ISC HMS Karabiner KH204

The ISC HMS Karabiner KH204 is a large, high-strength aluminium connector designed for professional arborists, rope access technicians and rigging work. As the largest HMS karabiner in the ISC aluminium range, it provides generous internal volume and smooth handling for multiple rope configurations, belay systems and rigging setups.

With an impressive 27 kN minimum breaking strength and a lightweight anodised construction, the KH204 delivers the ideal balance of strength, durability and ease of use. A wide 22 mm gate opening allows efficient clipping, while the HMS shape supports smooth rope management during complex operations.

Available in four gate options—Screwgate, Twistlock, Supersafe and Quadlock—the KH204 offers versatile compatibility across climbing, lowering and rigging applications. Each karabiner is individually serial-numbered for traceability and manufactured to EN 362 standards for professional use.
