No need to worry about a tilted riser with the Snap-in Stake. The 17 in. long stake has a built-in holder to snap the rigid riser in place and keep it upright. Gives the emitter attached to the riser additional height for overhead irrigation. Insert the stake into the ground by hand; for harder soil, carefully pound it into the ground with a hammer. The stake is made of durable ABS plastic treated with UV inhibitors.
