I'm looking to replace a lock on the door of our downstairs loo but it's a
strange one that I can't find in the usual diy places.
The door is a sliding door and the lock, instead of a solid bolt, has number
of interlocking fingers. When you turn the key, some of these fingers come
out and turn left, the others turn right, locking themselves into the hole,
preventing the door from being slid open. I don't know what this type of
lock is called, let alone know where to get one. Can anyone recognise it fom
my sketchy description and suggest a source?
