Watersports Flag Holder (Wakeboard Tower) It's been difficult for boaters with wakeboard towers to display water sports flags effectively, until now! Instead of manually holding the flag, stick it into the holder and your flag will fly high so that other boaters can see it. It also frees your hands to tend to other activities. This one-size-fits-all water sports flag holder is designed to attach easily and fit perfectly on most OEM and aftermarket wakeboard towers. It is crafted from billet aluminum, then polished and anodized. Stainless steel hardware, polymer collars and adhesive backed pads are provided for quick and easy installation onto all wakeboard towers, 1 5/8" to 2 7/8" diameter, including Malibu's new elliptical Illusion towers. No drilling required!
