The Rotar umbrella holder looks like a circular-based prism with cuts or slots that diaphragm it, emptying it into height. In Version I the elliptical cuts are asymmetrical, while in version II these rise symmetrically to scan the side walls. It can be equipped or not with a steel container on its bottom to collect the deposit water. This would be housed directly in the lower part of the structure and emptied at the appropriate time, by lifting it. If used in outdoor situations, the complement can also receive a hole on the support part for the run-off of the run-off water from the umbrellas.
