Modern Sliding Door Privacy Lock
The HB690 from Halliday+Baillie of New Zealand is about as simply stated and ruggedly built a solution as you will find for a modern pocket door lock. This one is 7-1/2" high, though there's a taller version as well as models with keyed entry. And it comes with a small but sturdy recessed edge pull. Finishes are highest quality: Marine grade 4 Satin Chrome, Polished Nickel and Satin Nickel as well as an Oil Rubbed Bronze model. Doors need to be 1-1/2" thick or more.
