The Ultra Marine swivel connects the anchor and chain without the need for additional hooks. It is made from 316 stainless steel and hand-polished for an amazing appearance, very strong and slim, and does not require securing pins or safety wires. Features: -One-piece construction: The molded (not cast) body ensures maximum strength. -Semi-spherical head: Self-adjusting, allows 360-degree rotation. -Hex head bolts: Maximum security to prevent accidental release. -TEFLON O-ring: The internal O-ring made from TEFLON absorbs friction, providing low resistance and smooth operation. Combined with the 360° rotation capability, the setting and retrieval of the anchor are now easier and safer.
