Understanding Door Knobs and Spindles
Door knobs and spindles function together to allow for the operation of door locks. The knob is the external part that you turn to open or close the door, while the spindle is the internal rod that connects both knobs through the latch mechanism. Understanding their construction and functionality is crucial for proper installation and replacement.
Types of Door Knobs
Door knobs come in various styles and functions:
- Privacy Knobs: These knobs can be locked from the inside and are commonly used in bathrooms and bedrooms.
- Passage Knobs: These are non-locking knobs suitable for hallways and closets.
- Dummy Knobs: These are purely decorative and do not turn or lock, often used on non-functional doors.
The Role of Spindles
Spindles are vital components that transfer the rotational motion of a door knob to the latch mechanism. They are available in different types to suit various door systems:
- Solid Spindles provide a direct connection and are durable for standard use.
- Hollow Spindles offer adjustability, making them ideal for custom installations.
- Swivel Spindles allow for unique applications, such as sliding doors.
