(3) preparation steps were required to achieve the level of door security demonstrated in our video:
All are links in a chain. If any of them fail; the chain breaks and your doorway will be breached.
In this demo video…
First, we made sure the Door was in good structural shape.
In our demo, the door is a standard exterior residential metal skinned door.
Despite being approximately 8 years old, the door was determined to be in good structural shape.
If your door shows signs of warping or wood rot in the wooden core or around the hardware; we suggest you replace the door before investing in a Door Devil as we can’t provide the level of defense shown in the demo unless its on a door on which it is installed is structurally sound.
Second.. We upgraded the deadbolt from a cheap contractor Grade 3 to a quality GRADE 1 deadbolt.
Having a cheap deadbolt would have failed in 1-2 swings of the sledgehammer or kicks.
In our demo, we used a Schlage Grade 1 deadbolt.
