For irrigation of medium-sized lawns, this product can be combined with T100 and T380 turbine pop-up sprinklers and R140 square sprinklers. It is vandal-proof due to its memory function, allowing the sprinkler to automatically find the sector originally set. It features four optionally switchable nozzles with different water flow rates for even irrigation when sprinklers with different irrigation sector settings are used in combination. The integrated strainer and reliable, sand-resistant turbine gearbox ensure durability, with an internal thread of 1/2".
