Protect your building from unwanted entry. Tested and verified by an independent testing lab, the bump-resistant cylinder is an option available with Corbin Russwin conventional and Pyramid patented security and high-security cylinders on our mortise, cylindrical and exit device hardware and more.
Bump-resistant cylinders are designed for use with all Corbin Russwin locking hardware:
- Cylindrical locks
- Mortise locks
- Exit devices
- Access control locks
- Unit locks
- Auxiliary locks
Note: Bumping is when a “bump key” is inserted into the cylinder and struck using a mallet or hammer type object. The bump key is specifically designed to transfer the energy from the force of the blow to create a separation in the cylinder’s pins which compromises the lock allowing it to open.
