The PRO-SAFE DH-FLAG-18 is an 18-inch wide by 18-inch high vinyl warning flag designed to mark hazards, flag work zones, and identify service points in the field. The flag mounts on a 3/4-inch dowel handle and features a 1-inch inlet diameter for secure attachment. Overall assembly height is 24 inches. Constructed from durable vinyl in a high-visibility red and orange color scheme, this flag is built to stand out in both residential and commercial job site environments. It is a lightweight, portable marking tool for HVAC, plumbing, electrical, and general trade service crews.
This warning flag is suited for outdoor and indoor job site use where technicians need a quick, visible marker. Common applications include flagging open trenches, shut-off valve locations, excavation zones, and active work areas during service or installation. The compact 18 by 18-inch flag face provides clear visual indication without requiring permanent installation. Trade professionals across HVAC, plumbing, pool service, and electrical work carry flags like this as standard site safety equipment.
Designed as a general-purpose warning flag compatible with standard 3/4-inch dowel handles and 1-inch inlet mounting configurations common across job site safety applications.
No tools are required for standard deployment. Insert the dowel handle into the inlet and place or stake the flag at the intended marking location. Follow applicable OSHA or local authority job site safety regulations when deploying warning markers in active work zones. Retrieve and secure flags before leaving any unattended job site.
