BEST DEADBOLT LOCK T SERIES

Premium materials, security, and performance.

Built with identical tubular assemblies, the 7T and the 8T both fit standard door preps. The 7T can be found in low-security areas, such as bathrooms or storage rooms. The 8T is often paired with a cylindrical lock in commercial office spaces, residential applications and other spaces where there is a greater need for security and, more specifically, a deadbolt that is more resistant to brute force attack. The BEST 8T Deadbolt is also available with lead line options, making it a good solution for radioactive doors (MRI, x-ray, etc.) in healthcare facilities.

Often paired with a cylindrical lock in commercial office spaces, residential applications and other spaces where there is a greater need for security.

For low-security areas, such as bathrooms or storage rooms.Incorporating top quality design, engineering, and materials, BEST’s T Series tubular deadbolts are easy to install, integrate, and rely on for durable security. Our T Series deadbolts provide for simple installation, without compromising security and performance.
