Rigid risers are offered as an assembly and are available in two configurations. The first configuration is the riser mounted into a 1/2″ male threaded adapter which can screwed into any 1/2″ FIPT PVC fitting. The second configuration is a riser mounted on to a 8″ tall stake with 1/4″ barbed inlet that accepts standard 1/4″ poly or vinyl tubing. Riser lengths of 6″, 8″ and 12″ are available with both configurations. Threaded jets or micro-sprinklers are screwed into the top of the riser.
