High-visibility marking flags manufactured from flexible PVC film mounted on a high-carbon alloy steel wire staff. The visible flag area is approximately 4" x 5" with a 21" steel wire staff option commonly used for utility locating, landscaping, irrigation layout, and temporary boundary marking. Flags are glued to the staff for improved durability; flags are available in APWA colors and in bulk packaging (bundles of 100 and cartons of 1,000). Presco technical documentation provides material properties (3.2 mil thickness, impact brittleness to -40°F) and lists standard sizes and staff options.
