Narrow applicator applies chemicals along edges

Apply chemicals along walkways, sidewalks, driveways, fences, buildings or along any edge without drift, spillage or overspraying. Narrow 4" or 6" widths apply chemicals only where you want to - so neighboring plants, sod and trees aren't damaged. Gravity fed shaft applies chemical directly onto the roller in a solid stream which keeps the roller completely saturated for a uniform, application. Made of chemical-resistant high-density polyethylene. One gallon capacity. Overall length 52". USA made.
