Abstract: A golf cart canopy attachment includes a shield which has a pair of guide channels formed on a top surface. A raised portion or dormer is formed between the channels. The channels engage corresponding guide channels in a golf cart roof to enable the shield to slide with respect to the roof. A pair of locking grooves are formed on the shield for preventing further movement in either a fully extended or fully retracted position. Stop blocks are provided on side walls of the shield to prevent further outward movement of the shield in the fully open position. A rod extends from an underside of the shield from which a pair of curtains extends. The curtains are moved along the rod on opposite sides to be connected together when the shield is in the fully opened position. When a shield is in a closed position, the curtains are pulled back to stored positions and fastened onto roof supports at the rear of the roof.
