A plurality of corner posts positionable in a rectangular array, each corner post including a cylindrical tube positionable in a vertical orientation, each tube having a lower end and an upper end with a cap with a closed top positionable over the upper end and an extension member positioned over the lower end, the extension member being cylindrical in configuration with an internal shoulder adapted to receive thereagainst the lower end of the tube, the upper cap and lower extension member being formed with outwardly extending rings adapted to support corners of a screen, the lower end of the extension being formed with upwardly extending recesses for forming spring urged tangs therebetween; and a plurality of bases, each base adapted to receive the lower end of the extension member and positionable in a rectangular array beneath the posts and extension members, each base including a planar lower surface and a generally hemispherical upper surface with a vertical recess formed to extend downwardly from the upper surface for the receipt of the lower end of the extension member, the lower end of the extension member being formed with an annular projection with the lower end of the recess being formed with an annular groove for receiving the annular projection, and a threaded aperture with a threaded plug formed in the hemispherical portion of the base for filling the base with water during operation and use, and a plurality of apertures extending through the base constituting an annular flange.
