Searching for Legance-Patio-Door 77 140012

Hello,

Your mortise lock resembles the 82-238, which is used with the 82-080 handle set. We also offer the 82-081 keyed version. With that being said, our handle sets use a base plate with side mounting installation holes to attach the inside handle, which yours does not have. Our handle set may still work but it is something to be aware of. Review the specifications below and see what you think. If you decide to give it a try and run into any issues, our return policy can be found here.
