Door Reinforcement Lock Withstands 800lbs of Force - Silver Extra Child Proof Door Lock with 8 Screws Prevents Unauthorized Entry,Add a Door Security Lock for Home Safety & Privacy

These add-on security devices are easy to operate if installed properly. They are are well crafted and fabricated and tough. Finish is also tough compared to the average. Appearance after installation is noticeable but all such devices are. These particular devices are the most effective that my research uncovered. You must decide what device is best suited to your situation. ( Obviously these are practically useless for a glass panel door.) I am quite satisfied with my selection and installad result. This device provides security against “kick assault” that is beyond the failure resistance of the door capacity, except steel doors in steel frames. If you have a steel door and frame and want more security than the latch and locking device, then you must carefully study the clearance (gap between door edge and frame) since there is no easy solution to locally increasing that gap to fit the plate that must be installed in the gap. If you have a wood frame with a wood door (or a modern composite door) the same gap fit requirements apply. If the gap is too narrow for the plate is very snug, or the plate won’t enter the gap, then chiseling into the frame to sink the plate into the frame. There must be adequate clearance for the door will open and close without hitting or rubbing against the plate. The next step is to snugly arrange the mechanism into the gap with the dark pad is in lock position against the surface of the door face, and fit a space filler (wood sliver, shush kabob skewers, spoon handle, any convenient spacer) between the hing side of the new lock and the trim along the door frame and wall face. This step is crucial as you must determine where the exact location of the drill holes. The device will never exactly abut the door stop. With the door open you can accurately judge where the plate must be located which determines the critical location of the three-in-a-row holes, since you cannot redrill those holes without filling the miss-located holes, then redrilling a very small distance away, including drilling largely into the plug wedged into the mislocated holes. Difficult and annoying fix. I chose 2.5 inch #8 coated deck screws to deeply anchor into the framing stud, and the larger diameter ( from the supplied #6 screws to # 8) for added sheer capacity. My 2.5 inch screw selection was convenient since I had some on hand. If I had 3 inch at hand, I would have used them. If you decide on that choice, it requires using a countersink to enlarge the tapered holes in the plate so that the heads of the #8 screws do not stand above the lock plate. This does require additional work and precision. Once these requirements are met, the lock can be finally installed. All of these recommendations are intended for do-it-yourself installation. If you want to hire an outside installer, you are at the mercy of the installer’s expertise. I truly wish you well in utilizing one of these devices for your additional comfort with your added security.

The media could not be loaded. I purchased this same lock after I saw it at my friends house. Its very affordable and the quality of the product is great. Its very easy to open from inside because of the clear instructions provided itself in the lock. None can break as its very strong lock. Its very easy to install with the screws provided in the box. Not needed heavy equipment or drills. I used screw driver and it was perfect. It fits perfectly on almost everydoor. Please watch videos in instructions to see on how to fit. Also its appearance is simple and great.I would recommend this product for child lock as well.

Easy to install within minutes and works great. I got them once my kids learned how to open doors through the child safely knob covers for the front and garage door. It gives me a great since of security knowing these keep the door closed if/when unlocked and also just a nice security measure for my home.

Clear instructions. Easy to install. Holds securely. I chose to use screws longer than the ones that came with the product. It fit well without me having to use a chisel. My wife has arthritis in her hands, and she has enough hand strength to pull it open from the locked position. It works.

Super easy to install and use, perfect way to keep our toddler from opening the front door.

These locks were easy to install (my husband did the installation). They are nice looking on our doors, and are very secure! Much better and safer than just a deadbolt. They are a little difficult to unlock at 1st, but with a little practice, they have become much easier to unlock now. great value for the price. They come in black or white. We have dark brown interior doors, so we chose the black. Very pleased.

Very easy to install and my door is locked solid. I will be buying another now that I know it works well.

My toddler has recently learned how to open all the doors in the house, so I quickly learned I needed to find an affordable way to lock it as she’s also figured out how the locks work. This was an easy installation, used a drill and a pencil really, everything else you need comes in the box. It’s easy to maneuver and seems pretty durable. Definitely makes it hard for my toddler to escape.

I recently purchased this door lock from Amazon and I'm incredibly impressed. The installation process was a breeze, even for someone like me who isn't particularly handy. The instructions were clear and concise, and the included tools made the job a lot easier.Once installed, the lock feels sturdy and secure. I've been using it for a few weeks now and haven't had any issues. The lock mechanism is smooth and quiet, and it's given me peace of mind knowing that my home is better protected.

The media could not be loaded. This is great choice for those seeking a secure, durable, and reliable lock. It is Super easy to install. Highly recommend.

Good for protecting

I’m a landlady and already have a key turn lock door handle on my bedroom but this brilliant lock gives me extra peace of mind when I go to bed , And especially when I’m home alone at weekends , as my neibour got burgled a while ago by 4 men climbing onto the conservatory and broke through the window and into the hallway and all the other bedrooms . This lock gives me extra safety and time to call for police help should I ever need it . I love the design and easy installation by myself and it’s SO easy to use .

Very easy to install and it's a solid lock. I think you'll break the door before you'll break the lock. Shouldn't take more than 10 minutes to fit.
