Door Hardware Help
Single cylinder deadbolts feature a keyed lock on the exterior of a door and a thumb turn on the interior. Typically, they're used in residential applications and exist as the most commonly used deadbolt.
These deadbolts are akin to single cylinder but have a keyed lock on the interior of the door instead of a thumb turn. So, double cylinder means two keyed locks. These are often found in commercial applications, as they are considered hazardous in residential use in the event of emergencies. They are more difficult for intruders to break into, as keys are needed for each side of the door.
A single-sided deadbolt has a thumb turn on the interior of the door and nothing on the outside.
Yes! Because they use a 1" throw bolt that extends into the jamb, they're a much more secure option as opposed to a standalone keyed knob or lever. When installed correctly, deadbolts have two 3" screws that attach to the strike plate. This makes it quite difficult to kick in the door.
Deadbolt locks can be picked like keyed knobs and levers, but with a solid jamb around it, they aren't easily kicked in. It would take great force to break in a door with deadbolt, in which case the jamb would fail before the deadbolt.
Single cylinder deadbolts are found in most homes, as double cylinder deadbolts can be dangerous in situations where quick exits are necessary (like fires). However, they can be picked just as a traditional keyed knob or lever. The important thing to ensure during installation is that your door jamb is solid, as that will make an impact during a potential break-in. An intruder will not be able to easily kick the door in if the jamb is in excellent condition.
It's also important to note that with the thumb turn mechanism, single cylinder deadbolts are easy for small children to open. Ensure these areas are kept off limits to children.
When choosing a single cylinder deadbolt, the quality and appearance of it matters. You want it to match your door, so it enhances the curb appeal instead of detracting from it. They're often offered by a variety of stylish finishes. Most importantly, you should only purchase deadbolts from trustworthy brands like those we carry here at Direct Door Hardware. If you can, choose an ANSI Grade 1 deadbolt, as these offer the most protection. If you aren't sure which deadbolt your home needs, we would be more than happy to help you find an excellent one!
There are many different types of deadbolts on the market today, from top brands like Schlage, Sure-Loc, Baldwin, Weslock, and so many more. These come in an array of finishes, which is important if you're looking for hardware to match your door. However, the best deadbolts are those with ANSI grades. Grade I deadbolts offer the most security, whereas Grade II offer slightly less. Look for these grades when choosing a new deadbolt for your home, business, or other location. Higher quality deadbolts often come at a higher price. Security is not an area to penny pinch, as you need the best protection you can afford to keep your family, employees, and/or business secure.
