Four Inch Cut To Height Plastic Sprinkler Riser

This four-inch sprinkler riser connects flush, spray, impact, and gear-drive heads directly to underground laterals via standard 1/2-inch male pipe threads. Pre-marked threads at one-inch intervals let you trim the unit precisely to your required elevation. The adjustable length keeps irrigation zones efficient while avoiding interference with landscaping.

Made from UV-resistant HDPE, the riser withstands seasonal sun and ground shifting without losing strength. Multiple units stack easily with compatible extensions to raise head height as plants grow. It pairs reliably with Orbit, Hydro-Rain, and similar brands for non-constant pressure outdoor systems designed exclusively for cold water.
