Silverline Glass Door Lock and Latch Replacement
Hello,
It looks like your door uses a handle set like the 82-086 but, unfortunately, we can't determine what mortise lock you'd need without seeing the original. Even if we did identify the correct replacement, there's a good chance that you wouldn't be able to install it properly due to the damage to the frame.
In cases like this, our best option would be to see if you could install something like the 82-005 surface-mounted handle set, which bypasses the internal mortise lock entirely. Keep in mind that adaptations such as drilling new holes in the frame will likely be necessary. Look over our video below to see what you think. Thank you!
Great! Just let us know if you have any other questions.
