Secure the seatpost hitch to the tow bar with the hitch nut.
Please note, as we run out of product, none of the remaining hitch nuts have the lanyard strap that we added earlier this year. If you want to make you own, drill a small hole in the hitch nut and use fishing line to loop through the hitch nut. Until they run out, you can also choose a New Hitch if needed.
