More Info

Single cylinder deadlocks provide for utmost safety and security. Their deadbolt construction will resist intruder attempts at  breaking the lock, even when using a hammer to try to smash the lock. Single cylinder locks also adhere to fire safety codes by permitting quick and easy exit in the case of a fire emergency by simply rotating a lever on  the inside, thereby retracting the latchbolt.
