The 2" x 2" (51 x 51 mm) diameter steel ball bearing roller on our CRL Steel Flat Edge Roller is riveted to a steel yoke, and mounted to a contour-grip, finished wood handle. Use it to smooth out flat spline or glazing vinyl prior to insertion in the frame.

Helpful Tip for Rolling Fiberglass Screens: Before rolling your spline (with screen wire), into the bottom of the spline groove on the first pass, use this Steel Flat Edge Roller Tool to first seat the spline into the top of the spline groove. Once you have the completed the entire frame, go back and use your Concave Edge Roller to finish inserting the spline with screen wire. This method helps to eliminate some of the hourglass bow-in of the frame caused by rolling the screen too tightly into the frame.
