The Item for sale is a spray arm set (pair) made for National Walking Sprinklers model B3 and Kees model 102. It includes a set of two spray arms with a tubing diameter of 1/2” and a length of 20 inches. The nozzles are machined and are as close to original that you can find. The compression connectors will already be installed and will have 3 threads showing after attaching to the Tee but are fully made up and do not leak. See my other auctions for more sprinkler parts including model A5 spray arms.
