Marking Whiskers are a sturdy marking choice for survey and construction sites, underground utility locating, property boundaries, athletic fields, trees and landscaping, and other locations requiring a stable marking solution. Virtually indestructible, these APWA color-coded Marking Whiskers spring back up when run over by lawn mowers, graders, and heavy equipment. They are easily and conveniently attached to wood stakes or by a 60-penny / 6d nail (not included). Use them alone or in conjunction with other marking products. Point marking is an essential part of all surveying. Having a reliable and long-term tool such as this industry standard can be invaluable whether you are in construction, land surveying, landscaping, or athletic field management. Also known as stake feathers, stake chasers, stake trackers, and bristle flags.
The American Public Works Association, a non-profit professional association, created a uniform color code for utility companies, both public and private. The colors have become the marking standard across all industries.
