The GARDENA Oscillating Sprinkler OS 90 can be positioned higher with the 20-cm-long GARDENA Extension Pipe. The Extension Pipe is mounted between the sprinkler head and foot. This allows convenient irrigation of taller plants from above. The GARDENA Oscillating Sprinkler OS 90 can irrigate square and rectangular areas as part of the GARDENA Micro-Drip-System and is excellently suited for kitchen- and ornamental gardens. Two Extension Pipes are included.
