Multipoint mortise lock system and handle 5820.170 and 6.264

Question

Hello. We are looking for a replacement for a multipoint mortise lock, plate and handle for a Simonton sliding glass patio door.  The patent numbers for the lock are 5820.170 and 6.264.252. The length of the internal lock is 10 inches from end to end. Would we also need a new lock plate attached to the wall for the internal lock to connect to?

Hello! Looking at your hardware, I recommend our 82-087 handle set and 82-239 mortise. I believe this hardware will work well for your door.

You can probably reuse your old keeper, but if you find that it's not compatible then the 82-249 is what we usually recommend for the 82-239.
