Anchor supply tubing in place and position the emitter near the root of your plant with the 1/4 in. Tubing Support Stake. The 4 in. stake has a hook on top for 1/4 in. supply tubing or an emitter attached to tubing, such as a button dripper, inline dripper, or Take-A-Part flag dripper. Stake pierces into the ground and lifts the emitter above soil or mulch to prevent particles from entering and clogging the emitter. Ideal for flower and vegetable gardens, trees, shrubs, and container plants. This tubing support stake is made of acrylonitrile butadiene styrene (ABS) treated with UV inhibitors.
