These screen frame top hangers and latch are constructed of aluminum and come in a white painted finish. They are used for the installation of aluminum screen frames on vertical and horizontal sliding windows, such as on single hung, double hung and sliders. The hangers install with one nail-in fastener each, and they fit 7/16 inch thick screen frame material. The latch installs over your screen frame and locks onto the slotted head ball fastener that installs on the bottom sill.
