NEW Traditional Hawaiian KU Trailer Hitch receiver insert Hawaii Smokin TikisAloha, this is a hand carved traditional Hawaiian Ku trailer hitch receiver insert produced by Smokin' Tikis. It will fit a standard 2" receiver opening. There is a hole in the block to insert a locking pin. These can be found at most automotive stores. Make sure you get one with a lock and key, not just a pin. It measures approx. 5" x 3 " and weighs approx. 2 lbs. If you have any further questions please feel free to contact me. Cheers Smokin' Tikis
