National Hardware N183-590 V807 Door Chain Lock Brass Finish 1/2 in x 6 in Security Latch for Front Door Interior Safety Chain Lock for Residential Apartment Doors

I live in an apartment complex and wanted some added security, when my wife and I are home, mainly when sleeping. Something about the maintenance guys, property manager, etc. having a key to get in makes me want to take an added measure. Some of the reviews said it could be easily broken, I have no idea what they are talking about. I grabbed the package it came and was immediately impressed by how much it weighs! If this is properly installed on the door, and preferably on a stud around the door frame, it is SOLID. I mean, this chain isn't a little flimsy chain, a lot thicker than I expected. The whole thing is very well made, a nice weight to it, fits in the slider perfectly, very secure when screwed in properly. and is incredibly cheap! P.S. - Drop a comment down below with any questions. I check for comments on my reviews regularly!

got this at a good price, for my house this is what we needed, an extra level of comfort, sure nothing is undefeatable, but this keeps the cat and parrot from opening door, he's a smart cookie and we have an old style handle lock, not a knob and I don't like knobs, I'd order more if I need in future, fast getting here too

Very easy to install. Holds strong to door and frame.

I purchased this product when my 3 year old started opening doors and going outside without waiting for an adult to escort him. This product works well for this purpose. We installed them high enough that he cannot yet reach them. We did, however need to place them further apart than was suggested on the instructions because we felt like at the recommended placement the door could open too far. We wanted to make sure that our son could not fit through the opening. My husband left the chain in place one day when I was at work. When I got home he was in bed so I reached through to try and slide the chain from the outside so I would not have to wake him. I was able to do this with little effort. So not great in terms of keeping out intruders, perfect for keeping toddlers contained.

Buena calidad
