More Info

Double cylinder deadbolts are designed for use on doors that have a small, breakable glass part that will allow a  burglar to stick in his hand and unlock the door from the inside. However, fire safety must be taken into consideration before installing a double cylinder lock. During a panic situation, we don’t want your lock keeping you captive. Therefore, before installing a double cylinder deadbolt, make sure it will be safe not only for your possessions, but for your life as well.
