Add a 316 stainless steel Wichard anchor chain grip to your custom anchor bridle. The grips optimised design avoids accidental release of the chain and allows for single person deployment and retreival.
 
All anchor grips include a 316 stainless steel bow shackle that is connected to the bridle. The bow shackle pin is then seized with 316 stainless steel wire to ensure that the pin never works loose.
