Lost trippers are the most common reason an Intermatic dial timer stops following its schedule, and extra trippers let one timer run more than one cycle a day. The Intermatic 156PB10398A is a package of two ON and two OFF plastic trippers. Intermatic specifies them for all P1100 series timers, the P1261P portable outdoor timer and the PB913N84 series mechanism. Why pool owners and service techs pick it Two ON and two OFF trippers in one package. Replaces missing or broken trippers on the dial. Adds a second daily ON/OFF cycle to the timer. Genuine Intermatic part for the P1100 family. Clips onto the dial with no tools.
