I have been searching high and low for a product to keep my toddler safe who is into everything and has zero fear. I research the heck out of everything before deciding to purchase something, so I'm hoping to pass along my wisdom / results / insight and save you some time.
The GlideLok was easy to install. I did it myself with my drill and drill bit. The instructions tell you what size to use. This thing is heavy duty and I LOVE that it has the option to fit my door to the garage so hubby can let himself in from outside the door by sliding it one way to unlock or the other way to lock.
I have an incredibly strong toddler who doesn't give up easily. This keeps him safe!
