What is a Door Reinforcement Kit?

A door reinforcement kit is a smart way to reinforce a door. Standard exterior and interior doors are designed to simply be entry points and do not provide as much security as you may think. The purpose of any door reinforcement is to improve that security, by either bracing the door or replacing components around the door.

The latch plate is one of the easiest ways to reinforce a door. Replacing this standard component is cheap and fast. There are many things to consider when upgrading a latch plate, such as:

  • Latch plate size – the size of the latch plate determines how any force on the latch is distributed. The larger the plate, the better. Once it gets a certain length, the distributed force trails off, and length matters less. If a plate spans multiple latches (such as the doorknob latch and the deadbolt) it will be even stronger.
  • Length of screws used – Longer screws hold the latch plate on better than short screws.
  • The number of attachment points – The more points a latch plate is attached with, the stronger it will be. A standard door latch strike is only attached with two screws.

A door reinforcement kit is superior to a door brace in that the door being reinforced is still operational. When you use a brace system to reinforce a door, you must do so from the inside.

Some reinforcement kits include bracing for other components of the door, and not just the latch plates. While the latch plate is typically the weak spot and the target for a break-in when it is reinforced other points of the door become the new weak spot.

If an intruder cannot kick in a door due to a reinforced latch, they kick a few more times with enough force and they can kick the deadbolt out of the door. This is why some kits also reinforce the door side of the latches.

If an intruder cannot kick in a door on the handle side, they can kick the hinges off the door if they are large and strong enough. This is why some kits reinforce the hinges as well.

The best-tested kit we installed uses all of these reinforcement points to make a door impossible to get through… unless, of course, you have the key.

How to Install a Door Reinforcement Kit

Depending on the kit, installing your door reinforcement can be time-consuming, tough, or even require specialty tools. This affected consideration for our picks, since installing a door reinforcement kit shouldn’t be as hard as getting through a reinforced door.

Most door reinforcement kits include a latch plate (at least) and lengthier screws to attach the latch plate. These kits will require some run-of-the-mill tools including:

  • Screwdriver– Most kits include Phillips head screws, although some kits may use security screws.
  • Drill– A drill can cut down on the installation time and prevent issues with the frame.
  • Drill Bits – A pilot hole where additional screws are being placed can prevent a headache.

If you are having trouble getting a reinforcement kit to fit, you may also need to consider using a:

  • Sanding Block– On doors that are a tight fit, you may need to add some clearance to add a kit.
  • Reciprocating Saw / Dremel Tool / Oscillating Saw– Some doors are just stubborn and require a lot of modification to add reinforcement bracing. Any of these tools you should have handy can quickly remove more material than a sanding block.

Installation on our best-tested kit came out under 30 minutes for the entire installation. We are not carpenters or handymen for a living, but the installation is pretty straightforward.

Who Needs a Door Reinforcement Kit?

Anyone who lives behind a door can benefit from better door security. A door reinforcement kit is the best way to do this for a home or bug out location. This is because the door is still reinforced while you are away.

If you rent or live in an apartment, you may not be able to install a reinforcement kit. That is where a portable or temporary solution can work. It may only reinforce a door while you are behind it, but bracing a door is a tried and true method of better security.

Pairing low-tech practical solutions with high-tech systems is the best way to make a comprehensive security system. Comparing a door reinforcement kit against an alarm system is ultimately a bad move since they both independently improve your security. The best comprehensive security plan involves planning first and foremost, and a combination of high and low-tech solutions.

The best low-tech solution is a door reinforcement kit. High-security steel exterior doors start at thousands of dollars and quickly go up. Unless you have an extreme budget, your money is probably better invested in a door reinforcement kit.

Why Reinforce Your Door?

Security alarms work great. They can deter intruders, and let everyone know when somebody breaks in. But they don’t do anything to actually keep anyone from getting in.

Reinforcing a door is the tried and true method of home security.

People have been barring doors since doors were invented, and similarly, people have been breaking through doors. Unfortunately, people never stopped breaking through doors.

80% of break-ins occur through a door. Most burglaries also occur while most people are out of the house: between 10 am and 3 pm. If you don’t want someone rummaging through your stuff while you are out, you should reinforce your door. You can’t place a door bar or brace on the opposite side of the door you left through- so a door and frame that is reinforced is the best bet for security.

Break-ins occur in even more frequency when disasters and emergencies happen. Communities can band together during tough times, but the unfortunate and lesser-known truth is that opportunists show themselves as well.

Having a disaster or emergency get even worse with a home invasion is the last thing you want happening to you and your family.

The Final Word

Doors have been broken through for as long as doors have been around. If you have been a victim of a break-in you know that it is a harrowing experience. Even if you are not present at your home at the time of the break-in, the thought of someone violating your privacy and safety can be maddening.

One thought on “Best Door Reinforcement Kit for Home Security

  • The size of the optimum door reinforcement lock must be considered by each purchase. It must match the width, height, and thickness of your door. If it doesn’t, the lock will be rendered worthless and will have been a waste of money.
