These Zinc Max Prop Anodes are manufactured by Sea Shield Marine and conform to Mil-Spec standards MIL-A-18001 to provide cathodic protection against corrosion in salt water.  These patent pending max prop anodes include an aluminum mounting ring insert providing better bonding and longer life.  Where other inferior brands let their max prop anodes burn off, our propeller anodes last longer and the diecast aluminum retaining ring prevents the max prop anode from falling off.
