I'm looking for a door lock suitable for a cavity slider that can be locked/unlocked from either side regardless of what the other side is. Sounds confusing???? Let me try and explain, and please see attached photo... we have a cavity slider between our main bathroom and our guest room (Bedroom 4), like a Jack n Jill bathroom or a Poor Man's Ensuite as they're sometimes known by, and I need a lock for it so that if there are guests they can have the door locked from their side but if someone else uses the bathroom it can also locked from that side.
