Steel Carabiners

These carabiners use thick 12mm bar to achieve very high strength ratings. They are suitable for heavy duty rigging operations where strength is paramount. Steel carabiners are very strong and hard wearing, making them suitable for scenarios with high loads and heavy use. Cold forging means carabiners retain full section bars for consistent rope handling, while heat treatment results in high tensile strength.
 
HMS carabiners have extended top bars to accommodate multiple attachments like slings and knots. Their top bars are curved, allowing attachments to self centre and encouraging optimal loading. HMS carabiners tend to be large, for better compatibility with thick ropes and while wearing gloves.
 
The gate opening is the distance between the nose of a carabiner and the gate when it is fully opened. Larger gate openings make a carabiner easier to use while wearing gloves, and with thick ropes and slings. Internal volume refers to the area inside a carabiner, and large internal volumes mean easier attachment and removal of multiple devices, knots and slings.

Features

  • Conforms to EN362:2004/B

  • HMS shape provides large internal volume and gate clearance

  • Smooth internal shape for ease of rotation through attachment eyes

  • 12mm bar section for maximum strength

  • Cold forged and fully heat treated carbon steel for high strength and durability

  • Zinc plated to EN ISO 2081:2008 Fe/Zn 5c standard for corrosion protection

  • Recommended as a belaying carabiner in conjunction with dynamic nylon ropes

  • Individually marked for traceability

  • Screwgate - Non auto-locking gate which requires two actions to open, and is easy to use with one hand. Screwgates are suitable in systems where anchor points can be easily monitored and are unlikely to be affected by running ropes.

  • Locksafe - An auto-locking gate requiring three separate actions to open. Locksafe gates give extra security in complex rigging systems such as those featuring running ropes or remote anchor points.
