The RAILBLAZA QuikGrip paddle clip was designed to make it easy-to store your paddle, pole or even landing net. The universal design of the clip will fit most standard shafts from 1-1/8 in to 1-3/8 in. There is 2-3/8 in between screw holes and the track nuts are included. Paddle holder is 2-3/4 in W so your paddle will never come out. Because of the design of the QUICKGRIP paddle clip, you do not need a secondary clip to hold your paddle or pole. The QUICKGRIP paddle clip comes track mountable right out of the package. The clip stands out from your track 3 in to not crowd your interior space. The QUICKGRIP also offers the ability to mount the RAILBLAZA miniport rackmount to the hole between the thumb knobs, so you can add your favorite RAILBLAZA Accessory. While this is a track mountable paddle holder, it is also able to mount directly to your kayak if you so choose with locknuts and washers.
