  • Fence post
    Patent number: 6612550
    Abstract: A fence post includes a weighted base and a vertical member. The vertical member has a first end and a second end. The first end is secured to and extends substantially vertically from the weighted base. A float is provided that is axially movable along the vertical member from the first end toward the second end. A stop is spaced from the first end to limit travel of the float along the vertical member. This fence post is suited for use in wet areas, as it floats with the weighted base keeping the fence post in a stable upright condition.
