I replaced some existing Rand Bird 4inch popups with these. They deliver the additional height over the 4inch that I removed. Installation of these of a bit easier due to two choices of water inlet; 1/2 port on the button or the 1/2 port half way up the casing. The nozzle which comes with this sprinkler allows with 360 degree spray or it can be adjusted down along with a 20% reduction of water coming out of the nozzle to reduce the maximum spray diameter.
