This unique screen tool is extremely helpful when replacing the galvanized steel insect screen on your Hehr Standard windows. Since no spline is used on these windows, it is very important to get a good crimp around the flange on the outer edge of the window frames. The narrow 1/16" thick outer ridge helps push the screen mesh into the channel on the outer edge of the window frame.
The roller has a nice contoured hardwood handle and a quality steel ball bearing wheel.
Additional photos show a picture of a Hehr Standard window and a photo of the screen installed.
