A fixed pin hinge has a permanently attached pin, while a loose pin hinge allows you to remove the pin, making door removal much easier. Here's a breakdown:
Fixed Pin Hinge
- Pin: The pin is permanently fixed within the hinge.
- Door Removal: To remove a door using fixed pin hinges, you must unscrew the hinge leaves from either the door or the frame.
- Use Cases: Commonly used where easy door removal is not a frequent requirement.
- Pros: Typically more secure and less prone to accidental pin removal.
- Cons: Less convenient for removing doors quickly.
Loose Pin Hinge
- Pin: The pin can be easily removed from the hinge barrel.
- Door Removal: Allows for quick door removal; simply knock out the pin and lift the door off the hinges.
- Use Cases: Ideal for doors that need to be removed frequently for cleaning, moving furniture, or other maintenance.
- Pros: Convenient and fast door removal.
- Cons: Potentially less secure, and the pin can be lost or tampered with.
Summary Table
| Feature | Fixed Pin Hinge | Loose Pin Hinge |
|---|---|---|
| Pin Removal | Not removable | Removable |
| Door Removal | Requires unscrewing the hinge leaves | Simply remove the pin and lift the door |
| Convenience | Less convenient for frequent door removal | More convenient for frequent door removal |
| Security | Generally considered more secure | Potentially less secure |
| Common Usage | Standard door applications | Doors requiring easy removal (e.g., closet doors) |
In essence, the primary difference lies in the pin's removability, which directly impacts the ease with which a door can be removed from its frame. Choose a loose pin hinge if you anticipate needing to remove the door regularly; otherwise, a fixed pin hinge is generally suitable.
