Mantus Anchor Swivel

The Strongest Link in Your Chain

The Mantus Swivel is an anchor swivel and shackle in one, designed to keep your chain from twisting and to guide the anchor into the bow roller in the correct orientation. Its integrated shackle design eliminates side loading, and its oblong pin — developed with computer modeling and physical testing — makes the swivel stronger than its corresponding Grade 40 chain. Body: precision-cast, electro-polished 316L stainless. Pin: Duplex stainless steel.

The strongest link – the Mantus anchor swivel is stronger than its corresponding Grade 40 chain. (WLL is 1/5 UBS)

Integrated swivel shackle design completely eliminates side loading, making this the safest anchor swivel on the market.

The pin on the chain side of the swivel is the strength-limiting part since the geometry of the chain determines the pin size. The Mantus anchor swivel and shackle is the first to feature an oblong pin to maximize the pin strength. With the aid of computer modeling and physical testing, we truly created a swivel that is the strongest link.

Note the innovative shackle bolt design – no shackle dog! This slim hex head design (with holes for safety wire) offers a slimmer profile making it easier for translating through your bow roller.

• 316 L Stainless Steel, Precision Cast and Electro-Polished Body
