Product review (5 stars): These work perfectly!
I really like these latches!  I have a beautiful freezer in my garage.  The bottom portion is the freezer and the top portion can be used as additional freezer or turned down to use as a spare refrigerator when needed.  I have rented out a room in my house and given the top of the freezer set as a refrigerator to my tenant.  He loves that he gets the whole thing to himself, especially after his last place where he was given a 10- inch square portion of shelf.

Unfortunately, he has a bad habit of opening my freezer portion (he uses the freezer inside the house so has nothing in this freezer) and not pushing it shut all the way.  Twice, I have discovered it left open and had to throw away all of the freezer contents!  I was not happy.  A friend mentioned locking the bottom portion with an outside lock and I can't believe this didn't occur to me.  I was a little concerned that it would not adhere to the front door of the freezer because it is textured with a diamond plate design, so it is not completely flat.  It worked perfectly and I now keep it locked all the time.  I love that my tenant cannot accidentally open it now.  He wouldn't steal from me, but he is extremely absent minded and I do not want to go through another hassle of replacing everything again.
