replacement pella sliding glass door handle

I'm afraid that we won't be able to supply this exact Pella door handle. In fact, I'm not sure if it's even still available. 

Would it be possible to re-tap the hole threads in the exterior handle and redo the threads? We do carry handles used on Andersen patio doors, like the 88-013 and 88-014, but these are meant for Andersen doors, not Pella. That's something to consider. You would need to drill new mounting holes and the base should cover up the old holes. You also have to be careful when drilling that you don't damage the door or glass. 

I'm sorry that we can't offer a better suggestion.
