Add an extra layer of entry door security with the Prime-Line U 10304 Chain Door Guard Lock. Designed for residential and light commercial applications, this classic chain-style security device allows doors to open partially for visitor identification and ventilation while helping restrict unwanted entry. It is an effective supplemental security measure for apartments, homes, offices, and other interior entryways. Constructed from durable extruded brass with an attractive bronze finish, this door guard is built for long-lasting performance while complementing a variety of décor styles. The 6 in. welded steel chain with 8 links provides dependable strength and controlled door opening when engaged. Its versatile design can be installed over or alongside the door casing, making it suitable for a wide range of door configurations. For added household safety, the lock can be mounted higher on the door to help limit access by young children. Installation is quick and straightforward with the included fasteners, making it an easy DIY security upgrade. Compare dimensions and installation requirements before purchasing to ensure proper fit.
From the Manufacturer
This chain door guard is constructed of extruded brass and comes in a satin nickel plated finish. It features a 6-inch long, 8-link welded steel chain and all installation fasteners necessary for complete install. When this chain door guard is fully assembled and engaged from base to keeper, the chain will extend to 4-5/8 inches. To determine the maximum distance it secures a door for safe viewing or ventilation, subtract the thickness of the door from 4-5/8 inches (approx. 3-inches). It can be used on a variety of door types and over, or beside door casing. The smaller chain-holder base measures 3/4 inches wide, and the wider chain lock keeper measures 3-5/16 long; both with a height of 2-inches. This chain door guard also works great as a child-safe security device which can help prevent little ones from fully opening doors and entering or exiting into dangerous areas. See model number U 10305 for classic bronze, U 9909 for satin chrome, S 4298 for chrome, U 9913 antique brass and U 9907 for brass.
