This is a door stop from Union. Please note that it is the type that is embedded in the frame. Use it for entrance doors, interior doors, etc. When not in use, it can be stored under the floor. - Product Number: UT 60-DCP - Manufacturer: Union - Manufacturing Date: 2015 - Material: Stainless Steel - Quantity: 2 Thank you for viewing. I purchased this for construction, but I am selling it because I didn't use it. Although it is unused, it has been opened, so I will consider it as "like new."
