PRODUCT DESCRIPTION Secure your home or office doors with additional security with the U 10304 Chain Door Guard. This door chain lock is a security locking device for doors, allowing a door to be slightly opened to allow safe viewing and ventilation. It can also be placed out of reach of children, high on a door, so they cannot open the door themselves and enter or exit into dangerous areas. This chain door guard is constructed of extruded brass with a satin nickel plated finish and a 6”, 8-link welded steel chain. It’s strong and durable, sure to last, and installation is quick and easy. All installation fasteners are included, and it can be used on a variety of door types and can be placed over or beside door casing. When this chain door guard is fully assembled, and engaged from base to keeper, the chain will extend to 4-5/8”. To determine the maximum distance the chain door guard secures a door for safe viewing or ventilation, subtract the thickness of the door from 4-5/8” (approx. 3”). The smaller chain-holder base measures ¾” wide, and the wider chain lock keeper measures 3-5/16” long; both with a height of 2”. 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.

Secure
Easy to install. Forgot it was locked, swung the door open, the latch caught it and chain didn’t break. The coating does rub off and the chain does leave a line where it hangs but I don’t mind.

I did the installation recently and am so amazed at the sturdiness. Will buy more

Buena calidad y resistencia
Por el momento está bien. No ha perdido su color y ha aguantado cuando entramos a casa sin saber que está puesta y se pone aprueba su resistencia. Fácil de instalar.

Be careful if a replacement
Wanted to replace old brass chain guard. This one is a bit smaller and holes did not line up with old standard.

Handy little door lock
This door chain came in on time and exactly as described. I purchased it as a secondary lock for my back door and it works great to prevent my landlord from entering my unit unannounced. It is definitely not strong enough to be used a regular lock if you're using it to really keep people out. But if you are purchasing this for a bedroom door, or for reasons like I am, then it is fantastic.
