National Marker N335984 Satin Nickel Door Security Guard

Product Description

The NATIONAL MARKER N335984 is a satin nickel decorative door security guard designed to add a layer of protection to residential and apartment entry doors. The guard allows the door to open partially, giving occupants a way to check visitors or allow ventilation without fully releasing the latch. When engaged, the guard resists forced entry and cannot be released from the outside. The hardware is designed to minimize contact damage to the door and door trim during everyday open and close cycles. Sold as one unit per pack.

This door security guard is suited for residential installations including single-family homes and apartment units. It mounts to standard interior door frames and provides both a functional security barrier and a decorative satin nickel finish that blends with common interior door hardware. It is a practical addition for any door where controlled partial access is needed without fully compromising entry security.
