ALUTRUSS QUADLOCK TQ390-3000 4-Point Truss

ALUTRUSS QUADLOCK TQ390-3000 4-Point Truss – Heavy-Duty 3-Meter Truss for Professional Large-Scale Structures

The ALUTRUSS QUADLOCK TQ390-3000 is a 3-meter-long 4-point truss from the TQ390 system, which was developed specifically for use in heavy-duty truss structures. With a generous outer dimension of 390 mm and reinforced struts, it is ideal for applications in stage construction, touring, and trade show construction or for permanent installations in clubs, theaters, and large event venues.

Optimized for heavy loads and long spans

Thanks to the 50-mm-diameter tube members with a 2-mm wall thickness and 20-mm-diameter struts, the TQ390-3000 offers an outstanding weight-to-load-capacity ratio. The design is engineered for maximum load-bearing capacity while optimizing weight—perfect for rigging, LED walls, PA setups, or truss roofs.

Quick assembly with the QUICK-LOCK system

Connections are made using the proven QUICK-LOCK system with tapered connectors, pins, and split pins, which enables a force- and form-fit assembly without any tools. This saves you time during setup and teardown—ideal for professional use in everyday touring.

Robust construction with 390 mm outer dimensions

The generous outer dimensions of 39 x 39 cm make the TQ390 series particularly well-suited for large-area, heavy-duty truss systems. It enables better load distribution and increases structural stability—even with wide spans and complex rigs.

TÜV-certified safety

The truss is manufactured in Europe under strict quality standards using the TIG pulse welding process with AlMg 5 welding material. The entire production process is TÜV Süd certified. A load chart for structural design is available online.

Important note:

The TQ390 series cannot be combined with other truss systems. Due to its specific system dimensions and design, it may only be used within the TQ390 system.
