Review on Secure Your Home with the U S Patrol Sliding Door Lock: A Must-Have for Enhanced Safety by Charlie Dillon

Significantly less durable than described and shown as "iron"! Not as thick and heavy as the description might suggest. Made in China, so that should do it. This is enough to stop the door, but also a 1 inch square piece of wood cut to length. Paint it white if aesthetics are important to you. That's the problem, although at least one star minus. The thumbscrew that aligns with the holes on the slider is about an inch apart. In my door, this is the worst case scenario. The shorter length leaves a gap of about 1 inch. The door can be broken open easily. A screw hole is over and too big to fit the rail. So your door track needs to be the perfect length or it's useless. I was able to hack it by placing a socket adapter as a bumper at the end of the walkway at home, which luckily gives me a near perfect fit, otherwise it's back in the box and returned. Avoid the hassle of returns, but adjustable is a very vague term in the description.
