T-Series Tailpiece Installation
For proper function of the lock, the right tailpiece must be used and installed correctly.
All T-locks with standard cylinders must have the tailpiece installed
VERTICALLY on the cylinder as shown.
NOTE: The cap must be properly adjusted.
If too loose, excessive plug end play will prevent the key from being withdrawn.
If too tight, the plug will drag and be difficult to rotate with the key.
