National Marker N199679 Brass Door Security Guard

Product Description

The NATIONAL MARKER N199679 is a polished brass decorative door security guard designed for residential use in houses and apartments. It allows partial opening of the door for ventilation or viewing while resisting forced entry attempts. The unit cannot be unlocked from the outside, providing a reliable one-sided security function. Installation is straightforward, and the guard is engineered to prevent damage to the door and trim during normal opening and closing cycles. Sold as one unit per pack, this guard serves a dual purpose as both a security device and a decorative accent.

This door security guard is suited for residential interior and entry door applications including single-family homes and multi-unit apartment buildings. It is typically installed on hinged interior-facing door edges where controlled access and partial ventilation are needed without fully opening the door to an unknown visitor. The decorative polished brass finish complements standard residential door hardware.

Installation Notes

Installation is typically performed by a general contractor, handyman, or knowledgeable DIYer using basic hand tools such as a screwdriver or drill. Ensure the door is fully closed and stable before marking and fastening mounting points. Follow local building codes for residential door hardware where applicable.
