The Bumpstop lock employs an innovative design that utilizes a unique reverse rake tapered driver pin, high performance springs and tightly machined cylinder chambers. The lock is designed to resist “lock bumping,” a method of manipulating an in-line pin tumbler cylinder to open that is being used increasingly, according to the supplier. During a bump attempt, this solution prevents the transfer of force from the bump key to the pins and blocks rotation of the cylinder.
