My biggest criterion in selecting this particular box was that it had a NON-locking lid. If you need a storage box or file box (which this officially is) that you can get into and out of frequently sometimes the locking features get in the way. Also I m using this box for an outdoor application. The lid extends beyond the walls of the box so rainwater will not go inside no matter what. Also very economical some comparable boxes were more than twice the price!
