Twice the Lock, Double the Safety! Secure Your Heavy Sliding Doors with Two CALDEVER Locks.

For those larger and heavier sliding doors, we advise popping on a pair of our window locks. It's the best way to ramp up your protection!

Large and heavy sliding doors demand extra safety measures due to their size and weight. Using two adhesive sliding door locks instead of one provides enhanced security for a few reasons:

  • Increased Strength: The combined strength of two locks can better withstand the force exerted by a large, heavy door, helping prevent any accidental or intentional opening.
  • Greater Load Distribution & Inertia Handling: Two locks spread the load more evenly across the door, reducing the likelihood of either lock failing due to excessive pressure. They also better handle the increased inertia from the door's movement, helping to keep the door securely positioned.

Before You Buy, Measure Your Way! Ensure CALDEVER sliding door Locks Fit the Gap Between Your Sliding Doors or Windows.

The gap between two sliding doors or windows must range from 0.28 to 1.38 inches.

  • In order for the sliding door or window to open smoothly when unlocked, please ensure that the gap between them exceeds 0.28 inches, which is the thickness of a child-proof door lock when not open.
  • Conversely, to prevent the door or window from being opened when locked, the gap between them should be kept below 1.38 inches, which is the maximum height of a sliding glass door lock when opened.

Installation steps.

  1. Ensure that the surface of the sliding glass door or window is clean and free from moisture or dust before proceeding. Please note that the sliding glass door lock is designed for use on smooth and flat surfaces only.
  2. Peel off the sticker from the adhesive and carefully apply it onto the glass. Press the base firmly with your hand to remove any air bubbles in the adhesive. It's important to align both ends of the unlocked door lock parallel to the sliding door frame.
  3. Once the sliding patio door lock is installed, allow it to remain on the glass for 48 hours. This ensures a secure and firm bond before using it.
  4. Congratulations! The installation is now complete. If you have a large and heavy sliding door, we recommend installing two door locks at different positions, one above and one below, for added security.

This product works really well and is surprising very durable. Just make sure your placement is perfect the first time because the adhesive is so strong that you can't peel and restick.

Now that he has figured out the sliding glass door lock and has the strength to open it, we were up the creek. Constantly opening the door to escape, leaving door open to let the cool air out, letting out the dog... this was exactly the thing we needed to keep the door shut. It gives a little added layer of security feeling for when we go to bed at night as it's another obstacle for a would-be intruder to overcome besides the door lock and the board we put in the door. Tried another one first, but it was too thick for the door to pass over it when it opened. This one was a hair thinner, and it fit just right. Installation very easy. Would recommend.

My 2-year-old used to run outside whenever he wanted, but this lock has been a game changer! We installed it at the top of our sliding door, and now he can’t just slip out on his own. Installation was a breeze—it took less than a minute! It’s been in place for months now and is still in perfect condition, even with kids tugging on it. The adhesive is incredibly strong, and I’m confident this will stay securely on our door for years to come. Highly recommend for any parent looking for extra peace of mind!

Really like these. I've got double sliding doors and was trying to find a way to keep kiddos from opening. I put one on each door and now even unlocked my kids can't open the door. I cleaned the glass with alcohol before applying. They seem to hold well. I've not tried crazy force on them but did what I think the kids can and no issues with breaking or falling off. I'm sure if you slammed them hard or something they may fail but you got to think about design and actual use case.Overall happy with. Company also has good customer service as I had one (out of 4 pavk) with an issue and they replaced the one without any troubles.

These sliding glass door locks were disappointing. Despite being advertised as strong, they didn’t hold securely, and the adhesive lost the grip way too easily. For a product meant to ensure child safety, it falls short on reliability. Wouldn’t recommend for serious security needs.

Works great but am a little worried when my toddler can up stuff with more strength to see if the stickers will hold. So far so good!
