This was a replacement for the original box, whose latch was broken on delivery. The replacement has the same issue. The problem is that the clasp or lever is the exact same shape is the bracket. As a result it is difficult to only pull on the clasp. If you pull on the entire mechanism the entire latch and bracket pulls away from the box. The entire mechanism is simply screwed into the plastic and easily pulls off of the box. This is a very poor design.
