Home Security Door Lock, 2 Pack Childproof Door Reinforcement Lock with 3 Inch Stop Withstand 800 lbs for Top Front Inward Swinging Door, Upgrade Flip High Night Lock to Defend Your Home Kids

Nifty design and a nice surprise.
Yes, I’m impressed. Very impressed. After seeing so many kluge designs, this was like a breath of fresh air. I began by ordering the two-pack, not knowing if these were junk or not. Well, they aren’t junk. Actually, these nifty devices are terrific. They are relatively discreet and actually look nice. They are an effective, yet simple design that is easy to install. And I feel a heck of a lot safer now after installing them. Just note that no lock is burglar-proof, but these locks (along with reinforcing the frame, strike plates and hinges) will give one time to react. And if you are lucky enough to live in a free state, it will give one time to get your weapon of choice. After using two of these, I quickly ordered another two-pack kit. I’ve installed one on my front door, one on the outside side garage door, one on the garage door leading into the house, and then one on my bedroom door. My rear door is a French Door, so I’ll have to go with something else.The only caveat I can see are the supplied screws. They look to be #8 x 1-7/8” long. I highly recommend you do NOT use these, because they don’t look to be strong and are way too short. It’s okay to use one of these supplied screws (even the shorter screw) in the alignment slot. But once you are properly aligned and know you can easily flip the latch to lock and flip it to unlock, go out and buy #9 or #10 screws at least 3” long (I used #10 x 3” long torx-head).I also think that on the front door, it wouldn’t hurt to use two of these locks (one above and one below your dead-bolt). Matter-of-fact, I’ve just order another lock to do just that. My front door is such that I think one swift kick would have shattered the 3/4” soft wood frame. That is the reason I reinforced every swing-in door and frame.Besides the supplied screws, is there anything else I don’t like? Not really, but I wish I knew what type of alloy and tempered aluminum these were made out of (like 6061-T6 or whatever). I also am not sure how good their spring is (I’ve read that a couple of people have had trouble with the spring breaking). I’ll just have to wait and see how these springs stand the test of time, but they do have a 5-year warranty, so I should be good.The fact is, these locks were thoughtfully, yet simply designed, look nice, and I rate them highly. They also seem very strong (don’t know about their 800 lb. force claim, but I don’t really doubt it). Also notice that 90% of over 130 reviews rated this lock 4 or 5 stars, which is quite amazing. Therefore, I will easily give these a 9 out of 10, or a 5-star rating.

Proper installation is important!!!
My wife said that my toddlers used to constantly open the front and garage doors and wander off while I was at work, but this latch solved the problem completely. Once installed high enough, it’s truly childproof and gives us peace of mind.Installation was straightforward, but you do need to make sure it’s aligned properly for smooth function. On my wooden front door frame, I used a wood chisel to get a perfect fit. For the metal side of my garage door, I had to use an impact driver bit to drill through, which worked fine.The latch itself feels sturdy and well-made, with solid metal construction. The kit even includes two screw sizes (medium and long) to fit different door types. So far, my toddlers haven’t been able to budge it.Overall, I’m very satisfied with this purchase and would definitely buy it again for future doors.

Recently started living alone and had this installed. A friend tried forcing this open with it unlocked/latched. Could not force it open. Instantly makes you feel more secure when alone.
