Lockable Lever door handles are push-button door handles with a locking function, made of stainless steel with a sleek, minimalist design and a smooth feel. They open and close doors via an internal mechanical transmission system and a rotary lock mechanism, with a design that prioritizes stability and ease of operation. Whether in a home or commercial environment, users can easily operate them, enjoying both everyday door opening and closing and secure locking. The complete set includes screws, wrenches, and mounting components, with standardized installation and simple maintenance.

Lockable Lever Door Handles Parameters:

Lockable Lever Door Handles Features:

• High Strength: The main body of the Lockable Lever Door Handles is made of SS304 or SS316 stainless steel. SS304's rust resistance is demonstrated by passing a 96-hour neutral salt spray test without red rust, while SS316, containing approximately 2% molybdenum, offers over 40% improved corrosion resistance in chlorinated environments. The connection between the handle and the lock body utilizes a thickened square shaft design with a strength exceeding 400 MPa.

  
  

• Wear Resistance: The surface is treated with PVD, brushed, or mirror polishing. The PVD coating thickness is controlled between 0.3 and 0.5 μm, with a surface hardness of approximately HV2000 or higher, providing four times the wear resistance life compared to traditional electroplating. The brushed surface roughness is controlled at Ra0.3 μm, effectively preventing fingerprint residue.

  
  

• Stability: An independent return spring design ensures automatic return within 0.3 seconds after each opening and closing, guaranteeing a consistent handle rebound angle and reducing fatigue wear. It meets EN1906 standards, with a return deviation not exceeding 1.5°. The thickened 9mm rose-top base provides better stability and support, ensuring a tight fit against the door surface and preventing loosening after long-term use.

  
  

• Safety: An internal precision locking knob system with a 90° rotation angle and operating torque controlled between 0.8–1.0 N·m prevents accidental operation by children while ensuring easy use by adults. Models with a red-green indicator window have an indicating area of 200mm², allowing clear status indication from a distance of 2 meters.

  
  

• Easy Installation: The complete set includes mounting screws, an Allen wrench, and a fixing kit, suitable for door panels 35–55mm thick. The screws are made of M4 stainless steel with a tensile strength of approximately 520MPa. Standard mounting hole spacing and fit accuracy are within ±0.1mm, ensuring coaxiality after assembly. Typical home users can complete installation in 15–20 minutes, saving construction time.

Lockable Lever Door Handles Application:

• Residential Bedrooms: Lockable Lever Door Handles are suitable for bedrooms and studies, rooms that require privacy but also prioritize daily convenience. 35-45mm thick finished doors are most common, featuring an inner knob for quick locking during rest, and an outer emergency slot that can be quickly opened with a coin or similar tool in emergencies, ensuring a balance between security and privacy.

• 
  

• Bathroom Enclosures: Suitable for bathroom doors in homes and apartments, the red and green indicator clearly shows occupancy status, reducing interference from opening the door. Mirror-polished or brushed surfaces are easier to maintain in humid, hot environments with cleaning agent residue, and offer superior resistance to water stains and fingerprints. A well-designed anti-loosening structure withstands vibrations from frequent opening and closing, maintaining a tight fit between the handle and rosette cover, preventing long-term shaking from affecting the sealing strip.

  
  

• Villas and Hotels: In the interior door scenarios of villa suites and mid-range hotel rooms, a unified surface color scheme helps maintain the overall style of the entire space. PVD black titanium or bronze can create a harmonious contrast with wood grain and stone, meeting the color control requirements of the design scheme. When used in multiple units over a long period, the mechanical life of 200,000 cycles can cover a typical table turnover cycle of three to five years in guest rooms, reducing maintenance costs.

  
  

• Hospitals: SS316 exhibits even greater corrosion resistance in chlorine-containing environments, making it suitable for areas with high disinfection frequencies, such as restrooms and nursing care rooms. The rounded handle design facilitates daily wiping, reducing hard-to-reach areas, and maintains surface shine when used with neutral or alcohol-based cleaners. Red and green indicator lights allow nursing staff to quickly assess room conditions, improving access efficiency.

Lockable Lever Door Handles FAQs:

1. What door thicknesses is this door handle suitable for?

It fits standard interior doors from 35–55 mm. If the door thickness exceeds or falls below this range, adjustment can be made by replacing the extended square shaft and screws. The manufacturer can also pre-install corresponding accessories according to customer dimensions in the order.

2. Is the handle interchangeable for left and right?

Yes, the product is a universal design suitable for both left- and right-opening doors. Simply adjust the direction during installation; no additional matching models are needed, saving on inventory costs.

3. Can this product be used in humid environments?

Yes. The SS304 version is suitable for ordinary residential or office environments, while the SS316 version performs better in high humidity or chlorine-containing environments (such as bathrooms and hospitals), and has been tested to operate stably for over 200 hours under salt spray conditions.

4. How to maintain and clean it?

It is recommended to use a neutral detergent and a soft cloth for wiping. Avoid acidic or alkaline solutions. The brushed or PVD surface does not require waxing; simply check the screw tightness regularly to maintain smooth operation.

5. What are the minimum order quantity and delivery time?

The minimum order quantity is 300 sets. The delivery time for standard surface treatment is 35–40 days. For customized colors, engravings, or specific SS316 material, the factory will adjust the delivery time according to the process and confirm the production plan in advance.
