Yes, on our SHIELDS® line, you do not need to have any extra hardware. You can use your existing hardware and gasket. We do not sell 1/4″ gaskets, please contact your OEM dealer. On select skid steers, we will provide our exclusive 1/2″ gasket (SHIELDS® Seal) with your original window. Please contact us to purchase a replacement for our non-milled windows.
