Liver savers!
These have been a life saver to our front and back doors now that our 4 year olds have established how to open our arms reach safety locks and can unlock those. These are super sturdy, fairly heavy, easy to install and maneuver. We purchased the black ones to go with the rest of our hardware. They can fit/ adjust to any door frame.

Added level of safety for Peace of Mind!
Added level of safety for Peace of Mind ! I have patio doors leading to the backyard and pool and have grandkids around a lot . We have lever type door handles with regular locks and even alarm sensors on those doors but these locks provide another level of safety and peace of mind. We installed at the top of the door so no chance little ones can get to it and figure out how to unlock. Easy to install, functional and are not an eye sore at all. Great product!!

Highly secure and easy to install
I recently purchased the Steinwhale 4Pack Home Security Door Latches, and I am thoroughly impressed. These latches offer a solid sense of security for my home, with a heavy-duty design that feels incredibly sturdy. The build quality is excellent, made from durable materials that give me confidence in their longevity. Installation was a breeze. Each latch came with all the necessary hardware, and the instructions were straightforward. I had all four latches installed in less than 30 minutes with just a few basic tools. The sleek and low-profile design is perfect—it blends seamlessly with my doors without being an eyesore. One of the standout features is how effective they are in preventing forced entry. Once engaged, the latch keeps the door firmly secured, providing an additional layer of security beyond a standard lock or deadbolt. It’s great peace of mind, especially for anyone who wants extra security for their home or apartment. Overall, the Steinwhale latches are an excellent investment. The value you get with the 4-pack is unbeatable, and I would highly recommend these to anyone looking for easy-to-install, high-quality home

Excellent door locks.
These are my favorite locks to child proof my doors. They can be installed high and they are extremely strong. I used much longer screws than came with the package for added security. No one is pushing passed these to force entry. They are extremely easy to install and use. They have held their color and haven’t worn out in the few years I’ve been using them. Would recommend, great value for money.

Great to keep our kids out of stuff and upgraded security
We had a problem with our kids unlocking the normal locks in the house and walking out the front door, pantry, and basement. This three pack covered all areas we needed. We placed them at a height that they couldn’t reach. The lock is easy to open and close and does a good job quickly locking closed what you need closed. It was easy to install and we needed up not using the screws it came with. For more security I highly recommend using 3in deck screws. If there were to be an attempted break in the force of the kicks will spread out across the wall rather than at the door. The longer screws I used will definitely help to keep unwanted out. They aesthetically look very pleasing to the eye as well. I would highly recommend this product to others.
