The distance between nozzles on the Chapin 4-Nozzle Poly Boom (6-7782) is about 17 inches apart. The distance between the end nozzles is 51 inches. The width of spray will depend on how far the boom sprayer is off the ground.
We contacted the manufacturer Chapin, and they stated that while the Chapin Poly Boom 6-7782 could work on the wand for the Chapin 97902 12 Gallon Push Sprayer, it would not be able to attach directly to the tank to spray in that fashion.
We would recommend reaching out to Chapin directly to confirm if the Chapin 4-Nozzle Poly Boom (6-7782) would work for another brand of sprayer. They can be reached at 1-800-950-4458
