Window Screen Hardware are the devices that hold your insect screen into your window. There are many different types of hardware based on the many different screen applications. The most common type of hardware is the corner/tension springs opposite pull tabs. Plunger bolts, a spring loaded metal bolt, is also a common type of hardware. It is best to match the hardware that you already have on your window screens. If you need ideas for hardware, or to see how each type works, please watch our video below.
