We have a couple rollers that may replace this, depending on your measurements. Start by looking at our 81-023, 81-278, 81-279, and 81-282. Carefully review the dimensions we show for each part to determine which would be the best match. I'm confident at least one of these will be what you want.

Unfortunately, it's not possible to identify the replacement roller you need for your door based on the sticker alone. The only way we can help is to see the original fully removed and shown without obstruction. We specifically need to see the back side, top, and sides. Please let me know if that would be possible.

Written dimensions would also be a huge help.
