Thank you for your quality control. That is really appreciated.
I checked with many companies for this window part. This was the only company that had this very old window part. It match perfectly! They saved me a lot of money in doing my flip house by not having to replace the windows as most of the rollers in the home were missing or shoot.
These parts for a General Aluminum sliding window (General Aluminum is now defunct) fit perfectly, and the window operates as it should
This replacement part works well on my General Aluminum windows. Extremely overpriced though. These are probably made in China at 2 cents a pop.
