S1010 Round Hole Nozzle National Kees Walking Sprinkler Fits All Models.

These are not original National brand. The treads are DIFFERENT than the original. You can cross thread them into your existing arms or cut about 3/4” off arms are re-tap for these. Nothing wrong with using a lubricant and just cross-threading them in my opinion. These are 1/8” nozzles.

Sale is for two (sold by the pair) nozzles.
