Power distribution box assembly for a vehicle

A power distribution box assembly comprising:

• a housing having a side wall bounding a cavity;
• a cover having a peripheral wall bounding a top wall, the top wall configured to cover the cavity, the top wall having an inner surface;
• a first latching mechanism having a tolerance configured to allow the peripheral wall to clear the side wall when the cover is rotated onto the housing, and a second latching mechanism disposed opposite of the first latching mechanism and selectively operable between an engaged positon and a disengaged position, wherein in the engaged position the cover is closed onto the housing;
• and
• a rib disposed on a top surface of the side wall of the housing, wherein an elongated portion of the side wall having the rib extends along a direction extending from the first latching mechanism to the second latching mechanism and wherein the rib abuts the inner surface of the cover when the first and second latching mechanisms are in the engaged position so as to eliminate the tolerance in the first latching mechanism.
