Compatible with all EZ Marine Anchor Pullers. The 250-foot 3/8″ solid nylon mainline is the best diameter for ease of use and minimum drag. The 50-foot 3/8″ Multi-Filament Polypropylene (MFP) is a floating “tag” line attached to the 3/8″ nylon main. This keeps the puller from inadvertently floating off the anchor line. The line has also been designed to float, making it easy to reconnect your buoy.
