Question: 1 / 400

When installing a mortise cylinder, in what direction should the keyway be oriented?

3 o'clock

12 o'clock

The keyway of a mortise cylinder should be oriented at 12 o'clock to ensure proper alignment and functionality. This vertical orientation facilitates easy access when inserting and removing the key, allowing for smooth operation of the locking mechanism. It also ensures that the keyway is positioned correctly for use in most standard hardware applications, which is critical for consistent performance.

Choosing this orientation minimizes the risk of the key binding or not engaging properly inside the cylinder, which can occur if the keyway is positioned incorrectly. The 12 o'clock position is the industry standard and promotes better ergonomic handling for users accessing the lock system.
