Master Lock 379ATPY Universal Trailer Hitch Lock, Black

Great product

Bastante práctico de usar y te da más tranquilidad de los distintos tipos de candados para cople este es mi favorito

At first I thought it didn’t fit my hitch - to telly my fault. There are no instructions with it - just the picture on the outside of the box. I didn’t think to list the lever on the hitch so the lock would rest inside and then once I closed the lever I understood how it was supposed to work. Then turn the key and go. 👍.
