A lever door handle is a type of door hardware that uses a horizontal handle lever instead of a traditional round knob to operate the latch mechanism. Lever Handles are widely used in homes, hotels, offices, and public buildings because they combine ergonomic comfort, modern aesthetics, and accessibility for users of all ages.
A typical lever door handle assembly includes several key parts:
Lever Handle: The horizontal arm that users push or pull to operate the latch.
Spindle: A square bar connecting both levers through the latch; when the lever turns, it retracts the latch bolt.
Latch Mechanism: The internal spring-loaded bolt that holds the door closed until the handle is turned.
Rosette or Backplate: The decorative plate covering the mounting screws and spindle hole.
Strike Plate: Mounted on the door frame, it receives the latch bolt when the door is closed.
Premium products like Hangfat Metal lever handles often feature precision-machined spindles, stainless-steel construction, and concealed screw designs for enhanced durability and a clean appearance.
Lever handles require minimal grip and wrist rotation, which makes them ideal for children, elderly users, or those with disabilities. This is why they’re often specified in ADA-compliant (Accessibility) buildings.
Lever handles provide a sleek, contemporary look suitable for minimalist and luxury interiors alike. Stainless-steel or brushed-nickel finishes complement modern design trends.
They come in multiple functional types:
Passage Levers: Non-locking; used for hallways or closets.
Privacy Levers: Include a push button or thumb turn for bathrooms and bedrooms.
Entry Levers: Operated by a key outside and thumb turn inside for security doors.
Dummy Levers: Fixed handles used on double doors or decorative panels.
Lever handles are available in stainless steel, zinc alloy, brass, or aluminum, offering different balances of cost, strength, and corrosion resistance.
High-grade SUS304 or SUS316 stainless steel handles (as offered by Hangfat Metal) are especially suitable for coastal or humid environments.
Most residential doors use a 54 mm bore hole with a 60 mm or 70 mm backset, and lever handles are designed to fit these standards.
Many designs are reversible, meaning one model fits both left-hand and right-hand doors — simplifying installation and replacement.
However, some mortise lever handles or commercial-grade sets require specific cutouts or door thicknesses. Always check product specifications before purchase.
Replacing or installing a lever handle is straightforward:
Insert the latch into the door edge (beveled side facing the jamb).
Slide the spindle through the latch hub.
Mount both lever handles and tighten screws evenly.
Snap on the decorative rosettes to conceal screws.
Install and align the strike plate on the frame.
