One-sided WC knob No-Ha Locco

A privacy lock only visible from the inside.

“Locco” doorknobs have been specially designed for the NM 937 in order to retain the door’s minimalist appearance as much as possible. They are made of stainless steel and are used to lock WC door on one side. Other commercially available doorknobs may also be used, as long as the #6x6 square spindle is made of a non-ferrous metal. 

IIn an emergency, it is possible to open the door from the outside in a simple manner by sliding a sheet of paper downwards in the handle between the cover plate and the door where the lock is situated.
