    A Game Changer for Home Security

    Posted by Stephen on Aug 16th 2023

    I just snagged the Falcon D251 Double Thumbturn Deadbolt from zensupply.com and I'm feeling pretty good about it. The double thumbturn feature is a nifty addition – super easy to lock and unlock, especially when my hands are full. On the flip side, the installation instructions left me scratching my head a bit, and it took more time than expected to get it set up. Once it's up and running though, it's been a solid upgrade for my home security.
