Hello,
We may be able to replace the corners themselves but we would need to see one removed from the door to compare to our replacements. As for the casing, that appears to be part of the door frame, which would be specific to the manufacturer. Thanks for posting!
Hello,
I believe that this is a door made by Bayform, which is no longer in business, so we will not be able to replace this hardware. You could try contacting local hardware stores that could have backstock of these parts from when these doors were at the height of their popularity. Thanks for posting!
