A Securistyle storm stay 400mm heavy duty 16mm A140 coastal is a type of window hardware that is used to help keep a window secure and in place during adverse weather conditions, such as high winds and heavy rain. The storm stay is a device that is mounted to the window frame and helps to hold the window securely in place when it is closed. The 400mm measurement may refer to the length of the storm stay or to the size of the window it is intended to be used with. The 16mm measurement may refer to the thickness or diameter of the storm stay. The heavy-duty designation may indicate that the storm stay is designed to provide extra strength and support for the window. The A140 coastal designation may refer to the specific design or performance characteristics of the storm stay, such as its resistance to corrosion in coastal environments. Storm stays are often used in combination with other window hardware, such as hinges and handles, to provide a secure and reliable mechanism for opening and closing windows.
