As an HMS, or pear-shaped carabiner, 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" 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.Two important features make the Rock Exotica Screw-lock unique from all others. First, all aluminum parts are anodized. This is particularly important for the screw-sleeve and gate, since without this coating, it is more susceptible to corrosion. This protective surface also gives the sleeve a smoother spin.Second, the gate was designed with an enlarged flange at the top. This prevents the screw-sleeve from moving past the end of the gate, whereas with other designs, the sleeve can wear past the last thread of the gate and slip off.
