Difficult Lock Upgrade

Upgrade To A More Difficult Lock For The Beer Can Puzzle
Our Beer Can puzzles are very popular and the standard lock that comes with them are sure to stump even a well seasoned problem solving puzzle enthusiast, but if you want to take the puzzle to the next level, make it more difficult or have someone who thinks they are a bit of a puzzle wizard then you can upgrade the beer can puzzle with this more difficult locking mechanism.
Please note:If upgrading the lock for the 4 pack Beer Can Puzzle we recommend you purchase 2 lock upgrades (if only one lock upgrade is purchased the puzzle will be locked with one regular locking rope and one upgraded lock as there are two locks on the 4 can puzzle). The single and double beer can puzzles only require the one lock upgrade to be purchased.
