Searching for Jen weld sliding door latch

Hello! I'm not sure what you mean by door latch in this instance. Are you referring to the thumb lever that you flip to turn the mortise, or are you talking about the mortise itself?

We do sell the 82-030 handle set, which is a slightly different design compared to yours but should still work as a replacement. Just note that the hole spacing is 3-15/16" on center.

If I'm mistaken, please clarify exactly what you need and we can work from there.

Thanks! In that case, you can consider our 82-107. This is specifically designed to work on Legacy handle sets like our 82-086, though, which is just a little different compared to yours. I'm not 100% sure if the 82-107 will be compatible with your handle. The video below will allow you to confirm.
