Rated 4.3 out of 5 by 10 reviewers.
Rated 1 out of 5 by 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. July 30, 2014
Rated 4 out of 5 by brass chain door guard I am not sure i can write 50 characters concerning a door lock but my visit was good at the store with assistance as needed by associates i selected the door lock by myself with no assistance however the store associates did assist as needed. the lock works fine and i am not certain how it compares to pricing with your competitors HD and all stores should be concerned with the service we receive when shopping and the product should be of the last question since most people review product prior to shopping on products that are of much importance. A door lock is not that important except for the price. i usually receive the assistance needed in this store and the associates are nice. They do not run when they see you coming down an aisle. I usually have a little trouble getting the assistance needed in paint due to lack of associates however it is not as bad as some stores. There is usually at least one associate and if they are mixing they can only wait on one customer at a time. September 15, 2014
Rated 4 out of 5 by Great Product, Old Design The quality and value of this product is good. I did not see anything else on the shelf that would have been what I would have wanted, so this had to do the mediocre job. This Company or any other would need to redesign these so that the latch could have more sturdiness and security with hollow metal doors. Most developers install these kind of doors so Engineers get busy and get out of the stone age. May 6, 2014
Rated 4 out of 5 by You may want different screws I got this when my husband deployed for a little bit of extra security since I'm essentially living alone while he's gone. It's held up well, but be aware that it only includes wood screws for installation, and they're not long enough to go all the way through standard trim. My dad opened the door without realizing the chain was on, and the trim started to pop right out of the wall, the chain along with it; no damage done, but if it was someone trying to force their way in, the trim would have come all the way off with very little effort. I now have it installed with the longest wood screws I could find so I know they go all the way into the stud, and it seems extremely secure. I also installed the slide with sheet metal screws because I have a steel door, and woods screws can potentially rip out of metal. April 16, 2014
Rated 5 out of 5 by Nice Quality Very sturdy product. Great price. I have no complaints April 8, 2014
