Need several plastic pieces

I'm not sure what plastic pieces it is you need. Can you show me a picture of the part in question?

I'm sorry, your new photos didn't come in. Could you try uploading them again?

Ah, I see. Looks like you need new widow glazing. I'm afraid I cannot identify what you have based on your picture, though; all glazing more or less looks the same while it's installed. I would go through our glazing section to see if you can find a good match here. It would greatly depend on the shape and size of the end profile.

That cracked plastic in your picture is definitely window glazing. Many Milestone 2000 Series windows have been known to use the 55-191, but you'd need to compare our information to your existing glazing to confirm.
