Define an Overhead Zone
With a 20-Foot Triangular Truss Perimeter.

The SkyGrid-TRI400 is a suspended triangular perimeter frame built from EVT290S 290 mm square aluminum truss. The overall frame shape is triangular; “square” describes the truss profile, not the plan geometry. Its nominal 20 × 20 ft / 6 × 6 m envelope creates an overhead perimeter for planned lighting, AV, signage, scenic, display, studio, and technical installations. The completed structure must be assembled, suspended, and loaded only under a project-specific rigging and engineering plan.

What It Is

A Three-Sided Overhead Frame Built from Square-Profile EVT290S Truss.

SkyGrid-TRI400 is a triangular perimeter structure made from straight EVT290S square-profile truss sections, triangular-corner or junction components, and conical connection hardware. The frame’s three sides define the overhead shape; the 290 mm square profile describes the cross-section of each truss member.

Triangular Plan Geometry
The overall structure is a triangle with three perimeter sides and three corner or junction locations. It is not a four-sided square grid.
290 mm Square Truss Profile
Each perimeter member uses the EVT290S 290 mm square aluminum truss profile.
Overhead Perimeter Function
The frame establishes a triangular overhead zone for planned equipment, lighting, signage, scenic, or display layouts.
Not a Universal Hanging System
The truss frame does not include site-specific suspension hardware or establish an allowable load for every rigging configuration.

Geometry Matters

The Shape Changes the Design Question. Plan a Triangle as a Triangle.

A triangular frame creates different perimeter lengths, corner conditions, equipment positions, and suspension considerations than a square grid. Use the technical drawing and approved project geometry to determine exact side lengths, corner components, pick-point locations, fixture positions, and clearances. Do not infer these values from a nominal 20 × 20 ft description alone.

Three Corners, Not Four
Plan the support, equipment, and cable approach around three structural corners and the actual triangular perimeter.
Nominal Envelope
The product source identifies a nominal 20 × 20 ft / 6 × 6 m envelope; use the drawing for exact layout dimensions.
Reported Inside Dimension
The supplied source reports a 16.39 ft / 5.0 m inside dimension. Verify how this dimension applies to the actual triangular layout before design or installation.
Load Planning Is Geometry-Specific
Pick-point locations, load distribution, truss orientation, and attached equipment must be analyzed for the actual triangle—not borrowed from a rectangular or square grid plan.

When to Select It

Choose It When the Project Needs A Triangular Overhead Zone, Not a Rectangular Grid.

Select SkyGrid-TRI400 when a triangular footprint supports the approved production, exhibit, studio, architectural, or technical layout. The system is appropriate only where the venue structure, rigging plan, suspension equipment, installed loads, and qualified review support the completed overhead configuration.

Triangular Lighting Zones
For lighting layouts organized around a three-sided overhead perimeter where fixture positions are developed in the approved plan.
Angular Exhibit and Scenic Designs
For display, signage, scenic, and branded environments that call for a triangular overhead shape.
Studio and Technical Environments
For controlled spaces where a triangular frame supports a documented camera, lighting, audio, or sensor layout.
Venue-Specific Overhead Systems
For projects where qualified personnel have confirmed the available support structure, rigging points, and lift plan.

System Compatibility

EVT290S, F34, and Matching 290 mm Square-Profile Conical Truss Systems.

The SkyGrid-TRI400 uses 290 mm square-profile truss geometry, 50 mm main chords, and a conical connection system. Compatibility with other components requires matching receiver spacing, coupler dimensions, chord geometry, corner or junction geometry, and engineering data for the revised complete structure. “Square-profile” refers to the truss cross-section; it does not change the triangular frame shape.

EVT290S Compatibility
Integrates with compatible EVT290S straight sections, corners, junctions, and expansion components when the complete configuration is reviewed.
F34 Compatibility
Compatible with matching F34 290 mm square-profile geometry and conical hardware when physical interfaces and engineering data match.
Standard 290 mm Square Systems
Do not rely on the 290 mm classification alone. Verify receiver spacing, connection geometry, corner interfaces, and engineering data before combining systems.
50 mm Clamp Interface
The 50 mm main chords may accept compatible professional truss clamps where placement, load, orientation, and the complete rigging plan are approved.

Assembly and Lifting

Assemble the Triangle at Ground Level. Inspect the Complete Frame Before Every Lift.

Ground assembly must be completed by qualified truss technicians. Suspension, lifting, leveling, and final positioning require a qualified rigging crew, rated lifting equipment, and an approved rigging plan. The following steps describe the required planning sequence; use the current technical drawing and project documentation for exact component orientation and connections.

01 — Confirm the Triangle Layout
Lay out the straight sections and the three corner or junction components in the actual triangular configuration shown by the approved drawing.
02 — Inspect Every Component
Check truss, corners, junctions, all 36 couplers, 72 pins, 72 R-clips, and applicable M12 hardware for damage, wear, cracks, deformation, or incomplete hardware.
03 — Connect the Three Sides
Install the conical couplers, tapered pins, R-clips, and applicable junction bolts according to the approved assembly drawing.
04 — Verify Triangle Geometry
Confirm the triangular perimeter, corner orientation, connection seating, and all fasteners before attaching suspension hardware.
05 — Install Approved Suspension Hardware
Install site-specific span sets, shackles, motors, chain falls, or other rated lifting equipment only under the approved rigging plan.
06 — Lift Evenly and Monitor
A qualified rigging crew must raise the complete frame according to the plan, monitor each pick point, and stop if the frame racks, twists, or lifts unevenly.

Safety and Engineering

There Is No Universal Hanging Load for This System. Allowable Load Is Project-Specific.

The supplied product information does not establish one allowable load for every SkyGrid-TRI400 installation. Capacity depends on the triangular geometry, suspension-point quantity and location, truss orientation, support conditions, attached equipment, load distribution, lifting method, venue structure, and every component in the load path. A qualified engineer must determine the allowable distributed and point loads for the actual rigging plan.

A qualified engineer must determine allowable distributed and point loads for the specific triangular frame, support arrangement, and rigging plan.
Verify the building structure, rigging points, motors, shackles, span sets, and all suspension hardware are rated for the complete installed load.
Inspect every truss section, triangular corner or junction component, all installed couplers, pins, R-clips, and bolts before each lift.
Do not use components showing cracks, bends, deformation, severe wear, damaged welds, or incomplete connection hardware.
Assemble and inspect the complete triangular frame at ground level before lifting.
Use independently rated secondary safeties for overhead fixtures and accessories where required by the approved plan and applicable rules.
Do not use a square-grid load table, a straight-span assumption, or a different geometric system as the engineering basis for this triangular frame.
Overhead installation and lifting must be performed only by qualified rigging professionals.

System Questions

Frequently Asked Questions

Is SkyGrid-TRI400 a triangular system or a square grid?

It is a triangular perimeter system. The EVT290S truss members have a 290 mm square profile, but the overall frame geometry is triangular with three sides and three corners.

How much conical connection hardware is included?

Nine hardware sets are included. Each set contains four couplers, eight coupler pins, and eight R-clips, for totals of 36 couplers, 72 pins, and 72 R-clips.

Does the system include suspension hardware?

No. Span sets, shackles, motors, chain falls, rigging points, and related suspension hardware are site-specific and separate from the frame package.

What is the system load capacity?

There is no universal allowable load for every installation. A qualified engineer must determine allowable distributed and point loads for the actual triangular geometry, pick points, support structure, hardware, and attached equipment.

Can compatible EVT290S components expand or alter the frame?

Compatible components may support an alternate configuration, but any revised geometry, components, suspension plan, and load arrangement must be evaluated before use.

What inspections are required?

Inspect every truss section, corner or junction, coupler, pin, R-clip, bolt, and suspension component before each lift. Perform documented periodic inspections by a competent person as required by the governing conditions.
