Description
HES 8500-12/24D-630 Overview
The HES 8500-12/24D-630 is a compact, concealed electric strike designed specifically for mortise locksets without deadbolts. Featuring a durable satin stainless steel finish, dual-voltage 12/24 VDC operation, and a fire-rated design, the 8500 Series is commonly selected for commercial openings where installers want a clean architectural appearance while minimizing visible frame modifications.
Unlike larger surface-mounted electric strikes, the HES 8500 installs within the frame and accommodates a 3/4 inch mortise latchbolt without requiring cutting to the face of the frame. This concealed installation helps preserve the appearance of finished aluminum, hollow metal, and steel frames while providing dependable access control performance.
