ScrewTight security door chain installed on a door that allows it to be partially opened while still providing some level of security. It consists of a chain attached to the door frame and a sliding bar or plate attached to the door itself. When engaged, the chain restricts how far the door can be opened, allowing for safe interaction with visitors without fully opening the door. This provides an additional layer of security by preventing unauthorized entry while allowing communication and limited access. High-quality security door chains are designed to be sturdy and reliable, ensuring long-lasting security for your door. Compared to more complex security systems, ScrewTight security door chains are a cost-effective option for improving door security.
