The Snappers can be added to any frame, and you don't have to buy special leaders. Making the casing from your existing leaders is easy-peasy. You don't even have to take the leaders off the frame. I just did it last weekend. She has a video showing you how to make the casing for the Snappers: http://youtu.be/uB0isjU4zz8
My leaders are serged along the edges. I measured the 3/4" from the serged edge. That way all I had to do was sew just at the serge line, and I did't have to worry about it fraying.
