What kind of clips are used to attach inside storm windows. The screens have their clips attached but the stoms do not.
Welcome to the site. I googled this just to see. It looks like you will just have to figure out what works. https://www.google.ca/search?q=storm+window+clips&tbm=isch&tbo=u&source= univ&sa=X&ei=hy-JUra6Gsn8igKj94CgAw&sqi=2&ved=0CDQQsAQ&biw=1464&bi h=794
Not sure how anyone would know without a picture to see what you have.
It's rare to see inside storm windows.
The windows probably have same clips and screens. Look for a manufacturer name on the windows and call them.
