If you are thinking about weather mortice lock or cylindrical lock is appropriate for your door, you are right place to learn. When it comes to purchasing hardware for your new door, or replacing hardware in your existing door, there are several things that you need to consider.  First of all, what type of locking mechanism do I want/need?  There are two different types of locks to consider when making this choice: cylinder locks (or tubular locks) and mortise locks.  You will find that while one is more secure, it is also more expensive.  The other is less expensive and therefore more popular.  Let’s get into the differences.


Cylinder style locks are the most common type of locks that we sell.  Unlike the common latch that is a part of the knob/lever assembly, a cylinder deadbolt is not spring-loaded and is not beveled.  For the door to open and close, the deadbolt must be fully retracted.  If installed properly, the dead bolt also extends much farther into the door jamb than the regular latch.  The farther the dead bolt extends into the doorframe, the harder it will be for someone to force the door open.

Cylinder locks are easy to identify.  If you look at the short edge of your door and you see two distinct strike plates, then you already have a cylinder lock installed.  Most of these locks have standard size holes that were drilled into the door.  That makes these locks easy to replace.  Many cylinder locks have a single outside plate that covers both the deadbolt and the latch, but some locks use two separate plates in place of a single outside plate.  This type of hardware is called sectional and can be a better choice if you are replacing hardware and discover that your holes were not drilled standard.

We can send you some information on how to measure your door to see if your hardware is standard or not.


Mortise locks are one of the most secure forms of residential hardware available today.  What makes mortise locks so much more secure than their cylinder counterparts?  A pocket cut into the short edge of the door, allows a longer and thicker mortise box to slide into the door itself, providing superior protection.  You will find that these types of locks require special door preparation.  Consequently, mortise locks also tend to be more expensive than typical cylinder locks.  When you purchase your hardware from us, we will drill all of the holes necessary so that your hardware will just slide into place when it comes time to install it.

If you are wanting to replace your existing handle set, you will need to take careful measurements as not all mortise boxes have the same dimensions.  If you currently have cylinder type hardware on your door, it is possible to replace with mortise hardware, but not all mortise boxes will cover the tubular holes already drilled in your door.  Our hardware expert will be happy to talk with you and try to find something that will fit your needs.
