sliding vinyl windows

A home owner from USA says:
I have sliding vinyl windows that use something similar if not the same as the Q-LON QWS 530 and 440. I would like to know if you have and can sell these products and at what price. I have to measure my existing seals to determine whether it is 440 or 530.

Thanks for posting. I'm not familiar with those numbers, but when I cross-reference them I get our 58-056 and 58-170. Do these look familiar? Carefully compare the specs we show online to your own weatherseal and see how well they match up.

If they do not match, I will need you to remove a small sample of each of your own weatherseals and take a few pictures for me to see. Please make sure you take a picture of their profiles, just like how we show the 58-056 and 58-170. It's essential that we see their shapes.
