A TGS Exclusive

The RCA™ (Rotating Cross-Arm) Trellis System from TGS is the ultimate system for commercial blackberry operations. It’s built to last — including a 25-year warranty — and it’s built for success. It’s the ideal way to add more diversity and profit potential to your vineyard.

The unique rotating cross-arm design and cane training processes of the RCA System:

  • Improve yield of marketable berries
  • Protect canes from winter temperatures and winds
  • Position the fruit on one side of the canopy, reducing harvest labor by 33% or more
  • Promote a more open canopy for improved sun and air movement
  • Reduce the risk of sun scorching and overheating
  • Allow fruit to dry faster and more thoroughly after a rain
  • Fruit can remain on the canes 1-2 days longer before harvesting


The RCA System’s multiple positions allow for easy adjustment during the growing season to maximize yield, reduce harvest labor time and protect canes during winter weather.
