4-Chord Square Aluminum Box Truss – Spigot Quick-Connect Modular Stage Lighting Trussing

The workhorse of professional stage rigging. Our spigot-type 4-chord square aluminum box truss is trusted by event riggers worldwide for its unbeatable combination of speed, strength, and versatility. Built from aviation-grade 6061-T6 aluminum alloy with a polished silver finish, it assembles in minutes without tools and handles the heavy loads of concert roofs, wedding arches, trade show booths, and more — all in a lightweight frame that’s easy to transport between venues.

Why Choose Our Spigot Truss?

⚡ Tool-Free Spigot Quick Connection
Male and female spigot ends are pre-fabricated on every section. Insert and lock with a cotter pin — no bolts, no wrenches, no extra hardware. One person can assemble a full rig in a fraction of the time compared to bolt plate systems, cutting on-site labor costs significantly.

✨ Polished Silver Anti-Oxidation Finish
Bright natural silver aluminum surface resists rust and oxidation without paint — no peeling, no repainting needed. Smooth, burr-free edges protect your lighting clamps, cables, and equipment during every setup and teardown.

🔧 Modular & Fully Customizable
Combine with 6-way cube connectors, multi-angle corners, and mobile base plates to build straight rigs, square roof frames, arched backdrops, and multi-layer structures. Custom lengths from 0.5m to 4m available to suit any venue or event scale.
