Casement window parts
Hello,
Since your casement hinge track is 13", I suggest taking a look at either the 36-049 2-Bar Hinge Set or the 36-004-14 Stainless Steel 2 Bar Hinge Set. Both of these hinges have 14" lengths but they should still work fine as a replacement. Unfortunately, we do not carry a hinge with a 13" track length.
Take a look over each of their dimensions and compare them to your existing hinge to determine which of these might be the closest match. Keep in mind, you may need to drill new installation holes to install these tracks. In that case, we do strongly advise being careful not to drill to far into the frame, cracking the glass.
