Made the old-fashioned way by modern manufacturing here in the United States, these XL Pro Series tomato cages have been the trusted standard for generations of gardeners and tomato farmers. The rust resistant 9-gauge (3.9mm) galvanized steel wire folds open to a sturdy 18-inch square by 58-inch high support cage. Eight 10-inch long prongs anchor the cage for a minimum of 48 inches of above-ground plant support. When the gardening season ends, these cages neatly fold flat for easy, compact storage.
