Certainteed Window Plugs

I have a CertainTeed bay window that is about 12 years old. It consists of 4 window panels joined together. The joining screws are covered with small plastic plugs that are about 7/16 inch across and plug an opening about 3/8 of an inch.

My two 10 month old puppies decided it would be fun to pull several of those plugs out and destroy them. I did not find any that were removed and do not want to take one out to determine the length of the plug because it might not stay when reused. I have not been able to find anything that would work locally and would like to get about a dozen. I hope you have received the photo.

I have the same problem. My windows are not white. They are an almond color. The plugs just fall out--no puppies involved. :-)

I have looked everywhere for replacement plugs but to no avail. Are these plugs available in other colors? The plugs in my windows are also 7/16" in diameter.

Thanks for your help!
