The Telos™XL temporarily attaches to J-style carriers (DownLoader and J-Loader) and V-style carrier (SeaWing). This lift assist provides a safe way to vertically raise the 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.
