Feature and Benefit Highlights
• US Government-approved ROOTGUARD
®
protection uses the non-toxic
TREFLAN
®
that creates a force-field effect, guarding against root
intrusion by diverting root growth away from the emitter outlet
• Drip In
®
PC self-cleaning emitters provide precise, trouble-free
water application
• Flexible, sturdy design to fit into unusual spaces
Additional Features
