SeaSucker's new Pro Series Paddle Holder does double duty by combining a paddle clip and a sturdy carrying handle in one, which securely mounts onto your board or boat with a powerful SeaSucker 4.5" vacuum mount. This unit comes with interchangeable clips to accommodate two different paddle sizes: shafts 25mm to 26.5mm in diameter, and shafts 28mm to 29mm in diameter (sorry, you might have to measure it IN METRIC!!! * cue dramatic music* ). Some assembly required.
