Attention
Connecting links do not show equal strength in all directions and must be operated at loads directed along their axes (lengthwise).
The connecting link is an anchor chain component used to connect chain shots into a complete anchor chain. It is manufactured by hot stamping with subsequent machining.
Connecting links do not show equal strength in all directions and must be operated at loads directed along their axes (lengthwise).
