1800 riser extension

Nope, the shaft extensions are for RainBirds pop up sprinklers such as the 1800 series. What you need is a 1/2 inch threaded coupling and a short 1/2 inch riser. 5-6 inches long.

Rainbird 1800 EXT 6" Spray Shaft Extension

The description of the Rainbird 1800 EXT 6" Spray Shaft Extension is confusing to me. I plan now to use Rainbird Spray Nozzles to water my schrubs. The current spray heads are mounted on 1/2 inch risers that I would like to replace and extend 6 inches. The description of the spray shaft extension states it "screws onto the shaft" and the "nozzle is attached to the top". Am I correct in assuming the the bottom of this extension is 1/2" female thread and will screw onto a 1/2 inch shrub stick with male pipe threads that is currently in place.
