Abstract
Abstract A device for preventing debris from clogging downsprouts (22) and underground drain pipes (26) consisting of a cap (32), screen (26), and base (34). This device totally screens and contains the water flow. The screen (26) is easily removable by sliding the cap (32) up over the downspout (22). The amount of debris accumulation can be easily observed because either the cap (32) or base (34) is transparent.
