There are a lot of possible matches for that patent. To be honest, patent numbers aren't the best way to identify a part, since they can cover a wide range of hardware. Start by looking at our 81-018, 81-149, 81-141 and 81-137 and carefully compare each one to your own part. If none match, please remove your roller from the door and show us pictures of it so that we can find a better match.

Hello there! The photos are actually a much more reliable way to narrow this down than the product codes. The 81-018 or its stainless steel variant, the 81-149, look very close. But look over the dimensions to confirm. Let me know if anything differs.
