Description Reviews

K-Rain RPS75 4 in. Pop-Up Adjustable Arc Rotor

The RPS75 gear drive is designed for basic residential and light commercial applications and is a direct replacement for Hunter PGP rotors. The reversing mechanism, a K-Rain patented feature, is the same mechanism used in the Hunter PGP (K-Rain currently licenses this patent to Hunter - U.S. Patent No. 5,417,370 Carl L.C. Kah Jr.). With K-Rain's wide selection of standard and low angle nozzles, the RPS75 provides even water distribution.
