12" (304.8mm) pressure washer curved gutter cleaner. Simply attach the gutter cleaner to a pressure washer wand or lance with the 1/4" (6.35mm) Quick Connect (QC) plug input and attach a 1/4" (6.35mm) QC spray nozzle to the 1/4" (6.35mm) QC coupler output. The curved fitting allows the user to clean gutters from the ground and blow out dirt, grime, leaves or anything else that may be stuck inside. Recommend using a Washing (white) 1/4" (6.35mm) QC spray nozzle with 40 degree spray pattern unless dirt and grime are caked on hard.
