Stein Secura D 3 Way Carabiner - Green

Stein Secura D 3 Way Carabiner – Green

The Stein Secura D 3 Way Carabiner – Green is built for arborists and professional climbers who need dependable strength, controlled handling, and confidence in every connection. Designed around a D-shape profile, this carabiner is particularly well suited to use with lanyards and slings, where predictable load direction and efficient force management matter. The Stein Secura D 3 Way Carabiner – Green offers a lightweight feel in the hand, which supports smooth movement and reduced fatigue during long working days.

D-shape design for focused loading

The D-shape geometry helps keep loads aligned along the major axis, supporting stable and efficient load transfer when used with slings or positioning lanyards. As a result, the carabiner performs consistently in demanding setups, while also encouraging tidy, organised systems. This focused load path supports confidence when repositioning or adjusting equipment at height.

Triple-action locking for added control

This carabiner uses a Triple Action 3safe locking system that requires three deliberate movements to open. Therefore, the chance of accidental gate opening is reduced during active use. In addition, the KeyLock nose design supports smooth clipping and unclipping without catching on rope fibres, webbing, or hardware, which helps maintain an efficient workflow.

Strong, lightweight construction for daily professional use

Manufactured from hot forged 7075 aviation-grade aluminium, the Stein Secura D 3 Way Carabiner – Green delivers a strong yet compact connection point. With a major axis strength of 30 kN and a 22 mm gate opening, it balances durability with practical handling. The anodised green finish improves resistance to wear and corrosion, while individual serial numbering supports clear inspection records and traceability, which is essential for professional equipment management.
