Factors to Consider When Securing Your Doors

  • Door dimensions

    The standard front door is between 30 to 36-inches wide and up to 80-inches tall. However, remember each door is different. Before buying door security equipment, start by measuring your door’s thickness, height and width to pick the right option for your home. It’s best to look for a door security bar or jammer that adjusts to make sure it fits your door and other doors around your home.

  • Placement

    Think about where you’ll place your door security bar or door lock. Some door security equipment only works on hinged doors while others help protect both patio sliding doors and hinged doors. Before buying a door security bar, double check where it should be placed. Also, keep your home’s floors in mind because while many door security bars and jammers work on wood or tile floors, others may not work on floor types such as carpet or linoleum.

  • Door design

    Look for durable door security equipment made to withstand force about 350 pounds – the weight of a tiger. Most popular door security bars are made with sturdy steel and metal which is stronger than plastic door security options. You’ll also want to make sure the door lock or jammer doesn’t damage your floors. Look for door security equipment with rubber feet to avoid scratching your floors while withstanding pressure.

  • Installation

    Some door security bars can be pressure-mounted by simply angling the bar less than an inch from the door and connecting it to the doorknob. Pressure-mounted door security equipment is perfect for traveling or rental properties because they require little to no installation. On the other hand, hardware-mounted door security options are known to be more sturdy but may require professional installation or drilling to keep the jammer or lock in place.

Understanding Door Security Options Before Buying

  • Door Lock Reinforcer

    Door lock reinforcers are positioned around your door’s existing lock for added security against picking or breaking the lock to force entry. They’re often portable and easy to install by simply snapping into place around the lock. Before buying a door lock reinforcer, double check if the reinforcer works for your lock because some may not work for smart locks or horizontal locks.

  • Door Jammers

    Door jammers are the most common front door security measure. They’re made of plastic or steel and placed on the floor less than an inch from the door at an angle that latches to the doorknob to stay in place. Door jammers are often pressure-mounted to be portable and easy to remove in the event of an emergency.

  • Door Security Bars

    A door security bar is often placed across the middle of the door to prevent burglars from pushing the door. Some are hardware-mounted, while others are easy to install with pressure-mounting for sliding doors, traveling and apartments. Door security bars are often adjustable to fit the door’s width perfectly.

Door Security Tips

  • Lock your door. Even if you’re using added door security, the first protective measure is to keep your home’s doors locked at all times to prevent lurkers from easily entering your home. If your lock isn’t sturdy enough, consider a smart lock to pair with a monitored security system for extra home security.
  • Go windowless. Door windows allow light to filter into your home and pose a home security risk. If the window is located within arm’s reach of your lock, it may be easier to break in. If you have a door with a window, consider adding a glass break sensor to instantly be alerted if your door’s glass is broken.
  • Protect your sliding doors. Make sure your sliding doors are made from reinforced glass or plastic (like polycarbonate), and not thin, easy-to-break glass. Place a wooden or metal dowel in the track – no more than 1/4″ less than the track length – to prevent forced entry. And consider installing curtains so lurkers cannot see inside easily.
  • Install a deadbolt. Doors are only as strong as their lock. Deadbolt locks add additional security by only opening with a rotating key without the spring most standard locks have. They’re known to resist force better than most, and can often only be opened from inside if you don’t have the key.
