Question: I don't understand this from the photo.  Is it a lock that's higher on the sliding door so you have to unlatch it with the door lock also?
Document: Strong adhesive makes a great bond to glass door. Put up high it keeps my toddler from getting out, also extra security as door also can not be opened from outside when lock is on. Amazing how strong a little piece of plastic can be. If you have a sliding glass door this is your best extra lock. Two come in pack.
This product is a must even if your child doesn't open the door. It is put on in seconds, not to noticeable, and gives me the piece of mind every parent needs. It is also a second form of security at night besides just the lock on the door. There is one thing no parent wants and that is for their child to get outside when they are not around, and you just never no, so please pay the few dollars and prevent anything from happening.
Sliding doors have flimsy locks anyway .. so we needed a second locking device for greater security ....  this one is inexpensive, easy to install and keeps the door from being opened .. it keeps little ones in and should frustrate an intruder enough to keep out. We also have a &#34;broom handle&#34; in the track that lets the door stay open a crack for the cat when needed.
We bought this so that our 2 year old could not open the sliding door to go outside. He can flip the traditional locks and open the doors with no problems. This plastic barrier looked and felt kind of cheap but it does the job! Our son tried to open the door several times to no avail. We also like the fact that it's clear and not too bulky. This does the job in keeping him from going outside by himself!
LOVE this product! I have a toddler who loves to play in closets & make huge messes. Most locks for sliders attach at the top of the track. I also saw the idea of using heavy duty clamps at the top. None of these solutions worked for us, because all of our closets and sliding glass doors are extra tall and I can't reach the top. This product works great for us! Easy to apply and use. You can hang at any height that works for you.
My toddler can not open the sliding glass door when this is in the lock position. Easy to install - adhesive working great two months later. I am back to buy another set as he now can climb out of his crib and my guess is that the window is next!
I can tell you that my slider has very little space between the fixed door and sliding door...Another observation that I noticed while I was attempting to make it work - the adhesive didn't seem strong enough to hold it in place. During testing, the moving glass door easily knocked the plastic lock off the glass.
My husband and I bought the flip lock for our sliding glass doors because we have a pool and a toddler at home. He started to get curious about doors and locks so we needed extra protection. Sometimes after we unlock the doors and pull as hard as we can the door will not open and we forget the flip lock is in place and that lets us know it's really working and my son won't be able to open the door.
I bought this to keep my 2-year old out of his closet. He has mirrored sliding doors and there isn't ANYTHING out there to lock this type of closet. I read another review that said they purchased this product for the same purpose so thought we'd give it a try. It works!! It is so easy too! Peel off the sticker, put it on the door just as it's shown in the picture. I no longer have a toddler pulling all his clothes off the hangers instead of napping.
I have 4 children - 2 are toddlers plus I run a home daycare. A lock on a slider is a must. I was concerned if it would hold up being plastic; but it has done great so far. the adhesive is incredible and has lasted through rain, cold ad snow and even with  kids sliding the door it hasn't broken. They can just about fit their little arm out the door but nothing more than that. I highly recommend this sliding door lock!
