I Think I'm Looking For Product Code: 26-234

Hello, can you confirm my part to be product code: 26-234? These parts would be for my mother's windows. The measurements I've come up with are 2" long, 7/8" wide, 1/8" thick at the ends, and 5/16" thick at the center where the notch / ridge is.

Unfortunately, I can't measure the section where the actual clips are which penetrate the window opening because they are broken and not there and I only have one sample of these parts from my mother's house which is 65 miles away. Any help that you can provide would be greatly appreciated. Many thanks.
