JIS F 2005-1975 Closed Chock

Introduction:

JIS F 2005-1975 is a Japanese standard for marine chocks. In order to protect the marine chocks, the surface of the cast steel marine chock can be galvanized, polished and painted. Marine chocks can reduce the wear between the mooring ropes and the hull, and can extend the service life of the mooring ropes.
