For furniture, handles, pulls, and knobs are mounted on only one side of the furniture because they are opened only from the outside.
Conversely, for interior doors, handles are often mounted to both the inside and outside.
In addition, sizes for furniture are smaller than those for interior doors.

What are handles, pulls, and knobs?
Pulls, handles, and knobs are the parts you hold to open or close doors and drawers on furniture or machinery.
In the next sections, we'll show you their appearance (material and finishing), explain how to install them, and provide tips for choosing the right product.
Types of Handles, Pulls, and Knobs
For Furniture
Back Screw Mount Handles
- Read More
-
Back screw mount handles are mounted with screws from the back of a drawer and cabinet.
By using them, you can give your furniture a seamless and elegant finish, as the screws will not be visible from the front.Video: The difference between a back screw mount handle and a surface mount handle
Front Screw Mount Handles
- Read More
-
Front screw mount handles are mounted from the front.
They are easy to position and mount. They are recommended when mounting from the back is not possible (there is no space in the back) or when you need to mount a handle to a place that is hard to reach.Video: The difference between a back mount handle and a surface mount handle
Knobs
- Read More
-
While handles are operated with a grip, knobs are often smaller and are operated with a pinching action with fingers.
For knobs with a specific directional orientation, like the ones shown below, sometimes have a rotation stopper in order to keep in the right position and direction.Rotation Stopper
Recessed Pulls
- Read More
-
Recessed pulls are embedded into doors and drawers so that they do not stick out.
Recessed pulls can be classified into two types based on the presence or absence of a "handle lip," which is a raised edge around the opening of the handle that helps to grip the pull with your fingers. Recessed pulls without a handle lip can only be moved sideways, making them ideal for sliding doors. On the other hand, recessed pulls with a handle lip can also be moved forward, making them suitable for hinged doors and drawers.
Rotating Pulls
- Read More
-
Rotating pulls are pulls with a grip that can rotate when in use and be made flat when not in use.
These are recommended for surfaces on which you don’t want to have protruding objects, such as floors and door end surfaces.
Retractable Handles
- Read More
-
Retractable handles (also known as trunk handles) are handles with a movable grip, which can be retracted when not in use.
There is also a type of retractable handle that automatically retracts using spring force.
Push Knobs
- Read More
-
Push knobs have a knob that protrudes when pushed. When not in use, these are safe because the knob component remains flush with the surface of the door and does not stick out.
A selection of push knobs in the same style with a latch mechanism are also available.
For Interior Doors
Interior doors have handles or knobs on both sides as they can be opened from either side. The handles and knobs designed for interior doors are larger and more durable than those intended for furniture.

Lever handles are used for wooden interior doors (hinged doors) and glass hinged doors.
They are used with a corresponding case lock (lock case). The latch mechanism is released to open doors when the lever handles are turned.

How to Select the Right Handle, Pull, or Knob
1. Select a Replacement with the Same Mounting Pitch
When replacing a pull or handle, select one with the identical mounting pitch as the previous one to reuse the existing screw holes. The mounting pitch of a pull or handle refers to the measurement between the centers of the mounting holes.
2. Total Design Coordination
Pulls and knobs are available in various designs and styles, including modern, natural, and antique, and using hardware from the same series, such as hooks or a towel rail, can help create a cohesive and visually appealing interior space.

3. Select SEMI-Compliant Handles for Semiconductor Equipment
SEMI compliance refers to the set of standards created to unify industrial standards worldwide in the semiconductor industry. The SEMI standards specify environmental, health, and safety guidelines, and regulations for handles are also included, so select a handle that complies with these standards.
