Fail-safe electric deadbolts. Perfect for use on narrow stile doors. Complete with angle, mortise or flush mount strikes. Use with standard key or push button switch. Model 103 is a compact electric lock, simple to install on all types of doors. The door is locked or unlocked by remote switch, key switch, time programmer or other electrical contact which interrupts the power. Model 103 is our standard “fail-safe” unit which projects the bolt only while power is “on.” When the power is “off” the bolt retracts.
