System Overview

A Modular Overhead Framework Built to Keep Floor Space Open.

The SkyGrid-400 forms a rigid square perimeter using straight EVT290S truss sections, corner junctions, and secure connection hardware.

Suspended 20x20 Layout
Creates an overhead perimeter for fixtures, signage, scenic elements, and production equipment.
Modular Construction
Uses standard EVT290S components that can be expanded or reconfigured for future installations.
Conical Connection System
Couplers, tapered pins, R-clips, and M12 hardware at applicable junctions create secure repeatable connections.
Ground Assembly
The complete grid is assembled and inspected at floor level before being lifted into position.

Common Applications

Designed for EVT290S, F34, and Standard 290 mm Square Truss Systems.

System Compatibility

EVT290S, F34, and Standard 290 mm Square Truss Systems.

The SkyGrid-400 uses 290 mm square truss geometry, 50 mm main chords, and a matching conical connection system. Compatibility requires matching receiver spacing, coupler dimensions, connection geometry, and engineering data.

EVT290S Compatibility
Integrates with compatible EVT290S straight sections, corners, junctions, and expansion components.
F34 Compatibility
Compatible with matching F34 290 mm square truss geometry and conical hardware.
Standard 290 mm Square Systems
Verify receiver spacing, connection geometry, and engineering data before combining systems.
50 mm Clamp Compatibility
Main chords accept properly rated standard 50 mm / 2 in clamps.

Assembly Overview

Assemble on the Ground. Inspect Before Every Lift.

Assembly, suspension, lifting, leveling, and final positioning must be completed by qualified riggers using rated lifting equipment and following the approved rigging plan, engineering requirements, and venue rules.

01 — Lay Out Components
Arrange the straight truss sections, corners, and connection hardware in the final square configuration.
02 — Inspect Every Part
Check truss, junctions, couplers, pins, R-clips, and bolts for damage, wear, or deformation.
03 — Connect the Grid
Install conical couplers, tapered pins, R-clips, and applicable junction bolts.
04 — Verify Geometry
Confirm the grid is square, all connections are seated, and every fastener is properly secured.
05 — Attach Suspension Hardware
Install the approved span sets, shackles, motors, or chain falls according to the engineered rigging plan.
06 — Lift as a Complete Assembly
Raise the grid evenly, monitor all lifting points, and stop immediately if the grid racks, twists, or lifts unevenly.

Safety & Engineering

Overhead Loads Require Project-Specific Engineering.

The allowable load depends on suspension-point quantity and location, truss orientation, support conditions, attached equipment, load distribution, lifting method, and the rated capacity of the venue structure.

A qualified engineer must determine the allowable distributed and point loads for the specific rigging plan.
Verify the building structure, rigging points, motors, shackles, span sets, and all suspension hardware are rated for the complete load.
Inspect every truss section, junction, coupler, pin, clip, and bolt before each lift.
Do not use any component showing cracks, bends, deformation, severe wear, or damaged welds.
Assemble the complete grid at ground level before lifting.
Use independently rated secondary safeties for overhead fixtures and accessories where required.
Overhead installation and lifting must be performed only by qualified rigging professionals.
Every SkyGrid installation requires qualified riggers and rated motors, chain falls, or other approved lifting equipment.

System Questions

Frequently Asked Questions

Does the SkyGrid-400 include suspension hardware?

No. The system includes the truss sections, corners, and connection hardware. Span sets, shackles, motors, chain falls, rigging points, and related suspension equipment are site-specific and purchased separately.

How is the grid assembled?

The grid is assembled at ground level by connecting the four perimeter sides and corner junctions. All connections must be inspected before the complete grid is lifted into position.

What is the load capacity?

There is no universal load value for every installation. Capacity depends on the suspension plan, number and location of pick points, attached loads, and venue structure. A structural engineer must determine the allowable load.

Can the grid size be expanded?

Yes. Compatible EVT290S straight sections and junction components can be used to create alternate dimensions. The revised system must be evaluated before use.

What inspections are required?

Every component and connection must be visually inspected before each lift. Documented periodic inspections should also be performed by a competent person according to applicable requirements.
