Review on Defender Security 4003 Sliding Spacing by James Cruz

This good value patio lock is perfect for my patio door. I'm looking at a whole range of other patio door locks that are expensive but don't fit my door and even buy a Deerfield sliding glass door lock (aluminum frame - white) which I find unreliable and can rattle and wobble. door and it gets weaker. I thought someone had hacked my high security front door locks, but it looks like they hacked the Deerfield patio lock instead. This lock is cheap and works like a charm. I could get this at my local hardware store but not in black. It seems that the black color is not in demand for this lock, so it would have to be made to special order. I chose to order it through Revain for 2 day delivery rather than ordering it specifically from my local hardware store and waiting 1-2 weeks. I am very happy with this lock and would highly recommend it to anyone with a sliding patio door. If you want to see what the installation looks like, watch the youtube video below Extra security. The installation is the same as in the video link above. And the functionality will be the same, except for the ability to block keys.
