  1. Susan

    This mail box was a direct drop in for the old mail boxes – no retrofit on the mail center was required at all. I really love having the option of the engraved doors. The old mail boxes that I am replacing had some numbers missing – it’s just so much nicer to walk by with residents and prospects and see no problems. The company is awesome to work with!!
