Been trying to look for some wardrobe locks on Screwfix and have hit a
complete blank.

What I am after is to place the lock on the internal side of the
wardrobe door, rather than embedding it in the door frame. Then have a
hole through the door for the key.

But I can find nothing suitable on Screwfix. Anyone point me in the
right direction. My main problem is that I don't really know what this
type of lock is called.

Thanks,

Graham
