5' L Personal Watercraft Shore Dock Extension by Black Widow PWC-EXT

Need a little extra length on your Harbor Mate Personal Watercraft Dock? No problem! The Harbor Mate Dock Extension will extend your dock out past shallow inclines so that you can easily load or unload your jet ski or other personal watercraft. This extension is manufactured in high-strength, lightweight aluminum. The stainless steel hardware is corrosion-resistant and maintenance free. It installs in the center of the Harbor Mate dock PWC-RAMP, and comes with a sturdy three-foot-wide foot for extra ground stability. Four rollers per side on the extension provide friction-free loading, reducing the risk of scratching your personal watercraft. This extension will add 5 feet to the center beam of your Harbor Mate dock. When installed, the dock and extension can support up to 1,200 pounds. The legs can be adjusted incrementally to compensate for different shore heights.
