A carabiner or karabiner is a specialized type of shackle, a metal loop with a spring-loaded gate used to quickly and reversibly connect components, most notably in safety-critical systems.
Carabiners are widely used in rope-intensive activities such as climbing, fall arrest systems, arboriculture, caving, sailing, hot air ballooning, rope rescue, construction, industrial rope work, window cleaning, whitewater rescue, and acrobatics.
Use the 4mm Caribina Hooks for things such as:
- Clip keys inside backpacks to loops for extra security.
- Hold two sets of keys that are often detached.
- Clip your flashlight to your pack.
