Peachtree Sliding Patio Door Replacement Rollers
Hello,
Unfortunately, there is no standard replacement roller. Peachtree is especially difficult because they've been out of business for quite some time and most of their hardware no longer exists.
There's a chance that we may still be able to help but we'll need to see your original roller uninstalled to confirm. While most doors have two screws on the bottom side corners of the door frame, there are other possibilities; sometimes the installation screws are on the bottom, for instance. If that's the case then you'll have to remove the door completely from the frame to check. A good indicator would be for the adjustment screw to be on the face of the door at the bottom. Thank you.
