Broken Sliding Basement Window

A quick learner from Neillsville, WI 54456 says:
Window pane measurements 27 1/8" wide by 11" tall.

I found stated on window: Series 400 Deluxe Slider Basement Unit

Hopefully you can see problem in pictures. Looking for replacement piece that keeps immobile glass in place. It broke at the screws. Vinyl seems to have gotten brittle from age. I was attempting to replace screen when piece broke.

Windows were in house when we purchased, so not sure where/what company purchased from.

Any help appreciated!

I'm afraid I don't recognize the manufacturer. You could try a builder's supply house or mill work nearby where home builders buy their material. They won't have that exact piece, but maybe the complete window. If you just need to hold the window together, see a local hardware store for a strip of flat aluminum where you can cut to size and screw on to the window.
