Product details of Gardener's Supply Company 75 inch Bean Trellis, TJ7MRU:

Grow an incredible amount of beans with our tallest, strongest and sturdiest bean trellis tower. The secret is thicker supports coupled with 10" legs that hold the structure securely in the ground. The Bean Tower in our test garden yielded a fantastic harvest between mid-July and late September — in just 1-1/2 square feet Supports are 5 mm thick with 3.5 mm crosspieces. Openings are 7-1/2" square to allow easy harvesting.
