Shelf and closet hardware include parts and components that support and reinforce closet shelves and rods. This hardware helps maximize storage space and keeps items organized and out of the way when not in use. Shelf brackets come in different shapes and sizes to support shelves. Shelf supports are smaller than brackets and have a horizontal lip that supports shelves with lighter loads. Closet rods install in closets and provide an area to hang items. Closet caps fasten to walls to support rods and help prevent hangers from sliding off of them.
