National Mfg N335-984 Door Security Guard Satin Nickel

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N335-984 is a satin nickel door security guard designed to increase entry-door security on wood or metal doors. The guard mounts to the door and frame, allowing the door to open a few inches for ventilation or visual identification of a visitor while resisting forced entry attempts. Once engaged, it cannot be released from the outside, making it a reliable secondary security layer at residential entry points. Installation is straightforward and does not require specialized tools. The unit ships in a visual pac with a package quantity of five.

This door security guard is suited for residential and light commercial applications where a primary lock needs supplemental protection. It works on inward-swinging wood or metal doors and is a common addition to apartment entryways, hotel rooms, and single-family residential exterior doors. The satin nickel finish coordinates with standard interior and exterior hardware sets. With a package quantity of five, the N335-984 is practical for multi-unit installs or contractor stocking.
