Patio umbrella poles are usually a good deal smaller than the opening supplied in a patio table. This difference means that it is easy to insert the umbrella into the table, but it also means that there is often a large gap between the shaft and the table. This opening can cause the umbrella to lean awkwardly, to rub against the table edge, to making annoying noises, and can scratch the finish off of the umbrella pole. The easiest fix for this is the patio umbrella cone! These clever little devices fit around your patio umbrella shaft, and create a solid, snug connection between the patio table and the umbrella.
This article looks closely at the patio umbrella cone, and reviews a few different brands of these clever little devices.
