Here’s a fantastic video from Lee Harvey of Door Hardware Simplified explaining the differences between Cylindrical Locks and Tubular Locks. Below the video we have include an audio transcript of the video:

Cylindrical LockI’m going to talk about cylindrical locks, and the differences between the types of cylindrical locks in the marketplace.

Primarily, you have two basic types, a tubular type of cylindrical lock, and a extra heavy duty cylindrical lock. The tubular lock, and cylindrical lock will both serve the same purpose, but one is considered more light duty than the other.

If you’ll notice, with a tubular lock you have two different pieces. You have the outside, and the inside trim. The latch bolt, if you’ll notice, has a continuous latch bolt that goes all the way through the mounting hole, the bored hole through the door.

If you notice, the hub is in the middle of that door. That’s important, because when this latch bolt engages into the trim of the outer and the inner trim mechanism, it will operate the latch bolt successfully.
There’s other advantageous of a tubular lock set but probably the more heavy duty lock set cylindrical lock on the market is this type of a heavy duty cylindrical lock.

If you’ll notice, the latch bolt is different. It doesn’t engage into the main trim like the tubular lock. This latch bolt has to engage into the retractors on the chassis itself and interlock with the retractor to allow that latch bolt to fully retract when the lever is moved. Simply installing the latch bolt is inserting the latch bolt in this already predrilled door mount.

Depending on the hand, the flushness of this latch bolt face against the edge of the door, that centers these tabs in the cylindrical lock to allow the cylindrical lock to be installed and engaged with that latch bolt, ensuring proper connection. The most important factor to remember here is the engagement of the latch bolt into the chassis.

Also included in this is the inside trim that simply goes on the inside of the door and then, of course, the other lever. The other level is not attached as it was with the tubular lock. Also what comes with these lock sets are the various types of strikes that goes with the jamb. Depending on if it’s a wood jamb, you might want to use the smaller strike. If it’s a hollow metal jamb, or a metal jam the larger strike is designed for that.
