Defender Security U Door Reinforcement Lock (Satin Nickel) EXPIRED

This price is less than the 150+ TU Prime Day deal for it

Or... Two for $7.50 each [amazon.com].... in White or Satin Nicklel... I like the white ones that will match a lot of doors. For white, there is an additional $1 coupon on page, making $7 each...

When using these, you really need to use longer screws and anchor into something more substantial than the typical 3/4" wood door frame.

Behind every factory door frame in a residential home wall are typically two wall studs together (king and cripple). You want to use three 3 inch or longer wood screws and anchor into those studs through the 3 vertically aligned holes in the lock. The 4th hole that is closest to the room and because that hole will be missing the wall studs, you can use the supplied shorter screw to get started. Pre-drill all holes and wax the screws or at least use some bar or dish soap on the screws to make them go in easier.

PS: While you are at it, remove a screw or two from each hinge closest to the center of the frame and install some longer screws there as well. Over the years, I have seen enough vandalized doors to know the weaknesses.

PPS: These work only on in-swing doors that are quite typical with additional exterior storm doors... If your door swings out, like some front housing doors do, these will be of no use.

Sure it will be. Make sure the robber can't escape after they broken in lol.

Fakespot D, but only $7 and home depot also carries it so maybe it will surprise me.

Bought these last year for $12 so good deal. Wish I had seen the white ones before. Not sure about the 800lb force, but I mostly have them so my kids and their little cousins can't get out on their own, especially with a backyard pool. Only problem is, their grandparents can't figure out how to get out either.

I'm all for safety, but this may also be a disadvantage when emergency personnel are trying to break into your home if there is a fire, medical emergency, etc.

Link to Home Depot?

I bought it during the prime day sale for $8.xx or something. Its pretty good. As mentioned in one of the post earlier, the provided screws are not good. User your own. Very good quality.

I bought this for my basement door. It's pretty solid and easy to install and use.

Great price. Missed this last time on Prime day and I regretted it. I ended up needing it so I got 2 from Home Depot at $19.99 each.

$1 coupon for 2 pack white (YMMV).

Good stuff if you live in an apt in a shady neighborhood. I use this and a pair of 100lbs dumbbells to secure the door at nights.
