Manufactured from 316 L Stainless Steel, precision cast and electro-polished body, the strongest link in your chain.
No weak link – Mantus swivel is stronger than the corresponding Grade 40 chain.
Integrated shackle design completely eliminates side loading making this the safest swivel on the market.
The weakest part of any anchor connector is generally the pin that fits onto the chain because the diameter is limited by the inside dimensions of the link.
Mantus swivel features an oblong shaped pin to fit the space available in a chain link and therefore maximise the strength of the pin.
Mantus believe that they have designed and created the strongest link available with the aid of computer modelling and extensive physical testing.
Mantus Swivel has an innovative slim line hex head shackle bolt design with holes for seizing wire.
Mantus Swivel does not require a shackle Key (shackle dog).
The slimmer profile offers a snag free transition over the bow roller
