Using one lock per window sufficient or should we use two on each window?

Asked by: LynGia

Fire exit window

Can this lock work on a fire exit window. Is it approved by the NYC Fire Department? Can it be easily unlocked without a key?
Asked by: julia
I don't know about FDNYC rules. They are easily removeable. A minute or less to install; a minute or less to remove.

White Vinyl Window Security Lock is rated 4.4 out of 5 by 36.
Rated 5 out of 5 by from Very easy to install The instructions for installation could be improved.

Rated 4 out of 5 by from This indeed a great product but you have to do it in irregular way to make that work PERFECTLY! You don't just clip both sides (left and right) to make it work. You clip (both units) in one side to make it works perfectly! ----------BOTH UNITS------- at one side! Vinyl windows just suck, you don't drill holes or do anything that harms the surface of the windows. I tried one at a side, I could still push the window up. When I just put both clips at one side, I think I have to break the window frame to make it open. Very secured. Try it if you had a set.

Rated 5 out of 5 by from Great product! This product does make me happy! I own 2 of these and am off to buy about 4 more....It looks better than a "stick" in the window (to block the window from sliding) and it is very secure. (truthfully i like the stick and this device together- they can see the stick from the street along with my electronic alarm sign and my beware of dogs sign.) By the way....any window left open no matter what device you use is a visual invitation for any burglar, i don't care if you have a 1000 dollar device installed, if a window is open it is not secure. Even if a window is closed it can be easily broken with a simple rock from your garden. BUT- if you are like me and want to slow down or make a burglar make a lot of noise to break a allows a better chance the thief will be slowed and at the very least make your home less attractive to break into. It also gives my dogs a chance to bark like mad and wake me up to handle the situation. My neighbor across the street chased off 2 burglars that broke into someones house side window, the noise alerted her and it scared them off. Anything you can do to slow down a criminal is go side good in my book.

Rated 1 out of 5 by from didn't work for me; burglar was able to slide window open I installed one on each of my new windows over a year ago. I left one of my bedroom windows slightly open for ventilation. It seems pretty secured when I tested it. However, I came home from work today and my place was burglarized. The burglar cut the screen on the window first and then was able to slide this device along the window tracks and gain access into the house (though the window that was left slightly open). The police told me that there are better options available and I'm researching now for alternatives. I hope that you'll have better luck securing your home and stay safe.

Rated 4 out of 5 by from GOOD SECURITY TECHNOLOGY Easy to install, even for a height and strength challenged senior woman. May even offer some protection against someone pushing in tilt-in windows, which is not mentioned as a protective factor.

Rated 5 out of 5 by from works great Just starting installing them and they seem to work great, easy to install. I thought the price was a bit high but then found that they are 2 per package, which was not stated on line.
