Door Jammer Portable Entrance Lock

Compact extra security for doors at home or on the go

The Door Jammer Portable Entrance Lock is a compact, mechanical security device designed to add a strong, secondary barrier to inward-opening doors. Constructed from durable metal with a stable, anti-slip foot, it works by transferring force from the door to the floor, helping to resist forced entry attempts. Lightweight and easy to store, it fits most standard interior and hotel room doors with a thickness of 35-50 mm.

To use, simply slide the jammer's front plate under the bottom edge of the closed door, then adjust and secure the foot so it is firmly braced against the floor. When pressure is applied from the outside, the device pushes the door slightly upward and locks itself more firmly in place. This design helps provide additional resistance even if the existing door lock is weak or compromised. The included rubber pad and heightening pad help improve grip and fit on various floor types, including hardwood, tile, marble, and low-pile carpet. When not in use, store everything in the included storage bag for travel or daily carry.
