This is a 4 brick Chubb wall safe. It is fitted with a lever lock that can be a problematic pick. Fortunately I have recently invested time in practicing how to pick these locks. The investment paid off as the safe was open in a few minutes. No damage and I replaced the lock so the customer could continue to use the safe. The safe was fitted high in the wall. It was pretty awkward, arms outstretched above my head. Picking in a stress position is never good!
