I need to purchase these

Thanks for reaching out to us. We unfortunately don't sell this exact roller, but it's something we may be able to research and bring in for you. Before I can say anything for sure, I'll need a bit more information.

To start, can you show me a picture of this roller removed from the door in its entirety? Can you also supply precise, written dimensions? I'm specifically interested in the width and diameter of the wheels, as well as the distance between the two screw holes on the installation bracket. Make sure to measure from the center of each hole, not their edges.

Once I have that data I will do my best to track down a match for you.
