I bought two different types and these are better and a few dollars more. I like the crank to open them, they are attached and easy to use. Second, locks that you can use to lock it. Not complete proof, but a little more certainty never hurts.
Pros
FUNCTIONAL FOR BUILT-IN BUTTON DESIGN – Easy to use without additional tools. Central axis design that opens and closes both sides at the same time, which makes the setup 10 times faster than others.
