We need to include several rectangular areas in our sprinkler system.
These areas are 5 x 15, 4 x 14, and 4 to 5 x 17. The Toro catalog
illustrates side, center, and end strip patterns as all rectangular.
The Rainbird catalog shows the center strip shaped like a bow tie
(spraying wider from a narrow center) and the end strip as half a bow
tie (spraying from narrow to wide). If you've had actual experience
sprinkling rectangles, your advice would be appreciated.
