Claims28
A chain link, said chain link comprising:
- a unitary metal bar having a top, a first end, a second end, a tang space, and a center point;
- said chain link first end being a clevis, said clevis having a through opening through the prongs of said clevis of predetermined size;
- said tang opening having a back wall, said back wall being beveled and having an insert opening therein;
- said chain link second end having a centered prong, said centered prong having a predetermined second through opening therein, said centered prong being configured to fit a clevis first end on an adjoining chain link;
- said chain link second end having an integrally mounted prow at a terminating end thereof;
- an insert plug, insertable in said insert opening.

A one way flex chain link, said one way flex chain link comprising:
- a unitary metal bar having a top, a first end, a second end, a tang space, a center point, and at least one elongated opening through a side of said unitary metal bar;
- said chain link first end being a clevis, said clevis having a through opening through the prongs of said clevis of predetermined size;
- said tang opening having a back wall, said back wall being beveled and having an insert opening therein;
- said chain link second end having a centered prong, said centered prong having a predetermined second through opening therein, said centered prong being configured to fit a clevis first end on an adjoining chain link;
- said chain link second end having an integrally mounted prow at a terminating end thereof;
- an insert plug, insertable in said insert opening;
- a lateral slit in said top of said unitary metal bar, from said top through into said elongated opening in said side of said unitary metal bar.
