The ¼ in. x 4 in. micro tubing stake is used to secure and stabilize the ¼ in. micro tubing with emitter near the plant, inside pots or baskets. The ¼ in. micro tubing stake is ideal in securing button or flag drip emitters at the end of 1/4 in. poly or vinyl micro tubing. Not recommended for securing ¼ in. drip line or soaker hose.
