Gavin Jeffries Snib Mouse. A Locksmith tool designed for drilling retaining screws on rim cylinders when snib is engaged on nightlatches. Once cylinder is removed, jig is reversed and there is another guide to drill for snib location, meaning there is no longer any need to smack case off the back of the door for access. https://www.youtube.com/watch?v=EtaR1PmdZao
