Hello, I am looking for window rollers for 2 radco series 800 weather lok windows. Not sure about the correct size or dimensions. Also the last picture shows the top of the window with a plastic pin, not sure if there is supposed to be a roller there too?

Thank you for your help.

Hi Paul, this looks similar to SWISCO product code 87-193, 1/2" diameter roller with axle pin. Carefully compare the measurements and let us know if they differ in any way. Sometimes the same rollers are used in the top of the window sash as well; it may help keep the window rolling smoothly within the frame/track. You could try just replacing the lower rollers and see if it glides smoothly.

The 87-193 roller has a wheel that is 1/2" in diameter and 3/16" thick. The nylon pin is 9/16" long by 5/32". It's not exactly the same as your dimensions but it's close. I'm honestly not sure if it will work for you, but it remains our best match.
