Stanley FatMax Pro Chalk Black 226g 47-822

The Stanley FatMax Pro Chalk Black 226g (47-822) is a premium chalk line refill engineered for use in wet and demanding job site conditions. Unlike standard chalk, the waterproof formula eliminates clumping in moisture-rich environments and snaps longer-lasting, more visible lines on wet surfaces — keeping your layout work accurate regardless of the weather.

The practical square bottle design prevents the chalk from rolling off work surfaces, keeping your bench or floor tidy and the chalk within easy reach. With 226g of black chalk, this refill provides plenty of capacity for large-scale marking out tasks on concrete, timber, and other building materials.
