Description
The ISC HMS Super Safe Aluminium Carabiner KH204SSQ (Triple, 27kN) delivers high security, smooth handling, and professional-grade strength for arborist and rope access systems. It is designed for users who need a reliable locking connector for demanding climbing and rigging work.
First, the carabiner uses a large HMS shape. This design improves rope management and keeps loads aligned along the major axis. As a result, it reduces cross-loading and improves performance in belay systems, anchors, and rigging setups.
Next, the aluminium body keeps weight low while maintaining strength. It achieves a 27 kN minimum breaking strength, giving it a strong safety margin for professional use. Therefore, it performs well in both climbing and industrial work-at-height environments.
The Supersafe triple-lock gate system adds a high level of protection. It requires three separate actions to open. This significantly reduces the risk of accidental gate release. In addition, it supports fast but controlled operation once you become familiar with the mechanism.
Furthermore, the snag-resistant keylock nose prevents catching on ropes, slings, and bolts. This improves efficiency during clipping and unclipping, especially in tight or complex rigging systems.
The carabiner is also CE EN362 certified, confirming compliance with industrial safety standards. At approximately 98–100 g, it stays lightweight enough for daily climbing use without sacrificing durability.
Although compact compared to some HMS models, the ISC HMS Super Safe Aluminium Carabiner still provides generous internal space for devices such as belay plates and rigging hardware. Therefore, it balances size, safety, and usability in one connector.
Overall, the ISC KH204SSQ Super Safe carabiner delivers strong performance, secure locking, and smooth handling for professional climbing and arborist operations.
