Does Tri-Bolt Really Work?
The Tri-Bolt is a patented one-sided security lock that is designed to handle common issues with deadbolts. Placed at the top of a closed door, it prevents the door from being opened even if the deadbolt is reachable by children or unlocked from the outside by an intruder through the use of a pin. Since the device is not seen from the outside, intruders will not know what it is that’s preventing them from unlocking the door, thereby making locks foolproof. Additionally, the Tri-Bolt offers other purpose. It functions to fill gaps in the door’s edges, preventing weather stripping and keeping heat and cold from escaping. The product also claims to be designed safe from accidental incidents of being locked in.
