The wire trellis clips are commonly used in vineyards to firmly fasten and support drip line or drip tubing to wire, using the wire trellis clips every 4-10'. Place the wire trellis clip between each emitter so any low hanging points of the tubing will be where drippers are located. This will keep the water from drippers falling right where the dripper is located. If the dripper is right where the clip is holding the tubing this will be a high point and could cause the water to run long the tubing several feet away to a low point before falling to the ground.
Trellis clips may be used with any 1/2" sized poly tubing. Made of black UV-resistant plastic, these clips offer a simple solution for supporting drip tubing with drip emitters on wires along the vine rows.
