SecuriGuard Magnetic Cylinder Protector

QAL school lock magnetic cylinder protector

This concealed cylinder can be used on a classroom lock and resists vandalism, bumping, and unauthorized key use. It's designed to fit over removable core or standard cylinders, and prevents blocking with superglues and other forms of vandalism to the lock cylinder.

Protect Against Picking, Prying and Vandalism

The first guardplate to completely conceal the school lock cylinder and keyhole, this cylinder protector installs over existing rim or mortise locks or exit devices, and comes with 2 keys. Its sleek profile cannot be opened by ordinary magnets and shields the cylinder from attack by vandalism or picking. It has a clear aluminum finish, and no wiring or batteries are required.

What is “Bumping”?
Burglars often take a regular key and mill it down, creating a “bump key.” The bump key is inserted into the lock and with a tap of a hammer, the lock opens. It’s so easy a child can do it! The technique has been around for over 20 years and is spreading like wildfire thanks to the internet.
