Good Product, May Be Challenging To Install
These seem to work well for my sink setup. You need to make sure you have enough room between the back of the panel and your sink bowl so that the tray will fit. Also check that there is no sink mounting hardware that would interfere with the tray. Mark the cutouts on the back of the cabinet panels before you remove them! Doing so will help get the measurements correct for the panel/hinge attachment point.
Two tray installations took me about 1.5 hours to complete. I had to work through a slight issue mounting the cabinet panels to the hinge. However, the panels tilt out fine, now.
