Here's another garden trellis that has worked out beautifully to support tomatoes and cucumbers on netting with compostable trellis clips.
There are two parallel sections which are 6' apart with a path between the beds. Each is 7' tall and 6' between vertical poles. The verticals are anchored inside by 2' x 1/2" steel rods pounded into the ground.
By the end of the season, the tomatoes will be very heavy and a previous homemade trellis (not MakerPipe) collapsed. This system is so flexible we can easily add braces to prevent that if needed. Great product, well made and easy to use.
