The body of the plastic latch is 2 5/16" long without the extended spring loaded prong. Each window has a right and left hand latch. The latch has a tab that inserts into a channel at the corner of the window frame to retain the latch and prevent rotation of the latch. I can't find identifying marks, numbers, or manufacturer names on the frames .

Thanks for posting. Could you confirm your tilt latch's dimensions? Compare them to the 26-351 and see if you think this matches what you need. Let us know if the dimensions differ, and if so, how.
