Introduction
The FLX35 and FLX55 series full and part circle rotary sprinklers
are designed specifically for golf course applications.
Manufactured from durable, high-strength engineering plastic and
stainless-steel components, these sprinklers incorporate many
innovative and time-proven features for lasting, maintenance-free
operation.
Prior to installing the sprinkler, read through the recommended
installation and start-up procedures. Please observe all Warnings
and Cautions when installing and operating this equipment.
