Climbing Carabiners and Snap Hooks

Climbing carabiners are used in everyday work situations by arborists. Carabiners vary in their uses from rigging, life support, and even just for carrying accessories. Many carabiners include a locking function to keep the gate from accidentally opening during a climb. These are referred to as auto-locking carabiners. Some even have 2 locks, or “double locking.”

Carabiners are not snap hooks--there is a difference. Carabiners open away from the loop while snap hooks open by pushing in toward the loop. Certain carabiners tend to have wider gate openings than snaps and are less bulky.

Using Carabiners for Life Support

Any carabiner used for life support must be auto-locking, have at least two consecutive, deliberate actions to prepare the gate for opening per ANSI Z133. They must have a minimum tensile strength of 5,000 pounds (22.24kN). Aluminum carabiners are a good choice for life support being that they are lighter in weight than a steel carabiner, just like the DMM Ultra O Lock safe as an example.

Using Carabiners for Rigging

Carabiners used for light rigging do not have to be double locking, but for some applications, double locking would be the safer option. Steel carabiners are ideal for rigging as they won’t warp or fail as quickly as an aluminum carabiner may. A good example is the very popular ISC Steel Oval Screwgate Carabiner.

Using Carabiners to Carry Climbing Accessories

Non-locking carabiners are used as accessory clips for attaching ropes, rigging gear, or saws to a climbing harness. Some are made of plastic and others are made of aluminum. A good choice for carrying accessories would be the Petzl Spirit Carabiner.
