Abstract: A unitary shelf support and retainer is disclosed and includes means for mounting the unit on a cabinet wall, a surface for supporting the cabinet shelf, and an upright portion extending along the wall of the cabinet and including a smoothly curved deformable web of resilient material. As the shelf is installed, that web is deformed to a degree permitting the shelf to slip past the web to be supported by the shelf support surface. After the shelf has passed the deformable web, it returns to its original shape, owing to its resilient nature, in position to retain the shelf in place.
