Review: Works great - Used these on a half-door for a trailer I was building. These do need to be welded on but they are extremely satisfying once installed correctly. I used both latches on one door so the door doesn't go flying open on the freeway if one of them fails. Couldn't be happier!
Review: Excellent Parts - Welded them on my smoker pit. They worked perfectly.
