ZHC-4 Divers Dream Slotted Hull Anode, Zinc, 1/2 X 4 X 6 Inches, Sea Shield Marine

This is a 'Divers Dream' slotted hull zinc from Sea Shield Marine.

It's model ZHC-4.

It's a solid block of zinc, measuring 1/2 inch thick, 4 inches wide, and 6 inches long.

It's designed to bolt onto your boat's hull or running gear to prevent corrosion (cathodic protection).

The slots are for the bolts to mount it securely.

If you own a boat kept in saltwater, you know how important these sacrificial anodes are.

They corrode instead of your expensive prop and rudder.

This is a new, ready-to-install anode.

Simple bolt-on protection to keep your boat's metal parts safe from electrolysis.

A must-have for any saltwater boater.
