I've got to get a new lock for the shed, the one I have now mounts on the inside of the door, it has shoot bolts top and bottom and several in the usual place.
Looks the bees knees for a shed door lock. I entered "atra lock" into google images and found loads of pictures which could follow up to sales outlets. However half the pictures seemed to originate from plckpicking sites so either it is not very good so a ready target or it is so good the lockpicking lowlife like to yap about it.
