I'm looking for a stainless steel tandem sliding glass door roller assembly 3/4"
inches wide 1 1/8" inches tall with 1 1/4" inch rollers
Pretty much the same directions as your item number 81

I agree, the 81-030 roller assembly closely matches your dimensions. The only difference is that the top hole on our 81-030 will accept a #10 sheet metal screw, but I believe yours accepts a machine thread screw. It's something to keep in mind.
