When the swell picks up and you need something that won't pull free from a rock face, 10 mm prongs do the work. This REEF 4-prong hooks onto underwater structures and holds. Hot-dipped galvanised finish keeps it looking right — and functioning right — season after season in Australian saltwater. Prongs come straightened out of the box. You grab, you deploy, you're done
