Not knowing who’s knocking on the door when one isn’t expecting any visitors can leave a person hesitant to answer. And if no intercom system is available, trying to hear what the person on the other side is saying is often a challenge.
The Right Lock allows the user to open the door about two inches or so, and the solid metal-looking design is touted as preventing an easy forced entry. It appears that installation is fairly easy with a drill and screwdriver bit.
The idea seems to have some good potential, but it’s doubtful that this item alone would really prevent a forced entry if an intruder where determined to gain entry. In addition, many have chain locks which really serve the same purpose. Interested backers might also like to check out McChi lock and Burglar Blocker. This campaign seeks to raise $15,000 on Kickstarter. Backers get one lock for $30 with an expected delivery of May 2015.
