Heavy Duty FLAT! Inflatable Fender. Made from Heavy Duty materials with Stainless Steel “D” rings located on the ends plus extra “D” rings on the edges, depending upon the size. Standard inflatable boat air valve for quick inflation and deflation. Purpose designed and built to accomplish the difficult task of protecting your stern or swim platform from bad docks or careless small vessel operators. The flat design minimizes the tendency of a typical round fender to end up under or on top of the platform due to wind and wave action, and with the multiplicity of “D” rings, it is easy to secure. The 8 inch thickness of this fender provides stern or platform protection without the awkward giant step sometimes necessary to negotiate embarking and disembarking from tenders and other watercraft. Because it is truly inflatable, it requires minimal storage space. Available only in Black.
