For the garden, we focused on sprinkling in a fan shape and chose this instrument. However, it was no use trying to connect to the hose used at home after obtaining it without thinking about how to connect to the hose. I consulted at a nearby home center and found no exact parts. At a later date, the catalog is sent and I am amazed at the number of parts. I think that it would be nice if you could fill in the description of the parts of the joining tool.
