Primus Lockout Cylinder

When you want to periodically disable and block access to a certain room in a building or an entrance door, that’s when you would need to use a Lockout Cylinder.

What is a Lockout Cylinder? In a Lockout Cylinder, there are two rows of pin chamber in the shell. The row at 12 o’clock position is standard with all six pins in the chamber. The lockout row is in the 11 o’clock position and contains only the first four pins in the shell. The back two pin chambers are not drilled and because of the 11 o’clock row of top pins, the lock out cylinders is only available as a mortise or rim cylinder.

When the plug is in normal position, all key will operate the lock normally. To temporarily disable the regular operating keys, insert the special lockout key and turn it to the 11 o’clock position and remove the key. The cylinder now is in lockout mode.

How it works? To temporarily disable the regular operating keys, insert the special lockout key and turn it to the 11 o’clock position and remove the key. Now the cylinder is in lockout mode.

Operating key in lockout position – The regular operating key cannot come out in the lockout position because of the last two steeples. The last 2 pins are fully engaged and cannot move out of the way to clear the key’s steeples. Lockout Key in Lockout Position – Will enter and exit the cylinder in lockout position. Notice how the key’s last two steeples are removed so it can enter and exit the cylinder in lockout mode.

Operating key trying to enter in Lockout Mode – Notice how the last 2 pins cannot move out of the way to clear the incoming key. This is why a regular key cannot operate in lockout mode.
