Drawer slide bracket

Thanks for posting. These style sockets have pegs that insert into holes in the back of the cabinet. They have to be gently pried loose. Sometimes they are glued into place, in which case you may need to use some type of glue solvent to remove them. A local hardware store might have a recommendation. For replacements, consider the straight 32-119 sockets, which mount with screws, along with the various-sized tracks I have listed on this page. Let us know if you have further questions.
