Wall anchors are devices used to secure objects to walls, providing support for items like shelves, mirrors, or heavy frames. They work by distributing the weight of the object across a larger area of the wall, preventing damage and ensuring stability. Common types of wall anchors include toggle bolts, plastic anchors, and screw anchors. When installing a wall anchor, it's important to choose the right type based on the wall material, such as drywall, concrete, or brick. Proper installation ensures that the anchor can hold the intended weight, making it a crucial step in home improvement and organization projects.
