Hey there,

Thanks for reaching out! Given the dimension and design of your mortise lock, it looks like it could be our 4-5/8" 82-226. Be sure to confirm the other dimensions from the lock to confirm that this is the right replacement. If you are looking to replace the handle set as well, this part is sold separately.

The patio door roller resembles our 81-182 SS Patio Door Tandem Roller. To determine if this is the right fit, carefully look over the dimensions and compare them to your roller. If yours differ please confirm the written dimensions of your roller and I'd be happy to recommend a better replacement solution.
