Hull Anode Type 15 - ZincFor sailing on salt water or brackish water, we recommend the use of zinc anodes. Cathodic protection by means of anodes is a must for the protection of all metal parts under water. Therefore, not only for steel boats, but also for wooden, fibreglass, and aluminium hulls, anodes are required. The material of VETUS zinc anodes is of the highest possible standard, the U.S. mil.-A-18001 K. specifications. Anodes that do not meet these specifications have little or no effect at all.All VETUS anodes are streamlined and mounted either with specially made studs, which can be welded to a steel hull, or special through-hull bolts for fibreglass and wooden boats.Specifications: Material: Zinc Type anode: Hull Type of contour: Rectangular Weight (kg): 1.1 Length (mm): 150 Height (mm): 25 table.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; } Truck Freight: No Oversized: No
