Internal Lock system for Silverline window 10" Mortis length

Question

Hello,
Somehow from going to bed and getting up our sliding door internal lock broke or was hung up. I needed a locksmith to come drill it out. It took 3 hours. I need the internal lock parts for this. I think by my original M/I Builders paperwork this is a Silverline 5800 Series. It has the double locking hooks. I'm trying to identify any potential part numbers. There are no order #'s or stickers anywhere on the slding door. thank you. - mike

Thanks for writing in! Your internal mortise lock looks a lot like our 82-265. To confirm that this is the right replacement, take a look over the dimensions from the diagram. Carefully compare them to your existing mortise lock.
