Cargo lashing fitting

A cargo lashing fitting for affixing to a deck of a transportation vessel, said deck including an opening therein, said fitting configured to cooperate with an engagement component of a lashing gear assembly, said fitting comprising:

• a housing sized for insertion within said opening of said deck, said housing being secured to said deck, said housing defining an interior surface and including a plurality of shelves extending radially inwardly from said interior surface, each of said shelves defining an upper shoulder, a lower wall, and a pair of opposing side edges;
• an insert assembly, said insert assembly including:
• a base having a generally circular body defining an upper end, a lower end, and an exterior surface, said base further including an engagement plate located at said upper end, said base further including a plurality of flanges extending radially outwardly from said body near said upper end, said flanges being sized and configured to cooperate with said shoulders of said housing when said base is installed in said housing, each of said flanges defining an upper surface and a lower edge, said base further including a plurality of blocks extending radially outwardly from said body, said blocks being located at said lower end of said base and being sized and configured to cooperate with said lower walls of said shelves when said base is installed in said housing;
• a locking ring having a circular frame, said frame having a plurality of tabs extending downwardly therefrom, each of said tabs defining a lower edge;
• said locking ring being telescopically coupled to said base such that said locking ring can be moved from a first telescoped position wherein said lower edges of said tabs are substantially aligned with said lower edges of said flanges of said base and a second collapsed position wherein at least a portion of said circular frame substantially contacts said upper surfaces of said flanges of said base;
• said insert assembly being sized for insertion into said housing when said locking ring is in the telescoped position, said insert assembly being further sized for rotation within said housing such that said blocks of said base engage said lower walls of said shelves of said housing;
• and
• wherein said tabs of said locking ring are sized for receipt between said shelves of said housing when said insert assembly is rotated within said housing and said locking ring is moved to said collapsed position thereby locking said insert assembly against rotation with respect to said housing.
