sales and repair sliding glass doors

I'm afraid this mortise lock isn't really used for one door in particular, or even one door more frequently than others. There is no way we can determine what rollers you have based only on knowing that your door has the 82-239. The only way we can figure out what roller you need is to see your current roller removed from the door.

I know it's frustrating, but that is the only way to be sure. Door manufacturers don't want to make it easy for you since they'd rather you just replace the whole door entirely. That's not necessary, of course, but it does require a bit of homework; there is no easy reference, unfortunately. We have to see your existing rollers out of the door in order to find the best match.
