Overview
The Folger Adam 310-2 electric strike is a 3-hour fire-rated, industrial-grade electromechanical door keeper engineered for extreme heavy-duty applications in commercial buildings, hospitals, correctional facilities, and institutional access control systems. The 310 Series is a 3 hour fire-rated, industrial grade electric strike designed for extreme heavy duty applications. This industrial grade electric strike is used with cylindrical locks, mortise locks and mortise exit devices with a 1/2″ or 5/8″ throw latchbolt (without deadbolt) on single and pairs of doors.
Key Features
