This is for a single-hung window.

I could not find any identifying markings, etc. Pictures are attached.

Length 30" and width is 1/2".

Thank you for submitting your pictures, Tom.

We're going to need a few more pieces of information from you before we continue.

First, since your channel doesn't include any stamps, please give us the weight of the window sash so we can determine what strength you'll need.

Second, please take a look at this attachment guide and see if you can identify your bottom attachment:
