What types of structures can the EVT12S-7IN Black be used to build?

This spacer integrates into any structure built on 12-inch square plated truss — lighting grids, speaker arrays, trade show booths, scenic frameworks, camera rigs, overhead motor points, and architectural installations. Anywhere the design calls for a short extension between full-length sections, the 7-inch spacer fills that gap whether the layout runs horizontally, vertically, or at an angle.

What hardware is required for installation?

The spacer connects using Grade 8 zinc-plated steel bolts through the end-plate system. Use only the specified bolt grade and torque values. Do not substitute lower-grade hardware, and verify all connections are secure before loading the structure.

Can this spacer be mounted horizontally between two truss sections, or is it only for vertical stacking?

The EVT12S-7IN Black mounts in any orientation — horizontal, vertical, or angled. It uses the same end-plated bolt connection as every other component in the 12-inch square truss line, so it transfers load evenly regardless of how it is positioned. Horizontal runs for LED wall frames, vertical lifts for speaker arrays, and angled bridging for scenic structures all work with the same hardware and installation method.

EVT12S-7IN-Black Truss Spacer

7 Inch Matte Black Truss Spacer.
Adds a 7 Inch Section to 12-Inch End-Plated Truss Systems.

The EVT12S-7IN-Black is a matte black, plated-bolt aluminum spacer for EVT12S and 12-Inch End-Plated Truss Systems. It supplies a 7 inch / 177.8 mm section within a truss run. The finish is matte black powder coat. This component adds length and a bolted connection; it does not increase the capacity of the completed truss system.

Product Overview

A 7 Inch Black Spacer for 12-Inch End-Plated Truss Systems.

The EVT12S-7IN-Black supplies a seven-inch section for EVT12S and 12-Inch End-Plated Truss Systems. Its black powder-coated exterior is suitable when a dark-finish component is required. It is built from EN AW-6061 T6 aluminum alloy with an end-plated bolt connection.

Seven Inch Section

Adds 7 in / 177.8 mm at a compatible end-plate connection.

Matte Black Finish

Factory-applied powder-coat surface.

12 Inch Square Size

Overall dimensions are 12 x 12 x 7 in.

Bolt Connection

Uses an end-plated nut-and-bolt interface.

Application Uses

For Dark-Finish Truss in Staging, Touring, and Display Systems.

The seven-inch black spacer may be considered for compatible lighting grids, scenic structures, trade-show displays, venue systems, touring equipment, and rental inventory where a dark-finish component and seven-inch section are specified. The entire installation, not the spacer alone, must be evaluated for the intended loading and support conditions.

Dark-Finish Systems

A matte black component for compatible dark-finish truss runs.

Lighting Grids

For compatible end-plated truss grid systems.

Scenic Structures

For compatible stage and scenic truss assemblies.

Trade Displays

For compatible exhibit structures that call for a seven-inch section.

Rental Inventory

Provides a seven-inch black-finish option in compatible inventory.

Included Hardware

Hardware Supplied for One Four-Point Connection.

Four Grade 8 bolts, four nuts, and four washers are included with the spacer. Verify the hardware requirements at every actual joint, including bolt length, condition, engagement, and the applicable tightening procedure. Other completed-system joints may require additional hardware.

4 Grade 8 Bolts

Provided for the four-point end-plate connection.

4 Nuts

Included with the supplied bolt set.

4 Washers

Included in the hardware set.

Joint Review

Check each completed-system joint before service.

System Compatibility

EVT12S and 12-Inch End-Plated Truss Systems. Verify Every Connection.

The EVT12S-7IN-Black is designed for EVT12S and 12-Inch End-Plated Truss Systems. Before connecting products from different systems, verify plate dimensions and thickness, bolt-hole positions, chord alignment, hardware requirements, fastener engagement, and complete-joint seating. A shared nominal size alone does not establish connection suitability.

EVT12S

Designed for EVT12S 12-inch end-plated truss components.

End Plates

Compare plate size, thickness, and bolt-hole locations.

Hardware

Confirm the required fasteners and engagement.

Completed Joint

Inspect alignment and full plate seating before use.

Assembly Overview

Align the End Plates. Install and Check All Four Fasteners.

Assembly must be performed by personnel qualified for the truss system and in accordance with applicable manufacturer requirements. This outline does not provide torque values or installation approval.

01 — Inspect

Check tubing, welds, plates, holes, and hardware for damage.

02 — Align

Bring compatible end plates together without forcing distorted parts.

03 — Install Hardware

Fit the specified fasteners at all four locations with adequate engagement.

04 — Tighten

Follow the applicable manufacturer fastener procedure.

05 — Check Seating

Confirm full seating and the required hardware.

06 — Inspect Before Service

Review the completed system and supports before loading.

Safety and Engineering

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

Allowable loading depends on the complete truss system, including span, supports, orientation, joints, suspension method, and applied loads. Suspended, load-bearing, dynamic-load, and complex applications require qualified structural or entertainment-rigging review. No stand-alone load rating or torque value is provided here.

Inspect the spacer, welds, plates, bolt holes, hardware, and connected truss before every use.

Remove any component with cracks, bends, elongated holes, plate deformation, damaged welds, or substantial finish damage from service.

Install and tighten all required fasteners using the applicable manufacturer procedure.

Do not support loads directly from spacer connection points without approval for the complete truss system.

Verify connection interfaces and completed-system suitability before combining products from different systems.

Have a competent person perform a documented inspection at least annually and remove unsafe parts from service.

Truss Spacer Questions

EVT12S-7IN-Black Frequently Asked Questions.

What are 7 inch black truss spacers used for?

They add an exact seven-inch section to a truss run where a dark finish is specified. Typical jobs include scenic structures, lighting grids, touring equipment and trade-show displays, where a run has to land on a pick point and a neighboring spacer length would leave it short or long.

How does the black 7 inch spacer differ from the brushed one?

The only difference is the matte black powder-coat finish. The 12 x 12 x 7 in size, 6061-T6 aluminum, 15.80 lb weight and four-bolt end-plate connection match the brushed 7 inch spacer. The coating does not change what the truss can carry.

Which spacer size should I order for my gap?

Measure the shortfall between the end plates and choose the spacer closest to it without going over. The 7 inch spacer adds 7 in / 177.8 mm, so 7 in plus a 1/2 inch plate adds 7.5 in / 190.5 mm, and 7 in plus a 4 inch spacer adds 11 in / 279.4 mm. Every added piece is another bolted joint and needs its own hardware.

How do I look after the powder-coat finish?

Inspect it before every use, along with the welds, plates and bolt holes. Chips and light wear are cosmetic, but substantial finish damage means the component should be removed from service until it has been assessed, and any cracks, bends or elongated holes are grounds for removal.
