About This Product

Secure your home or office doors with additional security with the U 9907 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 solid brass finish and a 6 inch, 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 inch. 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 inch (approx. 3 inch). The smaller chain-holder base measures 3/4 inch wide, and the wider chain lock keeper measures 3-5/16 inch long; both with a height of 2 inch.

    Answer This Question

    Not sure if it makes sense to put the “Slide Plate” near a window, (broken by intruders), through which their hands could fit through to un-slide the bolted chain.

      Thank you for your inquiry regarding this item from Prime-Line Products. Use your own discretion. The installation close to a window might allow access to it if window was broken.

          Can the guard be placed vertically instead of horizontally?
          ByMay 20, 2020
          2 Answers | 
          Answer This Question

          I have not used it vertical but it should work as long as the parts are placed close enough to each other so it can go on and off and the large opening on the end of the slot is on the top.

          By|May 21, 2020

          Thank you for your inquiry regarding this item from Prime-Line Products. it is not designed to be installed this way. I am not sure why you would want it installed vertically. Gravity / the weight of the chain would make the chain drop down the slot. It is a choice you would have to make. Use your own discretion.

            Does the installation differ depending on which way the door swings (in or out)?

                            I just purchased and installed this lock. My TWO year-old pulled the door open and broke it. One of the links bent like it was plastic. I'll be returning this.
