Abstract
Abstract A household refrigerator door is locked in its closed position by a latch, which is rotatably mounted in the door and moved between its locked and unlocked positions by a key. The latch cooperates with a catch, which is mounted on the cabinet exterior of the door gasket. The catch includes a mounting plate which is integral with a portion receiving the latch. The mounting plate is secured to a wall of the cabinet by screws extending through slots in the mounting plate, through elongated holes in the wall of the cabinet and finally into threaded holes in a nutstrip. The slots enable the mounting plate to be adjustable in one direction, and the elongated holes enable movement of the catch in a second direction orthogonal to the first direction.
