Attention
To avoid intermediate shot twisting while in the anchor handling gear it should contain uneven number of links.
The intermediate shot is intended to be used in anchor chain configurations, for the manufacturing of bridles, chain slings, jetty fenders, power shovel draft gear. It consists of a series of chain links and has a total length of 25 m and 27,5 m. The stud increases link strength by 20%.
To avoid intermediate shot twisting while in the anchor handling gear it should contain uneven number of links.
