This catch is for L shaped extended 3 door corner units having two doors on one face and one on the other. These are ideal for breakfast bar returns etc., which reduce the cost of adding a small module to a standard corner unit. In this situation there may not exist a mounting situation for the side mounts keeper.
In this situation, the Top Mounting Support Catch keeper fixes to the mounting block, which is in turn fixed to the top of the cabinet. It suits both left and right hand applications.
This catch can be used in any other application as it can be mounted below any cabinet top or shelf whenever a strong but smooth action catch is required particularly when it is necessary to add a catch to taller doors for extra pull-in which can not be achieved by self closing hinges alone.
