HauSun Patio Sliding Door Security Foot Lock Kick Lock, Fits on Top Rail-Childproof patio Door guardian-or Bottom Rail-Foot Operated-Keep Your Family Safe and Secure(1 Pack,White)

Installation was relatively simple. I used a 5/64 drill bit for starter holes and then a Phillips screwdriver with the screws provided in the kit.It is a great relief that my toddlers can no longer fling the door to the patio open at will. Sometimes their tiny faces will peep through the gap provided by the second slot and I chuckle as I slide a popsicle through while dad watches them on the patio.It’s great! Bought a second one.

This lock is amazing.used to use the bar that you put on sliding glass doors, but they are a pain in the butt. This installs quickly and you can lock and unlock it at the press of a button.it is so much more convenient.

Saw this at an air B n B I stayed at to lock patio door. Worked so good I bought 2 for my house, took the broomstick out of the track. Worth the $$

Nice quality and great price.

So after reading the reviews of other people shattering their sliding glass doors while installing this lock, my husband and I took to referring to it as the "scary lock." Phrases such as "did you order the scary lock?" and "when is the scary lock arriving?" were pretty common in our household.Anyways... I watched a ton of installation videos on youtube before trying ours and here's my list of tips.1. When you attach the lock to the actual door, make sure you put the lock as close to the non-glasss edge of the door as possible to ensure the screws don't go through and hit your glass. Look at your door from all angles and if you have even a suspicion that you're going to hit the glass, DONT DO IT. Pick a different lock.2. When attaching the lock receiver to the doorframe, keep in mind that the screws provided are pretty long and may screw your door shut if you're not careful. This leaves you with a few options. First, if you are installing at the lock/receiver to the top of the door, you may be able to put the screws in the clearance space that the installers used to get the door into the track. This has two benefits, not only will it allow the door to slide without hitting the screws but it will make it close to impossible to lift the door out of the track, thus increasing security. Second, if you're installing the lock/receiver at the bottom of the door and the screws are too long to avoid screwing your door shut, they can easily be replaced for less than 50 cents with shorter screws.3. Before you begin drilling any holes, mark where you need to drill with a pen and once again make sure you're not going to hit glass.4. Before you put the screws in, use a drill bit to create a small guidance hole. This will not only make the screw installation easier but will also allow you to go incredibly slowly and make sure, once again, that you're not going to hit the glass.We did all of the above and the installation still only took about 10 minutes. We're definitely going to be getting some similar locks for our downstairs windows too.

Quality and functionality are fine. However, on your typical sliding door there aren't many good places to mount it and the parts themselves are bulky and can interfere with closing and opening blinds etc.

Great product

When I purchased this I apparently only saw Amazons defaulted “highest reviews” so I thought this would be a great purchase as my toddler knows how to open the back door now. While installing, and doing as the instructions state, we shattered our glass door. I then started digging at other reviews and there are sooooo many people who have done the same. It’s not operator error, it’s an issue with this item. There’s no information about compatibility or warning.Save yourself a $1200 glass replacement!
