Need replacement rollers for my 8 foot tall sliding glass doors

Need 1-1/8" tandem roller setups for dual pane Windowmaster sliding glass patio doors circa 1990. Panels are 48"Wx96"H. Original wheels were vinyl tandem. Need the same, but in Stainless Steel rollers.

This is an original tandem vinyl roller off of my sliding glass door. They have been replaced About 2 years after door installation) with steel wheels. The tech happened to have a pair of stainless steel tandem rollers, which he installed on one of our sliders. That door is operating as good as new after about 24 years. Wheels are 1.125" overall diameter with concave groove. I think I saw on your website that you have the same thing, but with 1.25" diameter wheels. Not certain if that would work.

As an addition to my reply from a few minutes ago, it looks like it's almost exactly your roller Product Code: 81-174. Except I would prefer to get that in stainless steel. Thanks
