Knife latches

I have United Windows (made there in NJ) and I think it's model 4150. They were installed around 2004 and I recently purchased the home. I cannot keep the screens in the windows. I think the plastic ones might have been the originals. The last 2 photos (metal) also seem to work. 

The plastic ones seem to be 1 and 1/16" as opposed to 1" so wasn't sure if any of your latches would work. Could you let me know? Also, if there is a sturdier way to keep these screens attached, I would consider. I have cats and they keep pushing them out!

Thank you...I think they must have been pretty inexpensive windows but cannot afford to replace right now.

Thanks for reaching out to us, and for your patience during this busy season. I don't recognize these latches off-hand, but we may still have something that can work for you. 

Please give me a little more time to see if I can track this old model down and I'll get back to you ASAP.

I unfortunately couldn't find your exact knife latch. It might be just a little too old. 

That said, we sell two types you might want to consider: our 70-222 and 90-227. Review the design of these two parts and see if you think you could get them to work. You'll also find two videos below that may help you come to a decision.
