Megafend solid core fenders are available in all the standard marine sizes and are performance engineered to withstand heavy use. Each has an outer covering of quality Sunbrella® marine fabric with black being the standard color. All standard models use a 25mm (1") pvc pipe through the center. An optional stainless steel rod kit is available for conditions where extreme service is the rule. Our stainless kit is equipped with a ring over each end. Specialty sizes and over 100 colors are available on request. We'll also recover your existing fenders, even if made by others, when needed.
