The sprinkler riser extension raises the height of the sprinkler nozzle above tall grass or mature plants. The extension suits both male & female thread types. Compatible with Rainbird, Toro & K-Rain thread styles.The extension piece is always installed between the nozzle and either the sprinkler stem or shrub adaptor. Another great application is using the extension on a rigid riser in a garden bed. This allows an adjustment of the nozzle height to accommodate plant growth without having to replace the complete rigid riser.
