Was in pallet I purchased. I know nothing about it but do believe that all the parts you need for it are included. You will have to have the other side for it to work but it is sold separately. Since I have not been able to test it personally I am offering a 7 day return policy incase anything is wrong to keep my customers happy . You have to purchase the other side for the lock SEPARATELY. So please if you purchase make sure that you understand this and know what all you need so you can't say that I didn't tell you it needs it. thanks.
