The BooneDOX J Cradles give your kayak great support, and they give you peace of mind riding down the road. The J-Cradles are welded out of our customary Air-Craft grade aluminum. The Upright measures 24" and the front angle measures 8", providing plenty of surface space to hold small and larger boats in the cradle. Both pieces are protected by high-density foam pads, and covered by our weather proof sleeves. The J-Cradles are rated to safely hold kayaks up to 125 lbs. in weight. The J-Cradles were designed specifically for the BooneDOX KT, but will attach to various other items using the four U-Bolts and their reinforcement tubes.
