Yes, screws and a foam gasket
I'm not aware of any finish other than the polished chrome.
The book spacing is diagonal so check your original. Some are side by side. The hole also has a notch in it for the spacer collar. It’s 1”
Screws included as well as the inside foam gasket
Hello DTs and thank you for your interest and support of Moen products. The Moen Posi-Temp Escutcheon Plate is used with a Posi-Temp valve. A Posi-Temp valve has a handle that will rotate only and does not pull out. The screws on the escutcheon plate are at 2 o’clock and 7 o’clock. If your current trim kit has 2 screws at 5 o’clock & 7 o’clock, you may have a standard valve. Our Standard valves are non-pressure balanced and have a handle that pulls out to turn on the water. With use of the Moen Standard Valve Adapter, part number 145058, you can adapt the valve to accept Moentrol Trim with a round plate. If your screws are at 2 o’clock & 7 o’clock and you have a push/pull handle, you can use any current Moentrol trim on your existing valve. You will need to verify your valve is a Moen valve to determine which escutcheon plate will work. If you have additional questions, please feel free to call us at 800-289-6636. Our current business hours are Monday through Friday from 8:00 am – 7:00 pm (EST).
