Slider and Door Handle Help

This looks like part of our the 82-080. The inside pull of this handle set has three components: the pull itself, the base of the pull, and then the mounting plate beneath that base that connects to the door. We do carry the mounting plate on its own for purchase, our 82-108, although this doesn't work with older versions of this handle set, since the dimensions tend to differ. That said, it appears you are showing me the second component I mentioned, the base of the pull. I am afraid we do not sell that separately from the 82-080. Apologies for any inconvenience. 

That said, it's not too surprising to hear your inside pull was damaged. A poorly running door tends to cause damage to the inside pull on a handle set. It's possible that both the rollers and the track need to be cleaned or even replaced. If you need to replace the rollers, we'll need to see them out of the door. The width and height of the assembly, as well as the diameter of the wheels, will help narrow down what you need. See the video below.
