Rain Bird 21A sprinkler heads 

Glad these worked out! They run well.

Thank you for sharing these, they are good steady movers. I do not like the canister models too much, because the canister gets in the way for me to enjoy them, but they do serve the purpose in a large yard of environment.

Nice 21s. I have one myself. Need to get the 31 now.

O my god! That’s the same sprinkler model I saw in a dusty box that was there for a whole year!
