Nailer Strip

A horizontal strip of solid wood or plywood mounted inside the back of a cabinet box at the top and sometimes bottom, providing a secure attachment point for screwing the cabinet to the wall studs during installation. Nailer strips (also called hanging rails or mounting rails) are typically ¾ inch thick and run the full width of the cabinet. They must be strong enough to support the combined weight of the cabinet, its contents, and countertop above.
