Thank you for posting. I'm afraid we don't have any closet door roller with this style that has a 4" spacing between the vertical screw tabs. It looks like you're only using one screw, anyway, though. With this in mind, could you use our 23-028? Check it out and let me know what you think. Make sure to confirm that your wheel is concave.
