I-20 SHORT RADIUS NOZZLES
P/N 466100 (Black)
NON-REVERSING 360
This I-20 sprinkler is designed as a part- and
full-circle in one model. When the sprinkler
is adjusted to the full-circle position, the
sprinkler will rotate in a continuous counter-
clockwise direction. This saves everyone from
stocking additional full-circle only models
while efficiently irrigating the landscapes.
