FAS/Prime Grade Walnut represents the highest quality available in hardwood lumber. This grade is known for its long, wide, clear cuttings with minimal knots or defects, making it ideal for projects that require consistent color and grain. FAS stands for “First and Seconds,” and it’s typically used for fine furniture, high-end cabinetry, and architectural millwork where appearance matters most. Its clean face and superior yield make it a preferred choice for craftsmen and manufacturers looking for premium material with minimal waste.
