Mortice Style Sliding Glass door lock

Hello,

In this case, I would recommend taking a look at the 82-005 surface-mounted handle set, which uses a similar internal lock and bypasses the need for an internal mortise. With that being said, take a look at our video below to confirm if you could follow the same process to install it. Keep in mind that this handle set has 4-15/16" mounting holes, which could require making new holes in the door if your original spacing differs from ours. Thanks for posting!
