Rear Bracket for sliding shelf

Hello, 

The part shown in your photo resembles the old-style Merillat socket that hasn't been made in many years, unfortunately. The good news is that our 32-119 works well as an alternative. The only catch is that you will need to drill new holes for this to install into the back wall of the cabinet since it doesn't plug in like yours. Review the specifications below to confirm that the height and width of the opening will accommodate your track sides. Thank you!
