We appreciate the doors are not very strong / a lock would only be a mild deterrent for kids at best. But that is all we want really - something to stop kids (or nosy guests) opening big sliding wardrobe doors in the hallway. These are used for general storage, not day to day clothes.
Also with ours, if they are adjusted properly, you can't lift them off the track without loosening the tensioning system behind the door. So you can't just lift up and pop them out.
Could you just screw an eyelet on the door and one on the wall and put a cheap padlock (combination would be easiest) through them? If its simply to stop kids or nosy guests that might be a super cheap and simple idea. Ugly though.
