SWISCO - The Replacement Hardware Authority

Unknown window brand tilt latches

A quick learner from Miller Mo says:
I have read several of your posts and think I have narrowed down the latch to one of two sets. I see 26-243/244 and 26-390/391 appear to be the latch. I do not know what brand the windows are nor could the two local window shops figure it out. We tried a Primeline F2734 but it buckles and does not sit flush. I think it is too long on the under sided grooves.

What I do have is Pat#5.139.291 which is how I found your amazing website along with the number 75 at one end and the letter "D" on the back side. Here are some pictures too. I have 12 of these windows and all the latches are going south. Any help will save me from buying all new windows over broken latches.

Looking at your pictures, our 26-243 and 26-244 look closer to what you have. The 26-390 and 26-391 are far too thin. I recommend carefully going over the dimensions we show for this hardware to your own latches to confirm.
A quick learner from Missouri says:
Perfect fit. I am making a bigger order today and sharing the source with our local hardware store too. They had nothing close and several others also have been looking. Thank you for saving me thousands changing windows out due to irreplaceable latches. Now I can keep the windows and spend the money on something nicer.
