Concrete spacers for walls are small plastic or metal devices used in construction to maintain a precise spacing between the reinforcement bars and the formwork during the casting of concrete walls. They are designed to ensure that the reinforcement bars (rebars) are held in the correct position, allowing the concrete to flow around them evenly and without obstruction.
