Arborist-specific: The Pirate easily accommodates the use of a wide range of gear, webbing or ropes - either as a belay biner at the harness, or as a connector in a system. The Pirate's robust 0.5 in diameter round frame will endure abuse from dirty ropes and metal connectors far beyond stamped carabiners with thin edges. The Pirate's durability matched with Rock Exotica's build quality ensures an impressive service life for the working professional or recreational enthusiast.
