Lever Door Handle
A lever-style door handle is the most common type of interior door handle. It features a horizontal bar that rotates downward when pressed, making it easy to operate with one hand or even an elbow. These handles are particularly beneficial for those with limited hand mobility and comply with ADA requirements. They're commonly used throughout homes and commercial buildings.

Doorknob
The traditional doorknob is a rounded handle that requires a twisting motion to operate. While classic in appearance, doorknobs require more grip strength than lever handles and may be challenging for children, elderly, or those with arthritis. They're often found in older homes and can add a traditional aesthetic to interior doors.

Pull Handle
Pull handles are fixed handles that don't turn or rotate. They're typically installed on doors that only need to be pulled open, often paired with a push plate on the opposite side. These are commonly found on closet doors, pocket doors, or sliding doors where a latching mechanism isn't necessary.

Push/Pull Plate
Push/pull plates are flat, rectangular plates mounted vertically on doors. They provide a surface for pushing or pulling a door open without a protruding handle. These are often used in commercial settings or on doors that don't require latching mechanisms, such as restaurant kitchen doors or bathroom entrance doors.

Flush Pull Handle
Flush pull handles are recessed into the door surface, creating a sleek, minimal appearance. They're commonly used on sliding doors, pocket doors, or cabinet doors where a protruding handle would interfere with the door's operation. These handles are ideal for spaces where you want to maintain a clean, modern aesthetic.

T-Handle
T-handles feature a T-shaped design that can be both pulled and turned. They're often used on screen doors, storm doors, or specialized interior applications. The design provides good grip and leverage for both pulling and turning operations.

Privacy Lock Handle
Privacy lock handles include a locking mechanism, typically operated by a push button or turn piece on the interior side. These handles are commonly used on bathroom and bedroom doors where privacy is desired but high security isn't necessary. They usually feature an emergency release option on the exterior side.

Passage Handle
Passage handles are non-locking door handles used on interior doors where privacy isn't needed. They operate the latch but don't include any locking mechanism. These are commonly used on closet doors, hallway doors, or any interior door where security isn't a concern.

Dummy Handle
Dummy handles are non-functioning handles that serve only as decorative pulls. They don't include any latching mechanism and are typically mounted on one side of the door only. These are often used on closet doors, double doors where only one side needs to operate, or decorative applications.
