THE HALL PASS - by Sparrows
Put away your credit card, you won't need it anymore for shimming locked doors. The Hall Pass is a cool looking stainless steel shim that is used to shim spring latch lock mechanisms such as those used in common knobsets and night latches. Won't work with deadbolts but you already knew that, right?
Fits nicely right in your wallet, or a shirt pocket, or just about anywhere you could put a credit card.
