I have had this box many years. It contains screening for a car BUT I have had it for so long that I do not know the application. I am trying to clean up my stuff and do not want to just throw it away nor make any thing on it. If another Hammer can use it I will give it to them in person or just send it for the price of the postage Mercuryguy
They also come with spiral type springs that have a hook on the end. You push the spring in and engage the hook to grab the grill in several locations. The springs might be rolled up in your screen. Each screen is made for a specific car and application.
