SPTE390 hanger: secure attachment for suspended structures
The SPTE390 hanger is an aluminum lifting element designed for the secure suspension of QUATRO39 structures (390×390 mm). Equipped with a sling eye and two Ø50mm tube clamps, it allows QUATRO39 beams to be attached to overhead anchorage points: lifting grids, lifting motors, supporting beams or existing structures. Manufactured from high-strength aluminum, the SPTE390 supports a maximum load of 500 kg, ensuring optimum distribution of forces on the beam. Its black finish ensures perfect visual discretion for stage and event installations. Dimensions: 402 x 50 x 198 mm (L x W x H), weight: 4.43 kg.

Certified European manufacture
Every SPTE390 suspension component is made in Europe from high-strength aluminum to ISO DIN 4113 and TÜV standards. This certification guarantees maximum reliability and safety for your permanent or temporary suspended installations. The quality of the materials used and the rigorous quality control applied to each component ensure long-lasting performance and optimum resistance to the mechanical stresses of lifting structures. The SPTE390 meets the requirements of professional service providers, installers and design offices looking for reliable solutions for critical suspension systems.

Double clamp system
The SPTE390 uses a double clamp system for Ø50mm tubes, ensuring a solid, balanced grip on QUATRO39 beams. This system ensures even load distribution on the beam, while facilitating precise positioning of the suspension point. Theattachment eye allows direct connection of certified slings for secure lifting. Ideal for event organizers, the SPTE390 is quick to install and ensures impeccable stability of suspended structures.

Compatible with QUATRO39 range and Contestage accessories
The SPTE390 hanger is specifically designed for the QUATRO39 series with its Ø50mm main tubes. Compatible with all Contestage slings and lifting accessories, it integrates easily into your existing installations. Maximum load: 500 kg. To ensure the safety of your installations, always respect the maximum loads indicated and use certified slings.

QUATRO39 is a range of 390 x 390 mm square aluminum structures designed for stage, event and architectural installations requiring high span and maximum strength. Manufactured in EN AW-6082 T6 aluminum with Ø50x3mm main tubes and 25x2mm reinforcing bars, it offers an excellent strength-to-weight ratio thanks to its optimized spatial design.
The QUATRO39 series is suitable for a wide range of configurations: stage roofs, exhibition structures, LED screen and projection supports, light and sound gantries, advertising frames and stage sets. Its black finish provides perfect visual discretion for professional applications. Available in standard lengths from 0.25m to 3m, complete with 2- to 4-direction angles, 6-direction junction cubes and fixing accessories, the QUATRO39 range makes it possible to create complex structures with a high degree of modularity.

Certifications and performance: guaranteed safety
Every component in the QUATRO39 range is manufactured in Europe to the highest industry standards. ISO DIN 4113 and TÜV certified, the structure guarantees maximum reliability and safety for your permanent or temporary installations. Please refer to our load table for QUATRO39 span capacities according to the distance between supports (up to 22 meters).
For example, over a span of 8 meters, the structure supports up to 295 kg/m in distributed load and 1181 kg in centered load. This exceptional performance is made possible by the quality of the materials used (high-strength EN AW-6082 T6 aluminum) and the rigorous quality control applied to every component. QUATRO39 meets the requirements of professional service providers, installers and design offices looking for reliable structures for critical applications.

Full compatibility with Contestage accessories
Thanks to its standard 50 mm tubes, the QUATRO39 range is compatible with most Contestage fastening and safety accessories, including structural hooks, connecting clamps and slings. This compatibility makes it easy to integrate the QUATRO39 into your existing installations, or to add to your stock of accessories without multiplying the number of part numbers.

Sleeves, keys and pins included
To simplify your projects, every QUATRO39 beam and corner is supplied complete with sleeves, keys and pins. The number of fasteners corresponds exactly to the needs of the element: 4 for beams and angles in 2 directions, 8 for angles in 3 directions, 12 for angles in 4 directions. Ready to assemble on delivery.
