3 best double cylinders
Double cylinders are a type of deadbolt lock commonly used in residential and commercial settings as part of door hardware. These locks provide an additional layer of security compared to single-cylinder deadbolts. The key distinction lies in the way they operate.
Unlike single-cylinder deadbolts, which have a key cylinder on one side and a thumb turn on the other, double-cylinder deadbolts have key cylinders on both sides. This means that to unlock or lock the door, a key is required from either side. The presence of key access on both sides enhances security by preventing certain methods of unauthorized entry, such as reaching through a broken window to unlock the door.
While double-cylinder deadbolts offer heightened security, they also come with some considerations. In the event of an emergency, such as a fire, occupants may face challenges exiting quickly because a key is needed to unlock the door from the inside. Building codes and regulations often dictate where and how double-cylinder deadbolts can be used to ensure safety.
When installing or choosing a double-cylinder deadbolt, it's crucial to follow local building codes and consider factors like accessibility and emergency egress requirements.Additionally, users should keep keys readily accessible but out of reach of potential intruders.
In summary, double-cylinder deadbolts are a type of door hardware lock that requires a key for both sides of the door, providing an extra layer of security but requiring careful consideration of safety measures.
