The Tolsen 40048 is a specialized radiator brush designed for precise painting in tight corners, joints, and other hard-to-reach areas. Its curved head allows you to navigate awkward angles that a standard flat brush cannot reach, making it a practical tool for detailed trim work or painting behind pipes. This 25mm wide brush features a blend of 50% PET and 50% white synthetic fibers, providing a balanced bristle consistency for smooth application. The bristles are securely held by a chrome-plated stainless steel ferrule, which resists corrosion over time. For comfort during extended use, it is equipped with a fine polished wooden handle that is ergonomically shaped and includes a hanging hole for easy storage in your workshop.
