Tube fiberglass cleat base is an extra paid optional accessory specially molded for RIB inflatable tubes. Made of thick marine fiberglass with embedded premium teak panel, this bottle-shaped side platform solves the problem that soft PVC & Hypalon tubes cannot bear the tension of mooring cleats.It acts as a sturdy reinforced mounting base for stainless steel horn cleats, holding dock lines, anchor ropes and boat fenders without tearing the inflatable tubes. The flat teak surface provides a stable temporary storage space for fishing rods, cups and small marine gadgets. Besides practical functions, its streamlined integrated design greatly upgrades the luxurious appearance of your boat side. Reserved mounting holes support extra fitting installation such as rod holders and navigation light brackets, maximizing the side expansion capacity of your RIB boat. All fiberglass structures are anti-corrosion, UV-resistant and perfectly bonded to inflatable tubes for long-term saltwater marine use.
