Hyper Tough Steel Privacy Chain Door Guard, Oil Rubbed Brass Finish

I love that these are "old school," still available, and easy to install. I purchased them for an acquaintance to quickly add extra security to the doors on a house she had recently purchased. All doors had obvious signs of someone tapering with them, trying to break-in while it was on the market for sale. Yes, we're sure they're not 100% foolproof but a criminal will definitely make more noise trying to enter. These chains seem well made, heavy %26 sturdy. Nevertheless, there are also other locks on the doors plus we're installing fencing, motion sensor lights, etc.
