• Universal Compatibility: Works with D&D’s door locks, concealed hinges, and door bolts—simplifying bulk orders for complete door systems.
• Ergonomic Design: Knurled grip (optional) improves handling; solid weight provides reassuring operation without fatigue—suitable for all users, including children and the elderly.
• Corrosion Resistance: SUS304/SUS316 materials withstand moisture (bathrooms) and harsh environments, outperforming standard door handles in longevity.
• Global Compliance: CE, UL, and BHMA certified, meeting ANSI/EN standards for safety and performance in international markets.

Step-by-Step Installation Guide

1. Gather tools: Phillips screwdriver, tape measure, level, drill, and hole saw (for lock mechanism cutouts).
2. Mark installation points: Align with standard height (36 inches from floor) and ensure alignment with door cylinder and door lock positions.
3. Prepare door: Drill holes for spindle and lock mechanism, matching specified dimensions (35-55mm door thickness).
4. Insert spindle: Connect to door lockset and secure with mounting screws—verify smooth rotation.
5. Attach lever handles: Mount interior (with thumbturn) and exterior levers, tightening set screws to secure.
6. Test functionality: Check lock/unlock operation, lever movement, and emergency access—adjust door hinges if needed for perfect alignment.

Application Scenarios

• Residential Spaces: Bedrooms, bathrooms, home offices, and garages—where privacy control is essential for family comfort.
• Hospitality Industry: Hotel guest rooms, spa treatment areas, and staff quarters—blending security with upscale aesthetics.
• Healthcare Facilities: Patient rooms, examination areas, and storage closets—hygienic stainless steel meets medical-grade standards.
• Commercial Offices: Private offices, meeting rooms, and HR departments—paired with D&D’s door closers for professional functionality.

Production Process & Quality Control

1. Raw Material Inspection: Stainless steel bars undergo tensile strength and corrosion resistance testing to ensure solid construction integrity.
2. Solid Forging: Precision forging creates one-piece lever blanks, eliminating welds and weak points common in hollow handles.
3. CNC Machining: Advanced machining shapes levers, spindles, and lock components to exact specifications (16-22mm diameters).
4. Surface Treatment: Multi-step finishing (including satin nickel) followed by 72-hour salt spray testing to validate corrosion resistance.
5. Lock Mechanism Integration: Privacy thumbturns are assembled and tested for 50,000+ cycles to ensure reliable operation.
6. Final QA Inspection: Each handle undergoes dimensional, functional, and visual checks—only 100% compliant units proceed to packaging.
