DOOR HARDWARE - Hinges - Loose Pin VS Removable Pin

Question: What is the difference between loose pin and removable pin hinges?
Answer: Loose pin hinges have one of the finials attached to the end of the pin which can be pulled out for ease of installation and removal of doors. Removable pin hinges have a pin that is not attached to the finial and usually needs to be tapped out of the knuckle in order to separate the two sides of the hinge.
