Windsocks
Millard Towers offers a complete line of windsock assemblies:
Aviation Windsocks used for ICAO, FAA, and Transport Canada airport and heliport applications.
Frangible Towers used to support Aviation Windsocks where there is a risk of accidental impact.
Aluminum Windsock Poles used for all applications - Aviation, Explosion Proof, and Industrial.
Explosion Proof Windsocks used for offshore and onshore helideck platforms typical in the oil and gas industry.
Industrial Windsocks used at factories, railyards, farms, arenas, and other locations where a wind direction indicator is needed.
Fabric and Industrial Windsock Swivels can be purchased in our online store. For all other items, please contact us for a custom quote.
Millard’s aviation windsocks, also known as wind cones, employ the same engineering principles that have made its towers renowned. The windsock swivel is built with high-grade materials and designed for optimal performance. Assemblies have been stringently tested and are fully compliant with ICAO, FAA, and Transport Canada structural and photometric requirements. For your convenience, fabric windsocks can be purchased online at our shop.

Explosion Proof Windsocks are designed to give helicopter pilots a highly visible indication of wind speed and direction during landing and take-off in all weather and light conditions. For use on all offshore and onshore helideck platforms, the corrosion resistant illuminated windsock is rated for Zone 1 and 2 areas with gas explosion hazard and complies with Transport Canada TP325, ICAO Annex 14, and UK CAA CAP437 specifications. Made from high-grade materials and utilizing cutting-edge components, the assembly requires minimum maintenance - only a periodic visual inspection is required.

Frangible windsock towers are manufactured to ICAO and FAA frangibility specifications and made from high-grade Aluminum alloy. The unique lattice structure offers rigidity in high winds, but is yielding if accidentally impacted by an aircraft. The tower comes equipped with either a tilting base or an elevated hinge. Both provide easy servicing for windsock maintenance and replacement.

When frangibility is not required, Millard’s robust Aluminum poles can be used to support windsock assemblies. The design is not subject to warping or bending caused by long-term fatigue as is the case with other windsock supports. For servicing, all designs come with a tilt base that allow it to be raised and lowered by hand. An optional center hinge operates using a winch and allows the pole to be raised and lowered by a single technician without the risk of falling.
