Mantus' stainless steel anchor swivel has a hex-head shackle-bolt design that eliminates side loading and easily moves through bow rollers. The 316L stainless construction provides an incredible amount of strength and reliability.The electro-polished, precision-cast swivel construction is stronger than grade 40 (G40) chain and its WLL is 1/5 UBS. The innovative shackle bolt design means there's no more shackle! The slim, hex-head design offers a slimmer profile that is far more maneuverable than other swivel units.Typically, the limiting factor in a shackle is the pin. Since the geometry of the chain determines the pin's size, a swivel's integrity can be compromised under the twisting forces of anchor retrieval.
Mantus' swivel is equipped with an oblong pin that has greater strength under extreme physical load. The pin has been engineered to be as strong as the rest of the swivel so the weakest part of the shackle is no longer the pin.
