Carabiners

A carabiner or karabiner (colloquially: crab, D ring, krab, or 'biner) is a metal loop with a sprung or screwed gate. The loop part opposite the gate is referred to as the spine. It can quickly and reversibly connect components in safety-critical systems. The word comes from "Karabinerhaken", meaning "hook for a carbine" in German.

Carabiners are widely used in sports requiring ropework, such as climbing, slacklining, caving ("Single Rope Technique"), canyoning, and sailing.

Carabiners used in sports tend to be lighter than carabiners used in industry. For recreational climbing, almost all carabiners are made from 7075 aluminum and are treated to a T6 temper (solution treated and then artificially aged).

When sold for use in climbing in Europe, carabiners must conform to standard EN 12275:1998 "Mountaineering equipment - Connectors - Safety requirements and test methods," which governs testing protocols, rated strengths, and markings. A strength of around 20 kN with the gate shut is considered a standard strength for most climbing applications, although requirements vary depending on the activity. Carabiners are also marked on the side with single letters showing their intended area of use, for example, K (via ferrata), B (base), and H (for belaying with an Italian or Munter hitch).

All our Carabiners carry the appropriate EN and UIAA Certification.
