Hello I need bottom bearings and bearing holders as well as side muntins for Artium Windows. The house is 14 years old.

I am afraid we haven't had much luck locating this exact older Atrium Window Roller. We suggest our 87-164 as a replacement. With this part you will need to drill a hole for a screw to lock it in place. Take a look and let us know if you think this will work.

Looks like you recommend PN 87-164 for the original Astrium part
