Abstract: The invention is an adjustable bracket for supporting items on the railings of house decks. The bracket is formed of only two parts without any fasteners. The parts interlock, but can be adjusted to form a clamp around the typical rectangular cross section rail. One part is a support unit which is a simple strap with two bends in it to form two offset sections, and the second part is a clamp unit which is a hook shaped strap with a long leg and a short leg. The preferred embodiment of the connection is a slot formed in the long leg of the clamp unit into which fits a tab protruding from one section of the support unit.
