I was applying boracare on a timber frame and so wanted a nice wide fan, 6" or 8" wide. This did the trick for me. Glad I got it when I bought the sprayer, based on other comments here. I think it paid for itself the first day in terms of helping me make the most efficient use of the expensive product I was applying.
Purchased this nozzle thinking it would work better than the adjustable nozzle, the adjustable covers about the same area as the fan. Bottom line don't think I would purchase it again i would just stay with the adjustable nozzle.
