Securitron's Shear Aligning Magnalock "SAM2-24" is a smaller, 24 Volt (only) version of the original "SAM" Magnalock and is intended for installations where concealed mounting in the door and frame is desired. As with the original SAM, the operating features allow self-alignment while securing the door when it closes.

The SAM2 is designed to operate with one-way swing, bidirectional swing or sliding type doors. On swing type doors the lock installs horizontally in the top or bottom of the door frame or may be installed vertically in the door frame side. For slider type door applications the lock must be installed horizontally for proper operation. These units have also been designed to unlock even if a preload is applied to the door.
