Constructed with a tough LLDPE/HDPE shell and completely urethane foam-filled, it provides excellent buoyancy and durability in harsh water environments. Galvanized steel 5/16″ top eyebolt with 3″ hoop allows secure attachment, while a bottom swivel ensures the mooring line remains free of torsion. The 1″ blue reflective band enhances visibility in low light or high-traffic areas.

    • 5/16″ heavy-duty eyebolt with 3″ hoop on top (Galvanized steel)
