The 7000 Series Electric Strikes have a modular design which enables the user to determine the function, either fail secure or fail safe, at the time of installation by the positioning of the solenoid within the unit. There are five different option kits; the 701 ANSI 4-7/8" option and the 702 7-15/16" option, both of which accommodate cylindrical latchbolts up to 5/8" throw. The 783, 786 and 789 options accommodate rim mounted panic exit devices with up to 3/4" throw latchbolts. The unique design of the keeper module enables the unit to operate under 30 lbs. of door loading (fail secure only). The 7000 series have an internally mounted solenoid for compactness and ease of installation in hollow metal, concrete filled metal, aluminum and wood jambs. The heavy duty construction of the 7000 series electric strikes makes them ideal for high usage.
