Buy Three Power Wedges
The Power Wedge is a safe, reliable and easy-to-use, floor-mounted, locking system that is not accessible from the outside. It is designed for interior and exterior solid core doors from the front door to the bathroom and to the bedroom. The Power Wedge instantly turns any room in your home into a safe room until police arrive.
Unlike typical deadbolts and chain locks that are attached to the weaker door jamb with small screws, the stainless steel Power Wedge is anchored with large stainless steel screws that use the strength of your floor to withstand tremendous force.
