Spline roller

A screen roller or spline roller is a small hand tool used to press screen mesh into the edges of a window frame that is fluted on the inner edges, or to press in the retainer spline that holds that mesh in place. Often these are combined into a single tool or combined with a spline cutter; versions are currently manufactured from plastic or wood and metal.[1]
