You can never be too safe. The appropriately named Add-A-Lock lets you add a lock to almost any door that opens inward. This highly portable sized safety device is ideal for travelers, timeshares, renters, dorms, hostels, or anyone looking for a temporary lock for a door.
The Add-a-Lock installs quickly and easily without any tools. While it’s probably won’t prevent a police battering ram from breaking down your door (just what are you doing in that room anyway?) it will provide an extra piece of security if faced with a flimsy lock.
