ISC Oval Aluminium Carabiner

The ISC Oval Aluminium Carabiner – ISKH411SS1 is a dependable, lightweight connector designed for climbing and rope access applications. Its classic oval shape provides balanced loading, making it especially effective when used with pulleys, hitch systems, and other climbing hardware.

With a minimum breaking strength of 25 kN, this carabiner delivers the strength required for professional use while remaining compact and easy to handle. The rounded basket design helps centre the load evenly through the body, which improves stability and performance. As a result, it works particularly well with both standard and advanced hitch systems, including setups that use a hitch advancing pulley.

Constructed from drop-forged aluminium, the carabiner offers a strong yet lightweight solution for everyday climbing tasks. The anodised finish adds durability and corrosion resistance, while the smooth, tumbled surface reduces wear on ropes and equipment. Each unit is also individually serial numbered and proof tested, ensuring quality and traceability.

The triple-action Supersafe gate enhances security by requiring three deliberate movements to open. This design reduces the risk of accidental opening, even in demanding conditions. At the same time, it allows for one-handed operation once familiar, which is essential for efficient climbing. The inclusion of stainless steel springs improves long-term reliability, while the blind nose design helps prevent snagging on ropes or gear.

In addition, the squared profile around the locking area helps shed dirt and debris, keeping the mechanism functioning smoothly in outdoor environments.
