Prime-Line G 3071 Nylon Housing With Steel Roller Assembly (2 Pack)

Fits some early 90's dual pane aluminum windows i have. Exact fit.

I have to say I’m very pleased with these. Makes the windows slide like new!

These rollers were a direct replacement for what I needed. They worked out very well...

We have aluminum sliding windows that are about 30 years old. The windows are double pane and quite energy efficient and they still look fine, but they have become almost impossible to slide. I decided to try a new roller assembly. This fit our window perfectly, and installation took less than ten minutes: simply unscrew the two old rollers and fasten down the new one. Voila! The window rolls like new. We had already had estimates for new windows, and the cost was about $1300 per window. The new rollers were $6!

I measured the broken rollers on the bottom of the window. These are a exact replacement. Now the windows (4 )slide easily. No more having to muscle and drag.

The product fit

Measurements of these are accurate. Fit our windows exactly. The wheels do wear down over time, unavoidable. Good idea to keep windows tracks clean and lightly lubricate these annually. I use 3-in-1 oil. We open our windows daily during 5 months of the year. These last about 5 years. Our windows are 3'+ tall dual panes, so are fairly heavy. These hold up well, given the beating they take. The plastic frame will eventually crack if they are in a dry climate like SW US.

Worked as described for replacing old worn out rollers.
