These hard-working multi-purpose electromagnetic locks enhance building security and install quickly.

Several standard features make these magnets the "workhorse" of the industry. The adjustable mounting bracket has been enhanced with keyhole mounting to support the magnet's weight during initial installation, freeing the installer's hands to affix the magnet mounting screws. The removable cavity cover offers quick, easy access to wiring.
