Product information & specifications

LOCKI and SIGYN accessory mini-carabiners are more than simple accessories. Specifically designed to meet our expectations, they combine safety, performance and efficiency. Their large opening and practical conception simplify your everyday field work.

The LOCKI differs with its innovative and unique locking system: a quarter turn, to lock or unlock it! This offers an efficient protection against accidental openings. The ergonomic design provides a smooth manipulation, even with gloves, to work faster and more efficiently. You will like the large opening and the carabiner will accompany you on every work site.

The SIGYN has a simple gate, which allows for a quick and effortless use, easing frequent connections/de-connections during everyday tasks.

Designed for intensive use, our accessory mini-carabiners are easily manipulated with only one hand. Their asymmetry, their optimised size and large opening ensure a smooth, instinctive use in many situations, whether to connect your chest harness to your foot loop, to fasten tools on your harness or to assemble throw bags. Manufactured with high quality materials, the carabiners resist to shocks and wear, allowing for a great longevity that will be useful in all conditions. Holding loads up to 5 kN, they combine strength and lightness, for reliable and practical accessories on work sites.
