National Mfg N199-679 Door Security Guard Bright Brass 5PK

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N199-679 is a bright brass door security guard designed to increase entry-point security on both wood and metal doors. The guard mounts to the door and frame to allow the door to open slightly for ventilation or viewing while physically resisting forced entry attempts. It cannot be disengaged from the outside, which eliminates a common vulnerability at secondary and primary entry points. Installation is straightforward and intended for locksmiths, carpenters, or general contractors working on residential security upgrades. This package contains 5 guards, making it practical for multi-door or multi-unit applications.

This door security guard is suited for residential entry doors, apartment doors, and hotel or motel room doors where occupant safety is a priority. The bright brass finish integrates with standard residential door hardware. The dual-purpose function — partial door opening for airflow or visual identification combined with forced-entry resistance — makes it a common specification in property management and multi-family residential installations. The unit ships carded and is sold in a pack of 5.

Installation Notes

Installation is typically performed by a locksmith, carpenter, or qualified handyman using standard hand tools. Before installation, ensure the door and frame are structurally sound and free of rot or damage that could compromise fastener holding strength. Follow local building codes regarding egress hardware requirements, particularly in rental or multi-family occupancy settings. Do not install in a way that obstructs required emergency egress.
