OP, seriously, some scumbag knows whats inside your shed so expect them to come back. It doesn’t mater how massive your lock is, they will unscrew the door. If the door can’t be unscrewed, how secure is your roof? Got a shed alarm? So did I, but the nasty men (public forum) simply took the batteries out. Duh.
Seriously, if you can keep anything inside your house then I would, unlike Binners who chose to have no choice :wink:
