National Mfg N274-407 Satin Chrome Door Chain Fastener 5pk

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N274-407 is a satin chrome door chain fastener designed to allow a door to open partially while maintaining a secondary security barrier. The chain and mounting hardware install on the interior face of an entry door, limiting how far the door can swing open without fully unlatching. This type of hardware is commonly installed by locksmiths, general contractors, and property maintenance professionals. The satin chrome finish provides a neutral, low-glare appearance that blends with standard residential door hardware. Each package contains 5 units, making it practical for multi-unit or multi-door installations.

This door chain fastener is suited for residential interior and exterior doors where a partial-open security stop is needed. Common applications include apartment entry doors, hotel room doors, and residential front or back doors. The carded retail packaging format is standard for hardware distribution to both trade and retail channels. With 5 units per package, a single order covers multiple doors in a building or unit.

Mount the chain receiver plate to the door frame and the chain slide to the door face using the supplied fasteners, ensuring both surfaces are flat and solid wood or metal backing is present. No special tools beyond a hand drill and screwdriver are required. Verify the door frame and door edge are free of warping before installation to ensure proper chain engagement.
