The best way to reinforce your frame is by adding a layer of steel to prevent them from splitting. This makes your door kick proof. Installation entails placing high-gauge steel over the door jamb and securing it with long screws. The screws should penetrate through to the wall studs on all sides of the doorway.
The best ways to secure a door from the inside is to use a door brace. They require no special door modification, are easy to install and easy to remove. They stop the door from being forced opened, and they also prevent the door from being opened if your locks have been unlocked (from a key, picking or lock bumping).
Typically, the screws in the plate are 1 inch (2.5 cm) long. By replacing them with 3 inches (7.6 cm) long screws, you will strengthen the lock and make it more resistant to force break-in.
The best way to secure your front door is to use deadbolt locks, which are the strongest type of lock, short of commercial-grade locks. Extra-long screws on strike plates also provide additional security. When you have multiple locks, remember to always lock all of them, especially the deadbolts.
Door strike plates reinforce the area of the door where a door latch will sit when the door is closed. They help the latch stay put, protect the door jamb from friction, and keep the door opening and closing smoothly. Door strike plates reinforce the area of the door where a door latch will sit when the door is closed.
You can reinforce the door by adding a high-security steel striker plate with four screws that penetrate deep into the stud framing plus longer screws to the hinges. This type of reinforced door is almost kick-proof.
Door security bars give a superior security measure compared to locks and other door security devices. Some models only weigh around a pound, yet can withstand up to 350 pounds of force. A high percentage of housebreakers prefer to burst in through the front door if possible.
Still, having longer screws isn't a guarantee that no one will be able to kick in your door. It might just take a bit longer for it to come apart. “Those longer screws go into the stud that's behind a door jamb, so instead of splitting that initial wood, it's in a deeper sub wood, so it's grabbing more,” Whipple said.
The first and best step to reinforce your front door is to simply replace the 1/2 inch screws with 3 1/2 inch screws. This is the very first thing all homeowners should do to strengthen the door's frame.
To penny lock a door you simply jam pennies between the door and the hinge from the outside, which prevents the door from opening from the inside. If done properly, the only solution is to remove the door from the hinge. While penny locking a door can work, it will only work with certain door jams.
The door bar sits in the door way and acts as a transition between your wooden floor and the floor in the next room. For example, it would cover the gap left between the wooden floor the adjacent floor, e.g. tiles, carpet, etc. You have a choice of style of door bar, depending upon your requirements.
Strike Plate
This is the plate the latch-tongue, or deadbolt-tongue will connect with. It should sit flush with the door jamb. Any passage or privacy set needs to have a strike plate for the door to latch. Additionally, deadbolts need a strike plate to properly lock.
Door latches are a type of mechanical hardware used to fasten doors and keep them shut. A door latch uses a fastener attached to two ordinarily separated surfaces, most often the door and the frame, to prevent the door from swinging while still allowing normal operation when the latch is released.
