The HES 9400 series is a slim-line, outdoor-rated surface-mounted electric strike designed to accommodate rim exit devices with a 1/2" Pullman latch. All components are completely encased within its 5/8" thick stainless steel housing. No cutting on the frame is required for installation. Simply place the electric strike on the surface of the frame, align it with the exit latchbolt, and install. The HES 9400 ships with a 1/8" spacer plate to accommodate varying door gaps. The HES 9400 exceeds Grade 1 standards for strength and performance. It is field selectable for fail secure/fail safe operation, and for 12 or 24VDC. The HES 9400 features a smooth cover to conceal the mounting screws and provide a sleek surface for superior looks.
