Low-Velocity Windsocks


Orange Windsocks	Orange Windsock Kits

Orange/White Windsocks	Orange/White Windsock Kits

These lightweight windsocks react to the slightest wind movements.

Windsocks—Individual windsocks come with mounting ties.

Windsock Kits—Windsock kits come with everything you need for mounting, including an inlet frame, pole, mounting ties, and brackets.

Inlet Diameter—To replace an existing windsock, you must determine the inlet diameter. Lay the windsock flat to measure the inlet and multiply by 0.63 for the inlet diameter.

Wireless Weather Stations

Monitor nine different weather conditions up to 1,000 feet away. The outdoor weather sensor measures outdoor temperature, humidity, wind speed and direction, rainfall rate, total rainfall, barometric pressure, heat index, wind chill, and dew point. It wirelessly transmits readings to the console by radio signal. Console has built-in sensors to measure indoor temperature and humidity. Console can be placed on a desk or mounted to a wall.

High-Velocity Windsocks

Use these sturdy windsocks to track stronger wind movements than low-velocity windsocks.

Inlet Diameter—To replace an existing windsock, you must determine the inlet diameter. Lay the windsock flat to measure the inlet and multiply by 0.63 for the inlet diameter.

Inlet Frames—Inlet frames are sold separately.
