Overview
Upgrade your security with the National Door Lock. A safety precaution, it allows you to partially open your door and visually see who is at your door without allowing full access inside your home. The steel chain door lock can also be utilized as an out-of-reach door security measure that will restrict outdoor access to children without the assistance from an adult. Simply screw the two security panels onto your door and frame and slide the chain link lock into its track. National Mfg. Stl Chain Door Fastener N183590:.Specifications
