Low Friction Rings by All Gear are made of premium aluminum and aircraft quality coating for a smooth glide when running rigging line through the middle. They are used on lowering lines (bull rope), whoopie slings, dead-eye slings, ring to ring slings and 12-strand and double braid composite slings. They can also be used for climbing using false crotch as a friction saver. Benefits: They are easier and faster than a block rigging system, light and easy to handle and provide simple, quick rigging.
