The irrigation industry's standard for residential landscape sprinkler component protection. Large enough to house up to four 1-inch valves or drip control zones, the box provides easy access, durability, and flexibility. With its 12-inch height, the box reaches well into the frost-free zone in most climates. With the addition of one or more standard extension boxes, it can easily accommodate 18 in. mainline projects as well. The large access holes at each end of the box permit usage in meter applications. Multiple Color Options are available in green on black and sand, allowing you to match the box lid to the landscape for optimum aesthetic effect. It is also available in purple on black to indicate a non-potable water source.
