Questions & Answers
What is a deadbolt?
A deadbolt is a locking mechanism distinct from a spring bolt lock because it can only be moved to the open position by rotating the lock cylinder with a key. Unlike traditional locks, deadbolts do not have a spring-loaded mechanism, making them more resistant to forced entry. They are often used in conjunction with a regular keyed lock to enhance security for residential and commercial properties. Deadbolts come in various types, such as single-cylinder and double-cylinder, each catering to different security needs and installation preferences. When choosing a deadbolt, it's crucial to consider its ANSI grade rating, which indicates its durability and strength against tampering or picking.
How does a deadbolt earn an ANSI Grade 1?
A deadbolt rated as Grade 1 must withstand 250-thousand cycles and 10 door strikes with a hammer.
What is a double cylinder deadbolt?
Double cylinder deadbolts have a key cylinder on both sides of the door. A double cylinder deadbolt requires a key to unlock on both sides of the door. In the event a burglar broke the glass in your door, they would still need a key to unlock the door.
