Review: Works as intended - Working well so far. Easy to install.
Review: Works very well to install door lock on thicker doors - This is exactly what I needed for my mortise lock with skeleton key set. The door was a bit thicker than the standard, so I purchased this longer spindle and it works just as expected! Pleased with this purchase, and easy installation.
