The BEST 8T Grade 1 Series Deadbolt is one of the most secure I/C Core accepting deadbolts on the market. Used either as a standalone or in conjunction with cylindrical locks for extra security.

Built with a tubular assembly, the 8T fits a standard door preps. 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 8T is also available with lead line options, making it a good solution for radioactive doors (MRI, x-ray, etc.) in healthcare facilities.
