A regularly shaped column has a perfectly straight edge from ceiling to floor. A 6inch x 6inch support post or, a 2ft x 2ft square-base stucco column would be examples of regularly shaped columns. Regularly shaped columns are easy to seal to. The column has a straight continuous edge and the side binding of the curtain has a matching straight edge. The side binding can easily seal against a regularly shaped column using marine snaps or magnets. It is perfectly fine to have 2 separate curtain panels meet and seal independently to either side of a regularly shaped corner column.

An irregularly shaped column does not have a perfectly straight edge from ceiling to floor. Examples are fluted, spindled, tapered, or bungalow-style columns. Because the straight edge of the curtain will not match the non-linear edge of the column, you cannot achieve a good seal. Instead, you must seal curtain panels to other curtain panels as described in Sealed doorways & fiberglass rods. If at all possible, you should NOT have 2 curtain panels meet at an irregularly shaped corner support column because a corner panel-to-panel seal is weak.

If you choose, you can have a panel-to-panel doorway at an irregularly shaped column that is not on a corner (to hide the seam behind the column) and, in fact, even latch on to the irregularly shaped column. The panel-to-panel doorway gives you your seal, and a marine snap securing one of the side bindings to the irregularly shaped column will add stability. Click any photo to enlarge.
