Horizontal aluminum poles used to hang half height skirts. They also serve as supporting "window sills" for zip down windows. Height is adjustable.
Please see "Half Height Skirts". For years we used the term "privacy skirts" to identify the 1/2 height skirts installed around the perimeter of a canopy. In an effort to be more descriptive and less confusing we will now refer to the lower 1/2 skirts as "Half Height" skirts.
Half height skirts create a perimeter barrier while allowing visibility into the canopy. These skirts can be individual or continuous. Individual skirts hang separately between each vertical support pole. Continuous skirts are connected with zippers and hide the vertical support poles. Half height skirts are sometimes referred to as "privacy skirts", "pony walls" or "bally curtains".
