This piece broke

It's tough to tell what you have from a damaged piece, but it looks like it could be similar to our 15-192. This is a Certainteed brand part. Look it over and see what you think.

Please note that in some cases, the front bumps on our 15-192 can get in the way during replacement if you're working with a comparatively old window. Shaving them down may be necessary for ease of installation. Just something to keep in mind; products altered in this way are also not eligible for return.
