Why does the spacer lineup include a 7-inch option when most truss sections come in even-inch or foot increments?

Real-world venue dimensions rarely land on round numbers. A 7-inch spacer lets you hit the exact span length dictated by a room width, column spacing, or scenic ground plan without stacking multiple smaller spacers or leaving an unfilled gap at the end of a run.

Can I combine the EVT12S-7IN with other spacer lengths to build a custom total extension?

Yes. Spacers bolt end-to-end just like full truss sections. Combining a 7-inch with a 5-inch spacer gives you exactly 12 inches, or pairing it with a 4-inch spacer yields 11 inches — letting you assemble virtually any fractional dimension from the spacer inventory without cutting or modifying anything.

Can the EVT12S-7IN be installed vertically to adjust the height between stacked truss layers?

Yes. The spacer works in any orientation — horizontal to extend a run or vertical to raise one layer above another. Vertical installation is common when riggers need to increase the gap between a mother grid and a lighting pipe by exactly 7 inches to clear a scenic piece or hit a specific trim height.

EVT12S-7IN

EVT12S-7IN Truss Spacer

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

The EVT12S-7IN is a plated-bolt aluminum truss spacer for EVT12S and 12-Inch End-Plated Truss Systems. It adds a 7 inch / 177.8 mm section where that length is needed within a truss system. This component adds length and a bolted connection; it does not increase the capacity of the completed truss system.

Product Overview

A 7 Inch Truss Spacer for Length Adjustments.

The EVT12S-7IN supplies a seven-inch section for EVT12S and 12-Inch End-Plated Truss Systems. Its odd-inch length is an option when the required truss run calls for seven inches rather than a neighboring spacer length. The brushed aluminum finish matches the silver EVT12S system format.

7 Inch Section

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

12 Inch Square Size

Overall dimensions: 12 x 12 x 7 in / 304.8 x 304.8 x 177.8 mm.

Brushed Aluminum

A surface finish for silver truss systems.

Bolt Connection

Uses end-plated nut-and-bolt hardware.

Application Uses

For Touring, Staging, Rental, and Custom Truss Systems.

The seven-inch component may be considered for compatible touring structures, lighting grids, trade-show displays, rental inventory, and venue truss systems where that section length is specified. The required supports, span, and loads must be evaluated for the full installation rather than inferred from the spacer length.

Venue Truss

For compatible systems with fixed support locations.

Trade Shows

For compatible booth and display truss structures.

Lighting Grids

For compatible end-plated grid systems.

Touring Systems

An odd-inch section option within compatible touring inventory.

Rental Inventory

Provides a seven-inch length in compatible spacer stock.

Included Hardware

Supplied with Hardware for One Four-Point Connection.

Four Grade 8 bolts, four nuts, and four washers are included with the spacer. Confirm the fastener requirements at every actual joint, including bolt length, condition, engagement, and the manufacturer tightening procedure. Additional hardware may be needed for other joints in the completed truss system.

4 Grade 8 Bolts

Provided for the four-point end-plate connection.

4 Nuts

Included with the supplied bolts.

4 Washers

Included in the hardware set.

Connection Count

Account for the hardware needed at each joint in the full system.

System Compatibility

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

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

EVT12S

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

End Plates

Compare plate dimensions and bolt-hole positions.

Hardware

Confirm the appropriate fasteners and engagement.

Completed Joint

Inspect alignment and full seating before use.

Assembly Overview

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

Assembly should be performed by personnel qualified for the truss system in accordance with applicable manufacturer requirements. This outline provides neither torque values nor 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 the required hardware and full plate seating.

06 — Inspect Before Service

Review the completed truss 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, or damaged welds 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 different systems.

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

Truss Spacer Questions

EVT12S-7IN Frequently Asked Questions.

What are 7 inch truss spacers used for?

They add an exact seven-inch section to a truss run when a neighboring spacer length would leave you short or long. Typical jobs include venue truss with fixed support locations, trade-show structures, lighting grids and touring rigs, where a run has to land on a pick point.

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.

Does a 7 inch truss spacer increase the load capacity of my truss?

No. It adds length and one more bolted connection. The loading the completed system can carry depends on its span, supports, orientation, joints and suspension method, so follow the ratings of your main truss sections. Do not support loads directly from the spacer connection points without approval for the complete truss system.

How heavy is the 7 inch spacer, and what is it made of?

It weighs 15.80 lb / 7.16 kg and is built from EN AW-6061 T6 aluminum with 50 mm main tubing and 25 mm brace tubing, in a brushed finish. It is TÜV certified and carries a 1-Year Limited Manufacturing-Defect Warranty. Plan a safe lift when you place it overhead.
