Step-by-Step Installation Guide

1. Gather tools: Phillips screwdriver, tape measure, level, drill, and hole saw (for lock mechanism cutouts).
2. Mark installation height: Align the lever center 36 inches from the floor (standard height) and ensure alignment with door cylinder and door lock positions.
3. Prepare door: Drill holes for the spindle and lock mechanism, following dimensions specified for 35-55mm door thickness.
4. Insert spindle: Connect to your door lockset and test rotation to ensure smooth operation.
5. Mount lever handles: Attach both sides, securing with set screws—verify alignment with door hinges for proper function.
6. Final check: Test lever movement and compatibility with door closers (if installed); adjust as needed for optimal performance.

Production Process & Quality Control

1. Material Inspection: SUS304 stainless steel bars undergo chemical composition and tensile strength testing to ensure premium quality.
2. Solid Forging: Bars are heated and forged into lever blanks, creating a dense, uniform structure that resists cracking and deformation.
3. CNC Machining: Precision CNC tools shape the lever, spindle hole, and grip profile—ensuring tight tolerances for compatibility with door locksets.
4. Surface Treatment: Multi-step polishing and finishing process, followed by 72-hour salt spray testing to validate corrosion resistance.
5. Functional Testing: Each lever undergoes 50,000+ operation cycles to simulate 10+ years of use, ensuring smooth, reliable performance.
6. Final Certification: Comprehensive inspection for dimensional accuracy, finish quality, and compliance with CE/UL standards before packaging.
