Abstract
A method of applying weights to the legs of instant pop-up canopies and the like is disclosed. The weights help prevent uplift under windy conditions. Each weight case is comprised of two half-round hollow cases. The case halves are joined by hinges on one edge and latches on the opposite edge. Each case half has a full length inner V-groove, which when closed, create a throughbore for the canopy legs. Each case half top is fitted with a filler hole and cap. The hollow cases can be filled with a variety of weight material. The weighted case is wrapped around the lower leg of the canopy and latched shut to secure the weight around the canopy leg. The weight case rests on the flanged footplate of each leg. Four to six weight cases are required for each application.
