Need a new sliding door latch

Question

Hi, I need a new latch for this door. I've replaced it once already but don't recall the model number. I just need the piece inside. Not the handle. You slide the thumb latch down and it is suppose to lock the door. Mine is very loose.

I also need to replace the bottom rollers. Can you tell me how to identify the model number or style of roller? I really don't want to have to pull the door and remove a roller to find out what it is. I'd rather have the parts on hand and swap them out.

Also ... if I replace the rollers should I also replace the bottom track?

Thanks! Don

Hello, Don. The internal piece you refer to is called the mortise lock. Yours in particular looks like our 82-218. I'm pretty confident this will work for you.

I have some bad news about the rollers, though. The only way we can ID them is to see them out ahead of time. I know that's more of a project than you wanted to deal with, but it's the only way. That's just how patio glass doors are designed. If we can't see the roller, we can't find a match.

Specifically, we need to see the top, side, and rear. Dimensions would also be a big help.

Finally, concerning your track, you only need to replace that if it's in bad condition.
