HMS carabiners have two main characteristics: they have a very large gate opening and a large rope basket that can accommodate all knots. Pear-shaped carabiners are used in particular for belaying with an Italian hitch and with most belay devices.

How many types of carabiners are there?

There are three main types of carabiner: non-load-bearing (accessory) carabiners, basic or normal carabiners (often referred to as non-locking carabiners) and locking carabiners.

Why are carabiners that shape?

Classic. The first carabiner shape to be mass produced (in the US we thank Chouinard and SMC). When loaded, the pressure is shared equally on both sides of the ‘biner. Since the weaker gate shares the load with the spine, oval biners aren’t as strong as shapes that direct the load to the stronger spine.

Why is it called a carabiner?

The word carabiner entered English some time around 1915, during World War I. The word ultimately has its roots in the German word Karabinerhaken, meaning “carbine hook”—a hook used to connect a soldier’s carbine (a type of rifle) to a strap. In English, the word was shortened to carabiner.

How is a carabiner made?

All carabiners begin their lives as a tube of extruded aluminum alloy called rod stock. The alloy consists of aluminum, which is naturally lightweight and pliable for easy forming, and zinc, which adds strength. Thousands of gateless, rough, gray biners are then heated again to strengthen the alloy in its new shape.

What is a straight gate carabiner?

The straight gate allows an easy clipping on the bolts. The contact surfaces are wider to reduce wear and improve the passage of the rope. The D shape transfers the majority of the load on the main axis of the carabiner, which is the most resistant.
