A building entrance protector having a housing unit. The housing unit is provided with a plurality of walls and a sidewall, the sidewall defining an outer side and an inner side. A door is coupled to the sidewall and rotatable about an axis of rotation with the door defining a frictionally engaging edge. The door is positionable between a closed position and a secured opened position. A frictionally engaging member is mounted on the outer side of the sidewall so that when the door is moved from the closed position to the secured opened position, the frictionally engaging edge interferes with the engaging member to restrain the door. Additionally, the distance from the axis of rotation to the frictionally engaging edge of the door is less than the distance from the axis of rotation to a frictionally engaging portion of the frictionally engaging member.
