How to Use (Step by Step)

  1. Attach to ac

    In order to install this security lock, you'll need to attach it to the rail found on the top of most air conditioning units that are meant to sit in a window. It's best to do this from indoors, even if your air conditioner is resting in a ground-floor window. Be sure that the little black screw is facing you and that the white piece furthest from you is pointing upward.

  2. Close Window

    Next, simply close your window as much as you can with the air conditioning unit there.

  3. Tighten Screw

    Once your window is closed, turn the little black screw on your security device in order to tighten it and thereby lock the AC unit into place. After you've done this, you can go about your daily business inside or outside the house without worrying that the unit will fall or be stolen.


  • White

    Each of these security locks is white. Since most air conditioning units for the window are either white or gray, your lock will be inconspicuous and it's unlikely that anyone will notice it's there. That means if there ever is a potential thief in your house who returns to steal later, they won't quickly understand why your unit is so immovable.

  • Compact

    The AC Security Lock is compact—not much bigger than a bar of soap. If you need to store one while your air conditioning unit isn't in your window, it won't take up much space in a drawer or cabinet. Even if you've chosen to get multiple locks for multiple AC units, these will be unlikely to crowd up your storage areas.

  • Works on Variety of Windows

    This security lock will work effectively on almost all window frames, as long as they're made from wood, aluminum, or vinyl.

Positive Points

  • Makes Home Safer

    Just like a lock on a door or window, the AC Security Lock will enhance the safety level of your home. While you're at work, sleeping in bed, or running errands, you won't need to worry that thieves are removing your AC unit and crawling through your window into your kitchen. You also won't need to be concerned that you'll arrive home from somewhere and find your upper-floor unit smashed to smithereens on the street.

  • Can be a Good Gift

    If any family member or friend of yours has their own portable air conditioning unit, this security lock may make a great gift for them on any occasion. Showing them how to use it won't take long, since some people are able to install the device in less than a minute.

Negative Points

  • May Not Attach to All Acs

    To attach this device to your air conditioning unit, that unit must have a rail on top. While most do, the occasional one may not. If yours doesn't have this design feature, this lock might not work properly for you.

Critical Advice

Make sure that you're gentle and careful when you're attaching your security lock to your air conditioning unit. If not, you may end up pushing the unit out the window yourself while doing so, defeating the whole purpose of the exercise.

Save Money

Using this security lock will reduce the chances that your air conditioning unit will fall out ( or be taken out of ) your window. That, in turn, will reduce the chance that you'll need to invest in a replacement unit.
