Product Features & Advantages

• Solid Stainless Steel Durability: One-piece forging process creates a seamless, impact-resistant lever—50% more durable than hollow handles, withstanding 100,000+ operation cycles (ideal for high-traffic areas like hotel lobbies or office buildings).
• Double-Sided Security: Symmetrical design ensures consistent grip and locking functionality on both sides of the door, eliminating security gaps found in single-sided handles (critical for exterior entry doors or private medical rooms).
• Integrated Privacy Lock: Internal thumbturn lock lets users secure spaces without keys, while the emergency access slot allows safe override (meets healthcare and hospitality safety regulations).
• System Compatibility: Works flawlessly with D&D’s concealed hinges (for a clean look), deadbolt locks (for enhanced security), and panic exit devices (for commercial public areas)—simplifying bulk procurement for full-door solutions.
• Corrosion Resistance: SUS304/SUS316 materials resist moisture, salt, and chemical wear—suitable for bathrooms, coastal homes, or industrial environments (outperforming standard door handles in harsh conditions).
• Global Compliance: CE, UL, and BHMA certified, meeting ANSI/EN standards for door hardware—ensuring seamless import and project approval in Europe, America, and Asia.

Step-by-Step Installation Guide

1. Gather tools: Phillips screwdriver, tape measure, level, drill, and hole saw (for pre-drilling lock mechanism holes).
2. Mark installation position: Align the lever centerline 36 inches from the floor (standard height) and mark spindle/lock hole positions—ensure alignment with your door lockset cutouts.
3. Drill pilot holes: Use a drill bit matching your spindle size (6-8mm) to avoid splitting wood doors or damaging metal doors.
4. Insert spindle: Slide the spindle through the door and connect it to your door lock mechanism—test rotation to ensure smooth movement.
5. Mount levers: Attach the exterior and interior levers to the spindle, securing them with included set screws (tighten until the lever doesn’t wiggle).
6. Test functionality: Lock/unlock the door to verify privacy lock operation; adjust door hinges if the lever doesn’t align with the door frame.

Application Scenarios

• Residential Spaces: Exterior entry doors (paired with D&D’s deadbolt locks), bedroom doors, and home offices—where privacy and family security are priorities.
• Hospitality Industry: Hotel guest rooms, spa treatment areas, and staff lounges—double-sided design ensures guest safety, while the modern finish complements luxury decor.
• Healthcare Facilities: Patient rooms, examination rooms, and medication storage closets—SUS316 material resists sanitizer corrosion, and the emergency slot meets medical safety standards.
• Commercial Offices: Private offices, meeting rooms, and HR departments—paired with D&D’s door closers for professional functionality and privacy control.
• Educational & Public Spaces: School counselor offices, library study rooms, and gym changing areas—durable construction withstands student/staff use, and the privacy lock protects personal space.

Value for Buyers

• Reduced Total Cost of Ownership: Solid construction and 10-year mechanical warranty minimize replacement and maintenance costs—critical for large-scale projects like apartment complexes or hotel chains.
• Streamlined Sourcing: Procure handles, door locks, door hinges, and door stoppers from one supplier—cutting logistics time, inventory complexity, and communication overhead.
• Project Flexibility: Multiple spindle sizes, diameters, and material options (SUS201-SUS316) adapt to budget constraints or high-performance requirements (e.g., SUS316 for coastal hotels).
• Faster Market Entry: Pre-certified (CE/UL) design eliminates regulatory delays, helping you deliver projects on schedule in global markets.
• Stable Supply Chain: 200,000 units/month production capacity ensures on-time delivery for bulk orders—even during peak construction seasons.

Certifications & Compliance

• Product Certifications: CE marked (EN 1906), UL listed (ANSI/BHMA A156.2), ensuring compliance with European and American door hardware safety standards.
• Quality Management System: ISO9001-certified production process—every lever undergoes dimensional, functional, and corrosion testing before shipment.
• Material Safety: SUS304/SUS316 stainless steel meets REACH and RoHS requirements—free from harmful substances, suitable for eco-friendly building projects.
• Accessibility Compliance: ADA-compliant lever design (easy to grip for users with limited hand mobility)—meeting public building regulations in global markets.
• Factory Validation: SGS-audited manufacturing facility—verifying production capacity, quality control, and ethical manufacturing practices.

Customization Options

• Material Tailoring: Choose SUS201 (budget-friendly for residential projects), SUS304 (standard for commercial use), or SUS316 (high-corrosion resistance for harsh environments).
• Finish Customization: PVD coatings (gold, bronze), matte black, or polished chrome—matching your project’s design language (e.g., matte black for modern offices, polished chrome for luxury hotels).
• Functional Modifications: Custom lock mechanisms (e.g., keyed override for high-security areas) or spindle lengths for non-standard door thicknesses.
• Branding & Packaging: OEM/ODM services for laser-engraved logos on levers; custom packaging (branded boxes, multilingual guides) for retail or distributor clients.
• Accessory Matching: Custom door plates or rosettes to complement the lever—creating a unified door hardware aesthetic for your project.

Production Process & Quality Control

1. Raw Material Inspection: Stainless steel bars undergo chemical composition testing (ensuring SUS304/SUS316 purity) and tensile strength checks—rejecting any substandard material.
2. Solid Forging: Bars are heated and forged into lever blanks—creating a dense, seamless structure that resists cracking (unlike hollow, welded alternatives).
3. CNC Machining: Precision CNC tools shape the lever, spindle hole, and lock mechanism recess—ensuring tight tolerances (±0.1mm) for compatibility with door locksets.
4. Surface Treatment: Levers undergo grinding, polishing, and coating (e.g., satin finish)—followed by 72-hour salt spray testing to validate corrosion resistance.
5. Lock Mechanism Integration: Privacy locks are assembled and tested for 50,000+ cycles—ensuring smooth thumbturn operation and reliable emergency access.
6. Final QA & Certification: Each lever is inspected for visual defects, functional performance, and certification compliance—only 100% qualified units are packaged and shipped.
