A pocket-sized steel lock that adds a second barrier to any inward-opening door in seconds, no drilling or tools. Wedge it into the strike and the door cannot be opened from outside even with a key — peace of mind in hotels, Airbnbs, dorms and shared rentals. Travel-friendly, weighs almost nothing, and works on standard lever and knob doors worldwide. The cheapest insurance a solo traveler or renter can carry.
It is designed for inward-opening doors (the common hotel and rental type); check the door swing before relying on it.
No tools or marks — it removes cleanly and leaves the door unchanged.
