In any construction site, there must be markers placed that will contribute to the overall efficiency and safety of the job site. The simplest and most cost-effective marker to set up at the site is the marking flag. Each colored flag provides a clear message to surveyors and engineers. For high-quality blue marking flags, choose only the Presco 2″ x 3″ Marking Flag (Blue) for 21″ Staff 2321B.

This marking flag is dyed with bright blue ink for high visibility in either dark or brightly lit areas. Its color can last a long time and can resist tear from windy weather conditions, even in job sites with temperatures below -40 degrees Fahrenheit. Instead of wrapping it around the staff, the flag should be simply glued to it in order to ensure optimal performance.

Among construction professionals, blue flags are known to mark potable water lines. These flags will help prevent the lines from getting damaged and flooding the area.

For the best setup, the Presco 2″ x 3″ Marking Flag (Blue) for 21″ Staff 2321B should be paired with a steel wire or plastic flag staff from Presco. Available for order here on Engineer Warehouse, an authorized distributor of Presco products and more.
