The Boom Buster 437-R is a one-piece boomless spray nozzle with a 3/4" pipe thread, covering roughly 29.5 ft in a single wide flat pattern with no boom to fold, break or catch. Output runs 19–24 GPM between 30 and 50 PSI.
This is the Roadside (-R) version. It carries the same orifice and output as the standard 437, but produces a larger droplet so the pattern holds its shape at higher travel speeds — intended for ditches, medians, fence lines, right-of-way and dust suppression work.
