The 6-inch Stake Chase brand marking Whiskers are trusted for their durability and flexibility. Designed to provide maximum visibility and withstand multiple passes of a grader blade, is perfect for road construction. Over the years, however, these safe and easy-to-spot Whiskers have also become a prime choice for marking buried utility lines, survey points, and even athletic fields. 6" Stake Chasers can be easily hammered into a wooden stake or quickly fit onto a 60 penny (60d) nail.
