Abstract
Described is a multi-roller snap ring with one or more rollers extending across a space defined by a frame and one or more rollers integrated within the frame of the snap ring. The multiple rollers reduce and mitigate the frictional wear and tear caused by a purse line being drawn through the snap ring during purse seine deployment and retrieval operations. In addition, a locking mechanism with a spring-loaded, sliding and rotating lock forming a portion of the frame and a stopper tab are disclosed.
