The TelosXL lift assist provides a safe way to vertically raise a kayak into a position where it can easily be loaded into the carriers. You can detach the Telos XL and use it on the other side of the vehicle to load your second kayak or store it in the trunk for unloading later. The new ground level adjustable extensions avoid contact with the vehicle's sheet metal and provide a solid base to gently ratchet the boat into the loading/unloading position. The DownLoader is our premium J-Style carrier with features for low clearance, ease of loading and universal fit for most load bars. These carriers also include corrosion proof frames, molded strap bales, replaceable base pads, replaceable upper sleeves and a fold-down design. The universal mounting system fits a large cross section of aftermarket load bars (round, square and oval) as well as most factory systems. Also includes 2-lengths of mounting bolts to achieve the best rack installation. Comes with cam style load straps and bow and stern safety tie-downs. The MPG352 TelosXL Lift Assist w/ DownLoader Bundle comes with assembly tools and complete instructions for transport of 1-kayak. All parts and product workmanship are guaranteed with a Lifetime Limited Warranty. Material: Aluminum.
