Deadbolts are one of the most popular lock types in the market today and are commonly found on both residential and commercial properties. While most people assume a deadbolt lock automatically offers a higher level of security opposed to a regular spring bolt lock, there are various types of deadbolt locks, each with it’s own set of attributes to consider.
A deadbolt lock consists of a locking mechanism that can be opened by rotating the cylinder of the lock via a handle that is attached to it on either one side or both sides of a door, essentially making the door more secured. it is very commonly used as an additional lock on a door which already has a spring bolt lock installed on it.
There are two main deadbolt designs available on the market today – a single cylinder or double cylinder lock. While the single cylinder lock usually uses a keyed entry outside (allowing only someone who has the key to bypass it from the outside and gain entry) the double cylinder deadbolt requires a key to bypass it from either sides of the door, thus making it a more secured option.
Panic bars typically use a “rim” mechanism bolt or latch. It does not function like a deadbolt. A rim mechanism is designed to have a heavy duty bolt extend outward (vertically or horizontally) from the lock itself. With enough force these locks can be opened, but proper installation prevents the lock from being reached from the outside of the door.
The “classroom style” is a knob or lever entry handle with a mortise lock mechanism, with the ability to be opened from the inside regardless of whether the mechanism is in the locked or unlocked position from the outside. This is for safety reasons in a classroom, and just the feature of a classroom style mechanism. Other types of mortise mechanisms – passageway, entrance lock, classroom lock, storeroom lock, dormitory/exit lock (typical on apartment doors), privacy lock
Another available option is the vertical deadbolt which is essentially jimmy proof and was invented by Samuel Segal, an NYPD Officer who wanted to further protect New York residents from intruders “jimmying” or expanding the door frame to gain entry to a room or building.
Locks in public facilities meant for private or limited usage may be any style, but legally still required to have a thumb turn mechanism or knob available to unlock from the inside of the room.
Another popular option is the push-button deadbolt mechanism which can be mechanical or electrical, depending on your specific need and budget.
Whichever deadbolt you decide on using it is important to have it installed by an experienced and licensed Locksmith. Also make sure that your deadbolt is clearly labeled as a grade 1 or grade 2. Avoid using hardware that is marked as “grade 3” or the generic term “professional grade”. We also recommend you ensure that it extends at least 1 inch into the door jam so that the door is less susceptible to be kicked in, in case of a break in attempt. Last but not least it is highly recommended that the strike plate which attaches to the actual door frame is reinforced and is at least 4-6 inches long with screws that are at a minimum 3 inches long.
