lifting, or placing the structure into service.

Safety and Engineering

A Spacer Does Not Increase the Truss System’s Load Capacity.

Every spacer adds another bolted connection to the structure. Allowable loads depend on the complete truss configuration, span, supports, connection count, orientation, and project-specific engineering.

Use only undamaged spacer plates and complete Grade 8 hardware sets.

Inspect the plate, bolt holes, mating end plates, bolts, nuts, and washers before every use.

Install all four Grade 8 bolts and tighten them to the required specification.

Do not force misaligned plates together or use the bolts to pull a distorted structure into position.

Do not place concentrated loads directly at the spacer connection unless specifically allowed by the engineering.

Stacked spacer configurations create additional joints and must be reviewed as part of the complete system.

Load-bearing and suspended structures require review by a qualified structural or entertainment-rigging engineer.

Product Questions

Frequently Asked Questions

Why use a 3/8-inch spacer?

It closes a fractional-inch gap when standard truss sections cannot reach the exact required dimension.

Does it use standard EVT12S hardware?

Yes. It uses the standard four-bolt end-plate connection and includes four Grade 8 bolts, nuts, and washers.

Can multiple spacers be stacked?

Yes. It can be combined with other EVT12S spacer sizes, but each added spacer creates another bolted connection that must be included in the system review.

Is it compatible with other brands?

It may fit other standard 12-inch end-plate bolt truss systems, but exact fit is not guaranteed. Verify plate dimensions and bolt-hole spacing first.

Does the spacer increase truss capacity?

No. It changes the overall dimension and adds another connection. Capacity depends on the complete engineered configuration.
