Abstract: A universal support bracket is constructed to adjust to various heights and volumes of flower pots and other containers and to adapt to hanging on wood and wrought iron railings and wood and masonry surfaces. A shallow channel with slots in the web is formed into a right angle, and a strap with a series of holes and an end hook fits into one leg of the angle between the sides of the channel. Screws passing through the slots in the web and the holes in the strap are used to attach the channel to a back support and to also clamp it tightly against the strap, locking the hook over the top edge of a side of the container. A "U" clamp is used around both the angle and the hooked strap to attach the bracket to an upright of a wrought iron railing.
