The Dortronics 3300 Series Electric Strikes were tested to withstand a 1,000-pound pull test, run through 250,000 cycles and are now UL Listed Burglary Resistant Electric Strikes. On display at ASIS 2009, the popular series is compatible with most aluminum door frame cutouts and is suitable for most wood and hollow metal door frames. The 3300 Series Electric Strikes come complete with an ANSI strike plate for hollow metal door frames or with a 9-inch-tall strike plate for installation on wood door frames. Both styles can accommodate a deep door latch keeper.
