A two-dimensional high-density apple training system, often referred to as a “fruiting wall,” provides many benefits to the fruit grower. In this video, we will discuss how to construct a durable trellis that will hold up to the stress of windy weather and heavy crop loads.

Penn State, I thought I went there, but my wife said it was State Pen, I know i didn't see any apples.

At 3:10 you list a wire tension stress of 200-250 psi. That seems extremely low for wire that's rated to 200,000 psi (according to the label you show). For 12.5 gauge wire, this works out to a tension of about .37 pounds. Seems really low.

Levi, Thank you for your question. It may be the terminology that is confusing. We were explaining the recommended tension to apply to the wire and not the breaking strength. We recommend the wire be tensioned to 250 pounds to ensure that it is tight enough to remain straight and provide support for the trees. The actual breaking strength is over 1540 pounds per strand. If you think about this for an animal, for example, the 250-pound tension is how tight the wire should be so the animal will be held back. If the wire tensioning is lower, it will be very slack and the animal will be able to climb between the wires and escape. Tara Baugher Extension Educator, Tree Fruit Penn State Extension
