The ISC HMS Supersafe Karabiner (KH204) is a high-performance aluminium karabiner for climbers, arborists, and rope access professionals. It offers a 27kN breaking strength, providing extra confidence in critical climbing systems. Weighing just 93 grams, it combines lightweight performance with exceptional durability, making it ideal for complex rope setups.
The karabiner features a large, rounded basket area, perfect for pulleys under a hitch. The smaller crotch area prevents rotation and reduces side loading, protecting both the karabiner and the rope. It fits climbing lines up to 13mm, giving stability in multi-point systems.
ISC drop-forged the KH204 from high-quality aluminium for maximum strength. They then anodised the surface, giving long-lasting corrosion resistance and a smooth finish. Each karabiner comes with an individual serial number and undergoes a proof check before shipment. The blind nose design reduces snagging or rope damage.
The patented triple lock gate uses stainless steel springs for secure operation. You can operate it one-handed once you master the mechanism. Square corners around the locking pin prevent debris buildup, ensuring smooth performance in challenging environments.
Inspect all karabiners visually and manually before use and after any significant incident. Follow ISC’s cleaning and maintenance guidelines. If the karabiner shows signs of damage or does not function properly, retire it immediately.
The ISC HMS Supersafe 27kN Aluminium Karabiner (KH204) combines strength, safety, and efficiency for professional climbing and arborist applications. Its thoughtful design, durable construction, and secure triple lock gate make it a reliable component of any climbing system.
