Toro - 35-2631 - 570 6 in. Stationary Riser/Shrub Adapter

This Toro 35-2631 is a riser, so it threads into the bottom (inlet section) of a Toro spray head to give you an extra 6" of rise. They're often used along with 1/2" pipe fittings.

Yes, these parts will screw together. They are meant to be used in between a Toro spray head and a Toro nozzle to add more height to the riser.
