A lever handle is a type of door hardware that operates a latch or locking mechanism by pushing down or lifting a horizontal lever instead of twisting a knob. Lever Handles are now the most common choice for residential, commercial, and institutional buildings, offering superior ergonomics, accessibility, and modern aesthetics.
They are designed for ease of use — a simple downward motion retracts the latch bolt, allowing the door to open smoothly. Lever handles are also a key element in universal design, making them ideal for children, seniors, and users with limited hand strength or mobility.
The basic operation of a lever handle involves four main components working together:
Lever Arm: The horizontal handle you push down or lift.
Spindle: A square bar connecting both levers through the door latch; it rotates when the lever is pressed.
Latch Mechanism: A spring-loaded bolt that retracts when the spindle turns, opening the door.
Strike Plate: The metal plate on the door frame where the latch bolt engages when the door is closed.
When you push the lever down, the spindle rotates and retracts the latch bolt — allowing the door to open. Releasing the lever lets the spring return the latch bolt to its extended position, keeping the door closed.
Lever handles are available in several functional types, each suited for different applications:
| Type | Locking Function | Common Application | Key Feature |
|---|---|---|---|
| Passage Lever | Non-locking | Hallways, closets | Operates latch only |
| Privacy Lever | Interior push-button or thumb-turn lock | Bedrooms, bathrooms | One-side locking with emergency release |
| Entry Lever | Keyed cylinder | Exterior or main doors | Keyed outside, thumb-turn inside |
| Dummy Lever | No latch or lock | Decorative or double doors | Fixed handle, purely aesthetic |
Many modern lever handles (like those made by Hangfat Metal) are reversible, meaning they can be installed on either left-hand or right-hand doors.
The performance and durability of a lever handle largely depend on the material used.
Stainless Steel (SUS304 / SUS316): Corrosion-resistant, ideal for coastal or humid environments.
Zinc Alloy: Cost-effective and supports a variety of plated finishes.
Brass: Durable and elegant, often used in luxury interiors.
Aluminum: Lightweight and practical for interior applications.
Hangfat Metal specializes in stainless-steel lever handles that combine mechanical strength with refined surface finishes — ensuring both reliability and design appeal.
Lever handles come in a wide range of finishes to complement different architectural themes:
Satin or Brushed Stainless Steel
Polished Chrome or Nickel
Matte Black Powder Coat
Antique Bronze
PVD Gold or Rose Gold
Designs range from round rosette handles for minimalist interiors to long backplate handles for traditional aesthetics.
Lever handles are easier to use than knobs — no need to twist or grip tightly. This makes them ADA-compliant and user-friendly for people of all abilities.
Their clean lines and sleek profiles enhance contemporary architecture, hospitality spaces, and office interiors.
Available in keyed, privacy, or passage forms to fit different door functions across a project.
High-quality lever handles made from stainless steel or zinc alloy withstand frequent use and resist corrosion, ideal for commercial environments.
They fit standard 54 mm bore holes with 60 mm or 70 mm backsets, allowing quick retrofit replacement without major carpentry.
