The Patriot Low Profile Floating Dock sits close to the water surface for easy access in and out of the water. Low Profile Floating Frames are made from 6000 series marine grade aluminum and have gusset reinforced corners. The aluminum frames measure 48 inchW x 96 inchL x 4-1/2 inchH and use rectangular foam filled floats along with pilings or anchors to create a stable and versatile floating pier. Low Profile Frames are joined together using a heavy duty floating hinge that allow the frames to articulate and move with the waves. Frames can be bolted directly together in parallel or use the Floating Hinge Kit to add perpendicular fingers.
