DIG's 0-14 GPH, 360°, Adjustable Drip Emitter on Spike is designed to produce a very low flow to gentle stream pattern with an adjustable flow rate of 0 to 14.1 GPH and a diameter range of 0 to 2.3 ft. at 25 psi. Available in two models, including model BA1B (pack of 4) and B10B (pack of 10). Each drip emitter has an adjustable cap that allows for simultaneous control of the flow rate and the wetting area. As your plants grow, the flow can be increased as the plants require more water to flourish.

These 360°, Adjustable Drip Emitter on Spike offer a convenient way to water areas where conventional sprinkler systems are not workable. Color: Blacks.
