Question: Do we need any tools such as drills etc. for its installation?
Document: I searched for months for some way to secure an outward swinging door. I was unable to find anything that actually worked except this item. Very, very easy to install. Basically, you just have to drill the two 5/16 holes in the door and the rest is just screwing it together. Once installed, you realize that they will need  two truck to rip out your door. They are definitely not getting in from the outside.
Expensive, but I think that it was worth it.
Answer: no
