Rain Bird LG3HE In-Ground Impact Sprinkler with Click-N-Go Hose Connect. Provides all the advantages of a professional grade in-ground sprinkler with the convenience of a built-in garden hose quick-connection. Installs flush with the ground surface anywhere in your yard with no trenching required and covers up to 5, 200 square feet. Set it once for all season operation; provides 3"pop-up height to clear tall grass and retracts out of sight when not in use so you can mow right over it. This heavy-duty impact has the strength and performance of industrial/commercial products yet is easy to install and operate. Pop-up impact sprinklers are long-lasting and particularly well suited for performance with heavy-mineral content hard water and well water that can clog and corrode other sprinklers. Brass weighted "Water Saver" PJ spray guide arm controls water-stream and prevents side splash onto buildings and walkways. Arm is double-weighted for slower rotation and increased distance of throw up to 41. Heavy-duty, high impact case with sturdy reinforced ribbed design. Rolled lip design aids in setting proper installation height, prevents grass and weeds from growing into head, and minimizes backwash. Grit proof bearing for reliable operation and heavy-duty stainless steel retract spring for reliable pop-up and retraction. Full circle (360) or part circle (20 to 340) coverage with infinite pattern adjustment. Spacing from 26' to 41' apart. Designed for wide pressure range from 25 to 50 psi.
