This “stand alone” home security facility can increase the security level of your home's most vulnerable and most common burglary point! Most thieves simply kick the front door on the side where the door handle and latch are located, because they know that most deadlocks are fixed by a common 3⁄4"by 6" pine board. Pine is a kind of "soft" wood. When the pressure is applied along the texture of the pine, the pine is easy to split, and the pine texture is always in the vertical direction. Fixed on the floor, it has strong resistance to the front door and can be destroyed by "kicking in". When the latch fails, it will still try to keep the intruder away from your home. The bottom plate is 7/16" in height and requires at least one 1/2" of the space between the bottom and the floor (the door is locked by the night lock base) to the floor, providing a strong resistance to the front door. Being "kicked" destroyed. When the latch fails, the door support barrier still keeps the intruder away from your home.
