The PRO-SAFE DH-FLAG-18S is a vinyl mesh warning flag designed to mark hazards, equipment, and work zones in trade and industrial settings. The flag measures 18 inches wide by 18 inches high in bright orange mesh vinyl, making it highly visible in outdoor and indoor environments. The overall assembly stands 24 inches tall, with a 1-inch inlet diameter and a 3/4-inch dowel handle for easy attachment to pipe, conduit, or rebar. Plumbers, electricians, HVAC techs, and general contractors use flags like this to comply with OSHA and site safety requirements when marking open trenches, protruding hazards, or active work areas.
This warning flag is suited for residential and commercial job sites where temporary hazard identification is required. It attaches to standard pipe and conduit ends commonly found on plumbing, electrical, and mechanical installations. The mesh vinyl construction allows wind to pass through, reducing flag stress and keeping the marker visible without flapping loose. It is sold individually and is well suited for flagging open pipe ends, trench edges, or low-clearance obstructions during active construction or service work.
Designed for use with standard 1-inch diameter pipe, conduit, or rebar ends commonly used in plumbing, electrical, and mechanical trade applications as a temporary safety marker.
Slide the inlet opening over the end of an exposed pipe, conduit, or rebar stub to seat the flag in place. No tools are required for installation or removal. Position the flag so the orange mesh panel is fully extended and visible from the direction of approach. Follow applicable OSHA and local site safety guidelines when marking open excavations or protruding hazards.
