Prime-Line U 9912 Keyed Chain Door Guard, 3-1/4 In., Steel and Diecast Construction, Brite Brass-Plated Finish (Single Pack)

Good quality and gets the job done. I added this as an extra layer of protection and it works well. It was easy to install.

I bought this mainly as child-proofing in response to my 2 year old's knack for unlocking deadbolts and opening doors. My wife and I wanted something to bar the door without one of us needing to get to the door to let the other in each time one of us leaves. This chain lock was exactly what we needed. This thing is sturdy, solid metal and heavy. For a chain lock I feel this is as good as they come. Installation was 5 minutes, most difficult part was drilling holes into the metal sheathing on the door. The keyhole is located at the top of the lock and works by inserting your hand through the space in the door, (About 3-4 inch gap), and inserting the small padlock key. This is a bit tricky, as the lock is right up next to the wall. Once unlocked, gravity does the rest with the heavy chain dropping out the bottom of the lock to rest against the inside of the door. This comes with 2 padlock keys, and while I haven't had too much issue the cut does not appear to be a perfect fit. I have to work the key a second or two longer than I should to get it into the lock. Still, no real issues here, but would prefer a smoother cut key than this. I'm not sure I'd be able to make copies of these that would work in the lock. Overall, I'm pleased with the weight and security of this door chain and the functionality of being able to enter without needing to be let in.

Very happy with this lock it keeps my autistic 6yr old grandson from running into the street

The store like is pretty good quality my only complaint is the key seems to be the same even for different brands so that's not the most secure in my opinion.

This is a beautiful thing. My wife walked out 4 months ago. God listened to my prayers. So did this company. Looks like it’s for “while at home use” install it right, and you can lock & unlock from outside. Let’s face it. It’s only to keep honest folks out and make someone with a key to the house think you’re home. Exactly what I needed!

When you leave an apartment for the day, you usually have no way to use a chain for that little extra security, especially if you live in a building where they have your key. This is a great solution as you can lock the chain and reopen it from the outside. It is very solid and I had a worker install it using larger and better screws. You can install it yourself but I do suggest using proper largest possible screws for your molding type. Measure the height you want it as well as the clearance and distance from the chain to the lock before you install it of course. Very clever that the change has a place to put the catch if you are in and not using it. You can use this from the inside keeping it locked and using the other side of the chain to latch and unlatch. Good solution.

Extra security, no way to bypass it unless you break the door jam. That noise would be heard by your neighs or you if you’re inside.

This bronze latch is a nice item and very hefty. The only issue I have with this is that the key doesn't turn back to it's original place after releasing the chain, so in order to replace the chain and have it connect is to turn the key back myself and sometimes I have to hold the chain in at the same time. I think this was defective unit to start with. I bought three white sets and all of them work as described.

Ótima qualidade, faz jus ao preço veio bem embalado entrava super rápido

I like it because it gives me a little added security.

Very good quality door chain, good fit and easy to install! Great safety features and durability and good value for money

Have owned this for a few years now, and it works extremely well. Easy to install, and definitely worth the price.

Good construction, looks solid
