I just recieved a 10 inch and a 13 inch wind sock. Be aware that the photos show many grommets around the ring to place on the pole, but each I recieved only have 6 grommets. That being said, they still should work to replace our worn out socks.
Have been trying to find a red and white windsock for a while! This is a well made product and it is good to have a choice od sizes. There is some assembly required and a mounting ring is needed but a set of jubilee clips are provided for this purpose. This is more sturdy than the one it is replacing which has been shredded by the wind!
