Spartan Marine's locking chock has been designed to quickly accept an anchor or mooring line and lock it in place. This chock can also be considered for the stern where rising and falling tides can easily cause a dock line to escape from a straight chock.

Solid manganese bronze for a tough cast construction. A strong 5/16 stainless steel bolt easily slides to form a large 1.5" opening between the chock jaws. The wide 1.625" chock base has three mounting holes for 1/4" fasteners.
