Answer This Question
A: 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.

A: 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.

Q:Can the guard be placed vertically instead of horizontally?

Answer This Question
A: 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
A: 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.

GARBAGE
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.

The chain guard was easy to install, except that one screw head was bent inward all around thus unable to put screwdriver on it so one screw is unusable. I will have to go back to Home Depot to try and get a replacement screw. Otherwise, so far so good.
This chain door guard is constructed of a steel chain, diecast housing, plate and keeper, and it comes in brass-plated finish. This lock engages by allowing the bolt to slide into the keyed mechanism to lock, and it uses a B1 keyway, ILCO (1098M). This chain door lock allows a door to open slightly for safe viewing and ventilation. Installation of this lock placed out of children's reach will help prevent them from opening a door themselves to enter or exit into dangerous areas. All installation fasteners are included, and it can be used on a variety of door types, on or beside the door casing.

This swing bar door guard will increase peace of mind when answering the door by allowing the door to be cracked open slightly for viewing. When engaged, a ball on the keeper interlocks with the bar lock and prevents an intruder from pushing their way through. Although a standard swing bar door guard can add great security to your home, condo, apartment/flat, or hotel room, there has been some concern over the wide availability of emergency release tools, which are meant to release swing bar door guards in cases of emergency. We have improved upon the standard door guard design and added an innovative backup thumb turn security lock that blocks the release tool from disengaging the door guard latch. In cases of emergency, hotel security or emergency crews can pop the thumb turn off of the unit by applying approximately 100 lb. of force to the door. (Note that 100 lbs. of force is much greater than a simple kick in, so the emergency release feature does not compromise your security). Additionally, after the thumb turn lock breaks away, the unit still operates as a traditional swing bar door lock and a specially designed anti-Lockout emergency access tool is required to swing the door guard out of place. To help prevent forced entry into your home, it is always a good idea to engage the backup thumb turn lock whenever you are not actively using your door. Defender Security by Prime-Line offers a full line of security hardware designed to protect your home and loved ones.
