Looking for a Patio Roller with a groove/slot

I am looking for rollers for my patio door and I thought that I had found them in your 81-030 model. All the measurements were the same. However, I noticed that there was no groove as best shown in pictures 01 and 05. I didn't think too much about it until I went to reinstall the roller and I saw that the groove was important as shown in picture 09. I am hoping that you can help me to find replacements that will work. I can find no name or model number on either the door or the roller. Thanks for your time.

Hello,

Your roller reminds me of the 81-154 except for the bottom tabs shown on our assembly, which might not be a problem as long as the rest of the specifications match up to yours. Take a look and see what you think. Thanks for posting!

Looks to be exactly what I am looking for. Next warm day I will remove my roller and confirm the dimensions and hopefully get this problem fixed. Thank you for your assistance. 5 stars.
