Cavity Sliders

Here is another product designed and manufactured by a brilliant New Zealand company called Cavity Sliders.

This lock has pure form and function. It uses a 3 pin tumbler cylinder, effectively allowing pocket doors or cavity sliding doors to be key lockable as well as having the hardware slide effectively into the cavity.
