Security: Electric Strikes

The HES 5900 series offers unmatched performance and reliability. This secure unit requires no cutout on the frame for fast, easy installation. It accommodates 1/2-5/8" latchbolts (with 1/8" door gap). With patented vertical adjustability to accommodate door sag or misalignment, the 5900 sets the standard for concealed electric strikes.


A standard electric strike requires a cutout on the side of the door frame to allow the extended latchbolt to exit the frame. In contrast, the 5900 is designed to utilize special internal ramps to eject the latchbolt from a unmodified frame.
