Apologies, my original request D97694 said casement in error, I am in search of parts for my slider windows. I added additional photos for the roller assembly, I am thinking 87-147 but not sure if measurements make sense. NEW ITEM: I think that other part is the keeper as it stops the window from opening when the latch is all the way down. Thank you for your help in identifying these parts.

Thanks for contacting us! The first roller to come to mind is our 87-010 , but I'm not entirely sure this is a match. I would carefully go over our measurements and see what you think. As for the keeper you show, see our 90-140 . This is often sued with our 90-139 lock.
