A Clean 90-Degree Connection.
Built for 12-Inch Plated Truss.

The EVT12S-Grapple is a specialized 90-degree connecting bar set for 12 x 12 inch end-plated aluminum truss systems. It allows two straight truss sections to be bolted together at a fixed right angle, creating a clean, flush corner without the visual bulk of a large corner block.

Product Overview

Create a Flush Right Angle Without a Large Corner Block.

The EVT12S-Grapple bolts directly to compatible truss end plates and creates a fixed 90-degree connection between two straight sections.

01 — Inspect the Bars
Check for bending, cracks, deformation, damaged holes, or surface damage.
02 — Verify Compatibility
Confirm the end-plate dimensions and bolt pattern match the grapple set.
03 — Align the Truss Sections
Position both straight sections at a true 90-degree angle without forcing alignment.
04 — Install All Hardware
Use every fastener required by the design and install the nuts and washers correctly.
05 — Tighten to Specification
Tighten the connection evenly to the specified torque.
06 — Final Inspection
Confirm the corner is square, the chords align, and all hardware is secure.

Common Applications

Designed for Clean Perpendicular Truss Layouts.

Best suited for structures where a flush 90-degree corner is preferred over the visual bulk of a large multi-way corner block.

01
Flat Display Frames
Create clean rectangular frames for graphics, signs, scenic panels, and branded displays.
02
Step-and-Repeat Structures
Build low-profile right-angle corners for media walls and photo backdrops.
03
Lighting Grids
Connect perpendicular straight sections in engineered overhead or ground-supported grids.
04
Architectural Perimeters
Create clean border frames and temporary structural outlines.
05
Alignment Correction
Help maintain square geometry at a fixed right-angle junction.

Product Features

A Compact Alternative to a Large Corner Block.

The EVT12S-Grapple is designed around standard 12-inch plated-truss geometry and provides a clean way to create or reinforce a 90-degree junction.

Fixed 90-Degree Connection
Forms a rigid perpendicular junction between compatible plated truss sections.
Low-Profile Appearance
Reduces the visual bulk associated with a large multi-way corner block.
End-Plate Bolt Connection
Attaches directly to compatible four-bolt truss end plates.
Connection Reinforcement
Helps stabilize perpendicular layouts and maintain intended grid geometry.
Connecting Hardware Included
Supplied with the hardware required for the intended connection.
Brushed Aluminum Finish
Coordinates with the standard aluminum finish of EVT12S truss.

Safety and Engineering

This Connection Behaves Differently from a Standard Corner Block.

The grapple creates a moment connection between two plated truss sections. Load-bearing applications require review by a qualified structural engineer.

Do not apply loads to the grapple connection unless the complete configuration has been engineered for that use.
Inspect the grapple bars, bolt holes, fasteners, mating end plates, and truss chords before every use.
Do not use components with cracks, bends, deformed plates, elongated holes, damaged welds, or severe wear.
Install all four Grade 8 bolts and tighten them to the required specification.
Do not mix truss brands unless plate geometry, chord alignment, and engineering data have been verified.
A competent person should perform a documented inspection at least annually.
A licensed professional engineer must review the complete structure where required.

Product Questions

Frequently Asked Questions

What does the EVT12S-Grapple do?

It creates or reinforces a fixed 90-degree connection between two compatible straight plated truss sections.

Why use this instead of a corner block?

It provides a cleaner, lower-profile corner for flat frames, signage borders, and similar display structures.

Is connecting hardware included?

Yes. The product source lists connecting hardware as included.

Will it fit other plated truss brands?

The set is machined for EVT12S specifications. Verify the end-plate dimensions, bolt pattern, and chord alignment before using it with another system.

Can it be used for load-bearing structures?

Only after the complete configuration and connection have been reviewed by a qualified structural engineer.
