You are correct. I found the
15-195 on thew Swisco site after I made the inquiry.
The
15-195 was a perfect fit and a perfect fix.
Note...for my particular vinyl window I didn't even have to spread the balance bar slot.
I just rotated the T-Lock Balance Shoe 90 degrees so the brake was pointing up and down, with the top pointing towards the opposite side jamb, slipped it in to the balance slot, rotated the cam face towards the bottom jamb, installed the balance bar and done...all set for the window.
The whole repair took about twenty minutes total for both sides, including re-installation of the window.
