Thanks for reaching out to us. I'm reminded of our 26-088P. I recommend you review the specifications to see if they match what you need.
To install the 26-088P tilt latches, you must remove the top rail off the bottom sash. First, you need to remove the top corner screws which hold the sash together. After the screws are removed, carefully take the top rail off the window and glass. Be very careful not to damage the glass in the process. In some cases, you can push back the top rail off the glass. Try wiggling the top rail a little and if you have to, use a hand-held hair dryer on a low setting to soften up the adhesive that seals the glass to the frame. Then the top tilt slides into the top rail from the sides.
