Replacement patio door hardware

Question

I have an older glass patio door .. has a storm, screen and the main glass door.. the outside door used roller 81-004 but the inside door is way different. I was hoping it would be the same roller assembly but it's totally different.. the Adjustment screw is like a worm gear with a wedge inside behind the wheel. The adjustment is in the front bottom rail .. the sides has an hex key (3/16) I to hold a small aluminum block
Still can't find out who makes this slider and why didn't they use the same rollers ugh

Hello,

We'd be happy to help but we would need to see your roller assembly fully removed from the door, along with written-out dimensions, to compare to our inventory. Thank you.
