Unbranded Wood Handle Spline Roller (Better)

This spline tool is perfect for the installation of fiberglass, polyester, and aluminum window and door screens. With both convex and concave roller wheels, this is your all-in-one screen installation tool. Use the convex roller to roll screening into the channel of the frame. The concave roller can then be used to press the spline into the channel over the screen to secure it in place.
