Holman 30mm Pop Up Sprinkler Riser Extension - 4 Pack

The Holman Pop Up Sprinkler Riser Extension raises the height of the sprinkler nozzle above tall grass or mature plants by 30mm. The extension piece is always installed between the nozzle and either the sprinkler stem or shrub adaptor. The Pop Up Sprinkler Riser Extension is also great for use on a rigid riser in a garden bed, as it allows an adjustment of the nozzle height to accommodate plant growth without having to replace the complete rigid riser. Suitable for both male and female thread types and compatible with Rainbird, Toro & K-Rain thread styles.
