Description
Description
The Stein SECURA Oval carabiner is a strong and lightweight carabiner in aerospace-grade aluminium with a 3safe locking system. Perfect for professional users who require high safety and reliability.
SECURA OVAL Carabiner: Built for Performance and Safety
The SECURA OVAL carabiner is designed for professional users who require reliability and safety. Made from 7075 aerospace-grade aluminium with a hot-forged body, it delivers an exceptional strength of 30kN while maintaining a low weight of just 83g.

With a large gate opening of 26 mm and a major axis strength of 25kN, the SECURA is designed to handle demanding loads. The anodised finish provides corrosion resistance, improves durability and extends the service life.
Each carabiner is individually serial-numbered for traceability and inspection.
