upper clip for pella screen window
I'm afraid this is the only size that we know of. Pella rarely makes the same part in different ways, at least not in my experience. Can you tell me the exact dimensions of your original?
I'm sorry to say that we don't have another version of this clip. Truth be told, I don't think another version exists. The dimensions you gave us are identical to the clip we carry, and from what I can see Pella only makes this. I don't see any evidence that they made an alternate version.
If you are sure that your clip is different, then it may be something that hasn't been made in a long time. It's also possible Pella changed the design slightly and didn't tell anyone, which is something that happens in this industry. However, most companies don't do that unless the new design is interchangeable with the original.
Either way, we don't have another version of this clip. From everything I can see, the 70-220 is the only type made.
