Trailer Receiver and Coupler Combo Lock Set, Keyed Alike, Class III & IV - Fulton - Tow Ready

I am well satisfied with the locks thus far. I have two concerns, however. First,I don't know how long the rubber cap over the receiver lock will last and second, we went to four or five key shops before getting duplicates made. I would also like to be able to buy additional coupler locks keyed alike so I could have one for each trailer.

What I ordered is what is pictured here. What I received was not Fulton, but some other brand, and had a round barrel lock, not the square one as pictured. It's harder to handle when your fingers are cold, and I'm just not satisfied with it. That's 2 for 2, and I will probably at this point not return as an I-boats customer.
