Mortised sliding screen door handle/lock 1974

Hello,

We can't be sure without seeing the position and orientation of the internal locking hook, but the 82-002 would be a good place to start. Keep in mind that these are intended to be used in sliding glass doors, so we can't make any guarantees, but review the specifications below compared to yours. Thanks for posting!
