Manufactured in Fort Worth, TX... Our windsocks and frames have become a staple in the Oil & Gas Industry, serving to protect workers against airborne hazards, passing OSHA’s Oil & Gas Rig Inspection Checklist for Drilling & Well Servicing Operations required in American Petroleum Institute (API) RP 49 Section (8.2.3)

For Airports, Airfields & Heliports our windsocks meet FAA’s Advisory Circular No. 150/5345-27D.

Windsocks are made from 100% Nylon stitched with heavy duty polyester thread for added durability. For strong reinforcement at the throat, #2 brass grommets are set in double thick heavy polypropylene webbing.

Frames are galvanized using 1/4" steel round rods with SCH 40 pipe swivel bases. The swivel is made to fit over a 3/4" mast/pole with two set collars. The entire frame is powder-coated to prevent rusting, guaranteed to rotate freely with zero maintenance required.
