ALUTRUSS QUADLOCK QL-ET34-4000 4-Point Truss

ALUTRUSS QUADLOCK QL-ET34-4000 4-Point Truss – Maximum Span for Professional Truss Systems

The ALUTRUSS QUADLOCK QL-ET34-4000 is a heavy-duty 4-point truss with a length of 400 cm—ideal for large-scale truss structures in theater, trade show, or event settings. Thanks to its sturdy construction, high-quality aluminum alloy, and proven Quick-Lock system, this component is particularly well-suited for intensive, professional use in touring, permanent installations, and event productions.

Part of the QUADLOCK QL-ET34 truss system

The QL-ET34 system is based on four conical connectors with pins and cotter pins, which guarantee a force- and form-fit connection between the trusses. The Quick-Lock system enables fast, tool-free assembly—perfect for time-sensitive setup and teardown phases on tour or at events.

High-performance materials for maximum load capacity

Manufactured from EN-AW 6082 T6 aluminum (AlMgSi1 T6), this truss combines maximum strength with low weight. The 50 mm diameter truss tubes with a 2 mm wall thickness, as well as the 20 mm thick struts, ensure outstanding load-bearing capacity and torsional rigidity—even across the full 4-meter length.

For large truss frames, stage superstructures, and LED walls

With a length of 400 cm and external dimensions of 29 x 29 cm, the QL-ET34-4000 is ideal for applications requiring the largest possible spans with a minimal number of connection points. The 240 mm hole center-to-center distance is standardized and ensures full system compatibility within the QL-ET34 portfolio.

Polished surface for professional applications

The high-gloss polished surface not only ensures a high-quality appearance but also protects the crossbeam from corrosion and signs of wear—ideal for applications in visible areas, such as at trade shows, on performance stages, or in theaters.

Tested safety—Made in Europe

The truss is manufactured in Europe, welded by SLV-certified welders using the TIG pulse process, and fabricated with AlMg 5 welding material. Production is TÜV Süd certified, and a load chart for structural design is available online—ideal for project planners, technicians, and event service providers.

Note: This truss is intended exclusively for use within the QUADLOCK QL-ET34 system and must not be combined with other systems.

For professional use at the highest level

Whether for stage superstructures, LED frames, large lighting trusses, or complex truss systems—the ALUTRUSS QL-ET34-4000 offers the necessary span, stability, and flexibility to safely execute even the most demanding projects.
