The Strongest Link in Your Chain

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 to translate through your bow roller.

    *Grade 40/70 chain types claim inflated working load limit values. Typically, chains working load limit is calculated as 1/4th of the ultimate breaking strength. Published WLL for Grade 70 /Grade 40 chain are calculated using the safety factor of 3, or UBS/3 = WLL. (G4 HT) is only 50% stronger than G30 chain and Grade 70 chain is only 20% stronger than G40 chain and 85% stronger than G30 chain. Thus, WLL values we use to size you with the correct swivel are WLL = UBS/4 regardless of the chain type. For Mantus Swivels, we use a safety factor of 5 when determining the WLL recommendations.
