Description

It is constructed with 3 types of thread-holder slots, thus suitable for mechanical lifting of wires:

• Buttonholes type A
  Open at the top with lug not protruding from the profile, recommended when using spring spacers or movable wires. Double positive effect: no damage can be caused to the beaters of the harvesters, and no damage is caused with prepoters to the buttonholes.
  They allow an initial manual raising of the wires, avoiding damage to young vegetation, and also give the possibility of mechanical intervention for subsequent wire raising.
  The weight that insists on the wire (due to shoots, leaves, grapes, wind) is no longer supported by the protruding lug, but distributed all along the pole; thus it is the pole that carries the weight, not the lug.
• N-type buttonholes
  "N" shaped with anti-hook characteristics particularly suitable for vineyards in hilly areas with counter slopes.
• H-type buttonhole
  Buttonhole positioned toward the base to facilitate the hooking of wires at rest.
