## Questions & Answers

**Q: You show piocture of 6 plates and a door shield ? whats actually in ki?**
A: I just purchased this kit and I too had the question of why there are so many pieces before I received it. There is a total of 6 long skinny metal plates that all install on the door jam side. 3 on top of the other 3. Parts B-D-B fit on top of A-C-A and run the whole height of the door jam. Then there are 2 parts that go over the end of the door for reinforcement there. All screws are also suppliedI will try to attach 2 pictures that will better show how that product installs.

**Q: Why suddenly double the price?  When looking yesterday, price was ~$20.  Came to order today, & price is now ~$39.  Not worth it now unfortunately.**
A: I looked at the local home improvement stores, and when I bought mine, the store was almost1/2 what I paid here, but was worth it not to have to leave my home unlocked and unattended.  Now the store is 4 times what it was last year; I ASSUME  it's the "inflation " hitting everything!?!

**Q: My house lock has spacing of precut 4" spacing between the deadbolt and entry lock.  Will it work on this product?**
A: My daughters apartment was the same way, I had to cut a new hole above the precut holes in both pieces . I used a drill to make the starter hole then use a jigsaw to finish.Hope this helps

**Q: What is the distance between center-handle-latch to center-deadlock?**
A: The second picture in the listing shows all the specs.

    Solid design
  

*by C***I on Reviewed in the United States on 25 March 2024*

Works well. Extremely solid design. Easy enough to install and handled the issue I was having. Only minor complaint is make sure everything is lined up correctly. Having to take a bunch of pieces off to fix a misaligned hole can be frustrating.

### ⭐⭐⭐⭐⭐ 







  
  
    Solid product
  

*by A***Y on Reviewed in Canada on 14 December 2023*

Not too hard to install but be sure to shim your door frame to the studs before using long screws to attach everything. Feels like it should leave your door pretty kick resistant when coupled with something to reinforce the lock area of your door.

### ⭐⭐⭐⭐⭐ 







  
  
    Fantastic product!
  

*by N***. on Reviewed in the United States on 23 October 2022*

Pricing -Similar products are $100 or more so this is a steal! I was able to get two for less than the price of one! 5/5Packaging - Comes with more than is seen in the pictures (actually has two deadbolt/knob protectors.) Old school plastic packaging so definitely not hassle free, but I guess that's expected from a security company 5/5Design -The jamb parts are double layered which is interesting, but you quickly see why since if one layer fails then the second is still there. If you have double studs or a 4x4 then you'll quickly wish the kits came with at least a 4" drill bit since normal bits don't go far enough with makes you have to give extra effort in-order to get the screws in without stripping them. Other than that, setup is fairly simple so once you do one part, you'll breeze through the rest. The only confusing part was keeping up with all of the different screws for each part (instructions don't specifically say what goes with what.)The design itself is great. As with anything the more screws you add, the more strength it has, so the same applies here. It almost spans the entire length of the jamb & there's numerous 3" screws throughout. It has multiple options for regular locks as well as mortise locks. After setting everything up I gave the door a few shoulder shots, kicks & punches to test (I'm a big guy)... it didn't budge an inch! Not to mention both the steel & paint job are very high quality! 5/5Overall this is a surprisingly great product. The only thing missing is hinge protection which is a huge let down. Other than that it is easy to install & extremely sturdy. We'll see how it fairs against an actual break-in.5 out 5 stars
