Abstract: This new versatile invention of pool cover dome support system keeps the bugs, dirt, rain water, snow and leaves, out of the above ground pools or in-ground pools cover during winter. The system consists of a central distribution hub assembly, edge of pool clamps assembly and versatile telescoping poles. The central distribution hub assembly can be elevated above the rim of the pool to any desired height. The pool cover is disposed over the dome structure and secured around the pool whereby objects and substances will not accumulate on the pool cover. The system can also be adapted and used as structure to provide a temporary shelter for many other applications. The objective is to provide one universal substantially rigid lightweight structure at a low cost with minimum parts that can be assembled as a dome regardless of pools size or shape.
