Prime-Line U 9842 Clear Lucite, Glass Surface Patio Door Lock, Self Adhesive (2 Pack)

I've been trying for months to fix the latch to our slide out. The mirrored sliding doors kept sliding every time it the RV was in motion. I ordered 3 different items and returned them. Then I saw this for $3+, so simple a product, so easy to attach and it works. It keeps the sliding mirrored doors from sliding while our RV is in motion. A bonus, 2 in a pack.

Bought this for mirror closet door stop in our filth wheel, I had three sets of the factory ones break so I got these and so far they work great.

I love this! I'm going through construction on my house and its older so the sliding glass door latches and locks don't work. So essentially literally anyone could just slide the door open. I bought this to at least act as a buffer until the construction is over and its perfect! I have it so the door cant open more than an inch when its in use and it is super stuck to the door. I have even forgotten it was there and accidentally went to slide the door open with some force and it stopped the door right in its tracks and didn't budge or break. Very durable and very easy to use. Perfect for keeping people out or keeping little ones in.

The spring loaded mechanism broke within the first five uses. The tiny spring loaded peg is made out of an very thin plastic (smaller than the size of a needle). It should have been made out of some sort of metal. The adhesive strip did not stick very well. The directions say that the adhesive will reach its 90% bond in 72 hours... I hope so because so far it is a piece of garbage. As the title reads, it is a good idea but cheaply made.UPDATE: I installed the second lock at my parents house. The tiny spring loaded peg broker again. Also, the adhesive strip did not work as well either. It has stayed on the sliding door at my home now that it has been over 72 hours, but I did not test it by opening the door and hitting the lock. I think it might hold to my toddler's strength, but I wouldn't use it as a anti theft mechanism. Also, something to keep in mind, this time, when the door slid open, it would hit the lock which made it 100% useless on this door. So know that if the gap between the sliding door and the fixed door is very small it will not work for you.I hate to give bad reviews, but unfortunately this product deserves it.UPDATE#2: After having the only one of two locks for a very short time (no more than a month), it has come off when my wife tried to open the door and accidentally left it locked. She didn't use much force and it didn't hold, so I can say that this product is a complete failure.

We purchased a used travel trailer with sliding mirrored closet doors. One of the door latches was broken, allowing the door to slide back and forth during travel time. I found recommendations on-line to try this product. It is almost unnoticeable placed at the bottom of the door and works great. Very easy to apply and allows the doors to slide freely when unlocked. Plus, there is are two in a pack for those that want to apply two for extra security.The price from this seller was great, qualified for free shipping and arrived quickly.The only thing I would change about the lock is the little black plastic lock release, I wish it was metal, I think it would be more durable, but I haven't heard that it is a problem for anyone in my research.I would definitely buy this product and from this seller!!

I bought this to protect my three grandsons, ages 5yrs, 3 yrs, and 18mo. They just moved into a third floor apartment with a sliding glass door to a balcony. And, of course, they always wanted to go outside and play on the balcony. This little gadget was the perfect solution to keeping them from opening the door and heading outside without supervision. It took seconds to install, no tools required. Initially, I was concerned that the adhesive might not hold in the Arizona summer heat. But it has been over a month since I installed it, every day in the triple digits, and it is holding tight. The kids can't reach it, and it is easy for the adults to install and use. Great product!

Since I keep forgetting that the lock is...well...locked, I keep bashing our sliding glass door into it. It hasn't fallen off or broken, so it gets high marks from me. We've also installed them on sliding windows to keep our kids inside and have had no issues.Installation was simple...follow the instructions to the letter and I think you'll be happy.One of the locks we received was damaged. I contacted the seller and received a new package of 2 locks within days. If I had more doors and windows, I'd absolutely buy more. Please note: these locks aren't a replacement for window bars...they suffice for us but might not be what you need for security/peace of mind, especially for higher floors.UPDATE: The black pin that locks the swivel open broke after a few months. The pin needs to be much stronger. Be sure to mount the lock with the hinge at a 90 degree angle to the door/window opening...hitting the side rather than along the hinge might give greater longevity. Wish I'd realized that before installing them.

The media could not be loaded. Not a whole lot to say about this besides, I’ve been using it for years it’s never failed me. It’s super strong. Definitely a recommendation if you have small kids or you have a door lock that’s broken and you don’t want to use a broom. Easy simple use
