The HES 8000 series is a compact, high-performance electric strike featuring a unique concealed design for use with cylindrical locksets. No cutting on the frame is required. Simply remove the existing strike plate, adjust the vertical alignment feature to the latchbolt centerline, and install. Its strength is derived from a unique keeper pin locking design, enabling the 8000 to exceed the ratings of the frame, door and locking hardware. This field selectable fail secure/fail safe unit is easy to install and accommodates latchbolts up to 5/8" throw. Each Complete Pac conveniently pairs the reliability of HES electric strike with the flexibility of multiple faceplates in a single simple package. The 8000C includes an 8000 strike body, the 801 faceplate for cylindrical locksets in ANSI metal jambs and the 801A faceplate for cylindrical locksets or spring latches in aluminum frames.
