Searching for A-750285

I'm afraid I don't know what you need. That sticker doesn't tell me anything about the handle. In order to help, I'll need a photo of the specific part you want to replace. Let me know if that would be possible.

Hello! These images are a huge help. At first glance your handle and mortise look like a match for our 40-211 kit, but you will need to review our dimensions to confirm that everything matches up.
