ABSTRACT:
A trellis arm and a support wire therefor. The arm has a hole in the first end to swingably attach the arm to a trellis post and a notch in its second end to receive the trellis wire. The support wire overlies the outer end of the arm, extends under the trellis wire and is attached to the top of the trellis post.The support wire may be in the form of a continuous loop.
Various types of trellis arms have been proposed for supporting grape trellis wires but these trellis arms have not been as simple and efficient as is desirable.
