<-----pulls retainer out.....those richdel solenoids aside from the retainer havent changed in YEARS and will fit almost any richdel/toro/irritrol valve out there starting with the old green richdel 205 to the very popular (altough i dont know why) irritrol 2400 "jar top"
forgot to mention one other thing, the o-rings throughout the years have changed a bit on these solenoids, shouldnt be a problem but worth mentioning, make sure the new solenoid screws in easily without a cross thread and there are no leaks around solenoid base. HAND TIGHT ONLY if you have to tighten more to stop any leaking something is wrong.
