An adjustable catch mechanism is described. The mechanism has a housing that has one or more side walls and a face plate. The face plate has an opening therein such that said opening communicates with an interior portion of the housing. There is a front plate adapted to be positioned over the face plate. The front plate is provided with an opening that is generally aligned with the opening in the face plate and shaped so that a catch means can retractably pass through said opening. An adjustable plate is positioned in said housing and has a base section with a top surface and a bottom surface. The adjustable plate is prevented from undergoing rotational movement in the housing and the base section has a threaded portion that is adapted to receive a threaded member on a mounting frame. The mounting frame has a base with a top side and a bottom side and wherein the bottom side of the base has the threaded member extending therefrom into said threaded portion of the adjustable plate and wherein the top side of the mounting frame has catch means and wherein the height of the catch means may be adjusted when the catch means is pushed into the housing and rotated. The rotation causes the threaded member to change the height of the catch means. The front plate helps retain the adjustable plate and the mounting frame within the housing.
