Details

The longest length boom that we offer, the 2.87m Tubular Boom meets or exceeds industry IEC 61400-12-1 recommendations for tower and boom offset distances. This boom cannot be shipped via UPS due to its length.

This heavy duty boom comes with mounting plates and u-bolts to attach the boom to the tower and uses our 16” stub mast for sensor mounting.

This boom can mount one NRG 200M Wind Vane or NRG 40C Anemometer right out of the box.
