JIS F 2007-1976 Mooring Chock

Introduction:

JIS F 2007-1976 is a Japanese standard for bulwark mounted chock. There are two types of chocks that meet the Japan standard: type A and type B, which are installed on the ship's bulwark. Marine chock can limit the position of the mooring rope when it is working, and can extend the service life of the mooring ropes while protecting the hull.
