A wall guard, also known as a wall bumper or wall protector, is a device designed to protect walls from damage caused by impacts. The purpose of a wall guard is to act as a shield by absorbing or diverting the force from accidental collisions, reducing the risk of scratches, dents, or other types of damage to the wall surface.

1. Commercial Buildings: In high-traffic areas such as corridors, lobbies, and hallways, wall guards are often installed to protect the walls from damage caused by carts, trolleys, luggage, and other moving objects.

3. Educational Institutions: Schools and universities frequently install wall guards in busy areas like stairwells and corridors to prevent damage caused by students' backpacks, lockers, or moving furniture.

4. Parking Garages: Wall guards are commonly used in parking garages to protect the walls from accidental bumps and scrapes caused by vehicles.
