Sliding door handle has broken

Hello! We do sell this handle set, which looks like a match for our 82-080. The bad news is that it is no longer available in black. We've tried very hard to get this color option but it's just not something they make anymore. I apologize for the inconvenience. 

Concerning the damage your old hardware suffered, this is usually due to either faulty rollers or a damaged/clogged track. I highly recommend cleaning and lubricating your rollers and tracks to  make sure they're functioning properly. Also check for damage in case they need replacement.

Replacing rollers can be a bit of a hassle, so keep that in mind in the future. I would definitely lubricate the track at the very least to see if that helps.

We can only supply this handle in white or beige. Due to the unique design of this handle, there is also no substitute that I would feel confident recommending. This handle set is particular in that it uses those four screws that come in from the sides to secure it to the base. It also has a notable thicker thumb lever stem that differs from everything else in our inventory, which all have flat stems. 

I'm very sorry that we don't have an alternative option.
