Sliding door handles are hardware components designed to facilitate the opening and closing of sliding doors. They come in various shapes, sizes, and materials to suit different types of sliding doors, such as glass patio doors, wardrobe doors, and interior sliding doors. The primary function of a sliding door handle is to provide a comfortable grip for users to easily slide the door along its track.

Here are some common types of sliding door handles:

1. Flush Pull Handles: These handles are designed to be flush with the surface of the door, offering a minimalist and sleek look. They are often used on sliding closet doors or cabinet doors.

2. D-handle Pulls: D-handle pulls are shaped like the letter "D" and are attached to the door's surface. They provide a sturdy grip and are commonly used on sliding patio doors.

3. Lever Handles: Lever handles offer a more ergonomic design, allowing users to open the door with a downward or upward motion. They are often used for interior sliding doors.

4. Recessed Handles: Recessed handles are inset into the door's surface, creating a clean and unobtrusive appearance. They are frequently found on sliding glass doors and shower doors.

5. Keyed Handles: Some sliding door handles come with locks that require a key for added security. These are commonly used on patio doors and other entry points.

6. Mortise Handles: Mortise handles are more complex and require a pocket or mortise to be cut into the edge of the door. They are commonly used in high-end applications.

Materials for sliding door handles can range from metal (like stainless steel or aluminum) to various finishes like brushed nickel, chrome, or brass. For interior sliding doors, handles may also be made of wood or plastic.

When choosing a sliding door handle, consider factors such as the door's weight and size, the location of the door (interior or exterior), the aesthetic of the room, and the level of security required.

Proper maintenance and occasional lubrication are essential to ensure smooth operation and longevity of sliding door handles.
