Prime-Line U 11126 Door Reinforcement Lock – Add Extra, High Security to your Home and Prevent Unauthorized Entry – 3 In. Stop, Aluminum Construction, Bronze (Single Pack)

The defender door locks are easy to install and provide a secure indoor locking function. What I really like is the ease of installation. I pulled out the Dewalt impact screw driver and my first one was done in a couple minutes. I did not have to pre-drill but probably a good idea to do if you do not have a impact screw driver. I like this so much I bought another one for a different door. The second one I installed required me to cut out a door frame notch for it to mount flush and work properly. Without the notch it was hitting the door when it closed. This took about 10 minutes with a chisel to do. They both work smoothly and fast to engage and disengage. They work well not only securing the door but providing that extra layer of protection along with the deadbolt. It's also good to prevent those smart kiddos that figure out how to unlock and open the front door at age 3. Pros: Easy install (on most doors) Good value Secure and strong Attractive and a small space footprint Multiple finishes to pick from Helps child proof the house Cons: Have to get use to how to open and close these Some doors may require a little chiseling for mounting You can accidently lock someone out (as with all indoor only locks)

I cannot praise this lock enough. Quick summary of all its advantages: + This lock can be installed, even if your frame/mold is not flush with your door, which is the case in my house. It took me forever to find a lock that was suitable for this situation. + If you get SPAX screws and you have a wooden door frame, you do not need a drill to install this lock. You can just screw it right in. That is what I did and it was easy. + in general, this is very easy to install and does not take long. Although, if your frame/mold is not flush with your door, it is a bit tricky to get it positioned right. Perhaps stick it to the frame with double sided tape, close the door, and see if it easily closes; then mark the position of the holes with a pen. + It looks good + Super easy to open and close + If you use 3" screws, they go past the frame into the wall, which means that people won't be able to kick in the door by kicking against the frame + I don't see how this lock could be opened from the outside, it seems very secure. I feel so much better knowing that, even if my main lock gets picked, this one will still keep the door shut. Things to be aware of: + You cannot open the door at all when this lock is closed. If you want to open the door even just a little, you have to open the lock. That is exactly what I wanted but I know others want a lock where they can leave it locked and still open the door. + There needs to be a little bit of space between your door and the frame. Otherwise, the lock will not fit in between.

Our children had reached the age where they can open child-lock doors, and after discovering my 2 year old daughter has an exploratory vibe and had gone downstairs into the basement unnoticed, I decided to try one of these door locks. Note that this is interior to the house, so it's not so much to prevent break-in, just control access. Note that it's important to always have an egress path from where they are installed in a locked position in case of emergency. I would prefer a different design that has egress options on both sides of a door if you're trying to train a child to stay in their bedroom. I went with this model because the finish matched the rubbed oil bronze finish of the door hinges and door knob. After installation, the door security lock fits nicely with the decor. The door security kit comes with short screws that go into the door jamb that provide less strength, and longer 3" screws that should anchor to the stud frame around doors. There is more potential for stripping the screws if you only use the short ones that go into the door frame instead to the jamb. This is because the short screws would only anchor to the door frame that is often a type of decorative molding that doesn't have the structural strength of 2x4" studs (it doesn't take much force to deform the material). I decided that even if installed indoors, I wanted the door lock to be secure so I decided to use the longer 3" screws. The installation was easy but not without incident. Note in the picture with the drill bit and screw side by side that they are about the same length. When you put the drill bit in the drill, you have to sacrifice some length because the shaft sits in the drill chuck. The common drill bit length that you get in a normal drill bit set will not pre-drill the entire length of the longer 3” screw. So I pre-drilled as much as the shaft would allow me to drill, and used the lowest setting on the impact driver to push the screw into the hole. I had less than 1/2" remaining and it would not progress any further on the impact driver’s lower settings. I didn't have a longer drill bit length so what did I decide to do? I cranked the impact driver to 3 and after about half the distance I snapped the screw head clean off. Kraggle! Now I had a headless screw that was majorly stuck and the remaining screw was only protruding about 1/4" from the door frame. To remedy this, I used IRWIN Visegrip Quick Adjusting GrooveLock 10-in Electrical V-jaw Pliers to pinch the small remaining exposed screw length and spent about 15 minutes de-threading the screw from the door jamb. I needed the longer pliers length to get the torque to unscrew the threads, but when the pliers are that big, I still ended up deforming the door frame molding a little bit. I went to Lowe's and looked for a DEWALT 1/8-in 6-in Black and Gold Coated Hss Twist Drill Bit. Lowe’s was out of stock, but they had a 12 inch length drill bit in stock so I just decided to go with that. I would have preferred the smaller drill bit length but the door opening width still gives enough room with the 12 inch long drill bit to pre-drill the holes straight on. To ensure I didn't over drill the screw length, I placed a wrap of painters tape at the length on the drill bit to mark the screw length so I'd have no risk of over committing the hole and drilling through drywall just a few inches beyond the door jamb. Once I pre-drilled the correct length, I was able to use the impact driver on the lowest setting to drive the screws all the way into the door frame and jamb. Note with philips head screws, try to use the "fattest" impact driver bit that will still fit in the screw head. It's the best way to help prevent deforming the screw head from the bit slipping. In the end I had to borrow one 3" screw from a second kit that I had bought, though I could have gotten away with using two 3" screws on top and bottom and one small screw in the middle. Hopefully you read this making the same mistake! To open the door, you just have to pull out away from the door frame and then rotate to open. To close, you can simply rotate it back and it will snap into place, or you can pull out a little bit and you won't get the small "snap". All in all, I'm very happy with the end result, as now we have control of access to the basement to keep our little ones safe (and help keep the wife sane). It's easy to use and the wife loves it, so it's a win-win. Highly recommend if you want something to fit the house decor even though some people may consider it a little bit overkill.

Latch looks and operates nice. Screws are horrible. The heads broke off on two of them and I barely got them out of the door jam with a pair of vice grips.

Facil de instalar, Gran resistencia y cumple con las espectativas de asegurar la puerta.

Ótima qualidade e simples instalação

Funciona tal como dice la descripción.

Produto aparenta ter boa qualidade, é fácil de usar e de instalar

So simple, but INCREDIBLY TOUGH, AND EFFECTIVE. Way stronger than a deadbolt. I just put two on my back door. Took a picture. It took less than 1 minute each to install them. I unlocked the handle, and the deadbolt, and these two new locks don't let the door budge! Not even a mm. I'll be showing every guest how incredible they are. I just moved into this house, and this makes security a non issue. The noise it would take to try to break into this door, would give me way more than the 6 seconds it takes to load , and chamber my 12 gauge pump. :)
