National Mfg N183-590 Brass Door Chain 5 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N183-590 is a brass door chain fastener designed to provide a secondary layer of security at entry doors. The chain allows a door to be opened partially without fully unlatching, letting an occupant verify a visitor before granting full access. This is an economical, straightforward hardware solution suited for residential installations including single-family homes and apartment units. Sold in a pack of five, this product is well suited for property managers, general contractors, or locksmiths outfitting multiple units at once.

The N183-590 is appropriate for standard interior-face door installations in residential settings. Typical applications include apartment entry doors, hotel or motel room doors, and residential front or rear entry doors where a partial-open security stop is required. The carded retail packaging makes it convenient for both professional procurement and individual unit service calls.
